If your internet feels fine during the day but slow at night, you are not imagining it. Many people notice slower speeds, more buffering, higher ping and unstable video calls in the evening.

This usually happens because more people are online at the same time. Your household may be streaming, gaming and downloading, while your neighbours and other users on the network are doing the same.

This guide explains why your internet may be slower at night, how to test it properly, and what you can do before upgrading your package.

Quick answer

Your internet may be slower at night because of peak-time congestion, more people using the connection in your home, Wi-Fi interference, streaming, gaming, large downloads, cloud backups, ISP network load or fibre network congestion.

The best way to check is to run a speed test during the day, then run another one in the evening from the same device and location. If your evening result is much worse, your connection may be affected by peak-time usage or congestion.

Why internet often feels slower in the evening

Evening is the busiest time for home internet.

After work and school, more people are online at the same time. Families stream movies, watch YouTube, play online games, join video calls, scroll social media and download updates.

This can put pressure on your home network and sometimes your ISP’s network too.

In South Africa, this is especially noticeable in busy households, complexes, estates and areas where many people are using fibre, LTE, 5G or fixed wireless at the same time.

Peak time can affect your connection

Peak time usually refers to the busy hours when many people are using the internet.

For home internet, this is often in the evening.

During peak time, you may notice:

• Lower download speeds
• Lower upload speeds
• Higher ping
• More jitter
• More buffering
• Slower browsing
• Gaming lag
• Video calls freezing
• Streaming quality dropping

The connection may not be completely broken, but it can feel less responsive.

Your household may be using more bandwidth at night

Before blaming your ISP, check what is happening inside your own home.

At night, more devices may be active:

• Smart TVs streaming Netflix, YouTube, Showmax or DStv Stream
• Phones watching TikTok, Instagram or YouTube
• Gaming consoles downloading updates
• Laptops syncing files
• Security cameras uploading footage
• Tablets and phones doing cloud backups
• Multiple people using video calls or streaming at once

Even one large download can make the internet feel slow for everyone else.

Streaming can use a lot of speed

Streaming is one of the biggest reasons home internet slows down at night.

A single HD stream can use a fair amount of bandwidth. A 4K stream can use much more.

If one person is watching 4K video, another is gaming, and someone else is downloading a large update, your connection can quickly feel overloaded.

This is especially true on lower-speed packages or when the Wi-Fi signal is weak.

Game updates can slow down the whole house

Gaming itself does not always use a huge amount of data while playing, but game downloads and updates can be massive.

PlayStation, Xbox, Steam, Epic Games and other platforms can download large updates in the background.

If a console or PC starts downloading at night, it can affect everyone in the house.

You may notice:

• Web pages loading slowly
• Streaming buffering
• Video calls freezing
• High ping in games
• Poor loaded ping
• Slow speed test results

If your internet suddenly becomes slow at night, check whether a console, PC or phone is downloading updates.

Uploads can make the internet feel terrible

Uploads are often ignored, but they can cause major problems.

Cloud backups, WhatsApp backups, iCloud, Google Drive, OneDrive, CCTV uploads and large file uploads can fill your upload connection.

When your upload is maxed out, your internet can feel broken even if your download speed is not terrible.

This can cause:

• Laggy online games
• Frozen video calls
• Slow browsing
• Messages sending slowly
• High loaded ping
• Bufferbloat

If your speed test shows high loaded ping, your connection may be struggling when the line is under load.

Wi-Fi interference can be worse at night

At night, more nearby Wi-Fi networks are active.

If you live in a flat, complex, estate or dense neighbourhood, your router may be competing with many other routers nearby.

This can make Wi-Fi feel slower or less stable, especially on the 2.4 GHz band.

You may notice that your internet is fine close to the router but bad in another room.

In that case, the problem may be Wi-Fi coverage or interference, not only your ISP.

LTE and 5G can slow down during busy times

If you use LTE, 5G or fixed wireless internet, evening slowdowns can be caused by tower congestion.

Mobile networks are shared between many users in the area. When more people connect and use data at the same time, speeds can drop.

This can affect:

• Download speed
• Upload speed
• Ping
• Jitter
• Streaming quality
• Gaming performance

If your LTE or 5G internet is always slower at night, signal strength and tower load may be part of the problem.

Fibre can also feel slower at night

Fibre is usually more stable than mobile internet, but it can still feel slower at night.

Possible reasons include:

• Heavy usage in your home
• Poor Wi-Fi coverage
• Router limitations
• ISP congestion
• Fibre network congestion
• Routing issues
• Large downloads or uploads

If your fibre speed drops badly every evening, test with Ethernet if possible. This helps show whether the issue is your Wi-Fi or the actual internet line.

How to test if your internet is slower at night

Run a speed test during the day when the internet feels normal.

Then run another speed test at night when the internet feels slow.

Use the same device, same room and same Wi-Fi network if possible.

Compare:

• Download speed
• Upload speed
• Ping
• Jitter
• Loaded ping

If your results are much worse at night, the slowdown may be related to peak-time usage, congestion or household demand.

If the results are similar but the internet still feels slow, the issue may be app-specific, device-specific or related to Wi-Fi signal quality.

Test close to the router

If your evening speed is poor, test again close to the router.

If the result improves a lot near the router, your Wi-Fi signal may be the problem.

If the result is still poor close to the router, the issue may be your router, internet package, ISP or network congestion.

For the cleanest test, use Ethernet if your laptop supports it.

Check who or what is using the internet

Before upgrading your line, check what is using the connection.

Look for:

• Game downloads
• Windows updates
• Phone backups
• Cloud storage syncing
• Smart TV streaming
• 4K video
• CCTV uploads
• Multiple people streaming at once
• Large file uploads

If possible, pause downloads and backups, then run another speed test.

If the connection improves, your internet may not be broken. It may just be overloaded.

Is your package too slow for your household?

A package that worked fine a few years ago may not be enough anymore.

More homes now have smart TVs, streaming apps, cloud backups, online gaming, remote work and many connected devices.

As a rough guide:

• 10 Mbps can feel limited for a modern household
• 25 Mbps can work for light use
• 50 Mbps is better for small families
• 100 Mbps or more is better for busy homes
• Higher speeds may help if many people stream, game and work online at once

But speed is not everything. A better router or mesh Wi-Fi system may help more than a faster package if your real issue is weak Wi-Fi coverage.

What you can do to improve evening internet performance

Try these fixes:

• Restart your router
• Move closer to the router
• Pause large downloads
• Schedule game updates for late night
• Pause cloud backups during busy hours
• Use Ethernet for gaming, work calls or smart TVs
• Use 5 GHz Wi-Fi when close to the router
• Move your router to a better position
• Disconnect devices you are not using
• Upgrade an old router
• Use mesh Wi-Fi for larger homes
• Test with Ethernet before blaming your ISP

These steps can often improve the connection without changing your internet package.

When should you contact your ISP?

Contact your ISP if:

• Speeds are much worse every evening
• Ethernet is also slow at night
• All devices are affected
• Your router and ONT look normal but speed is poor
• Your package speed is much higher than your test results
• The problem happens at the same time every day
• Restarting does not help

When you contact your ISP, give them speed test results from different times of day.

For example, send them a daytime test and an evening test. Also tell them whether you tested over Wi-Fi or Ethernet.

This gives them more useful information than simply saying “my internet is slow”.

Should you upgrade your internet package?

Upgrading can help if your household regularly uses more bandwidth than your current package can handle.

But do not upgrade too quickly.

First check whether the real problem is:

• Weak Wi-Fi signal
• Old router
• Bad router placement
• Too many background downloads
• Uploads causing loaded ping problems
• ISP congestion
• One device causing issues

If your speed is good close to the router but bad in other rooms, a better router or mesh Wi-Fi may help more than a faster package.

If your speed is poor even on Ethernet, then your package, ISP or line may need attention.

Final thoughts

Internet that slows down at night is usually caused by more people using the connection at the same time.

The cause could be inside your home, on your Wi-Fi network, on your ISP’s network, or on a mobile tower if you use LTE or 5G.

Start by running speed tests at different times of day. Test during the day, test at night, and test close to your router.

If your results drop badly in the evening, you may be dealing with peak-time congestion, household usage or ISP/network load.

Use Lekker Speed Test to check your download speed, upload speed, ping, jitter and loaded ping so you can see what is actually happening.

A laptop that will not connect to Wi-Fi can be frustrating, especially when your phone, TV or other devices are working fine.

Sometimes the problem is your home internet. But very often, if only your laptop is having trouble, the issue is with the laptop itself, the saved Wi-Fi settings, the Wi-Fi adapter, the signal strength or a temporary network problem.

This guide explains why your laptop may not connect to Wi-Fi and what you can try before calling your ISP.

Quick answer

Your laptop may not connect to Wi-Fi because Wi-Fi is switched off, airplane mode is on, the saved network details are wrong, the signal is weak, the router is having issues, the Wi-Fi driver is outdated, VPN or security software is interfering, or your internet connection is down.

The first thing to check is whether other devices can connect to the same Wi-Fi network. If other devices work, the problem is probably your laptop. If nothing connects, the problem is more likely your router, fibre ONT, ISP or internet line.

First check: do other devices have internet?

Before changing laptop settings, check another device on the same Wi-Fi network.

Use your phone, tablet, smart TV or another laptop and try opening a website.

If other devices connect and work normally, your home internet is probably fine and the issue is likely on your laptop.

If no devices can connect or nothing has internet, the problem is more likely with your router, fibre ONT, ISP or internet connection.

This simple check helps you avoid blaming the wrong thing.

Wi-Fi connected vs internet working

There are two different problems that can happen.

Your laptop may fail to connect to Wi-Fi at all.

Or your laptop may connect to Wi-Fi, but still show no internet.

If it cannot connect to Wi-Fi, the problem is between your laptop and the router.

If it connects to Wi-Fi but has no internet, the laptop is connected to the router, but something is stopping it from reaching the internet.

The fix depends on which problem you have.

Common signs of laptop Wi-Fi problems

You may have a laptop Wi-Fi issue if:

• Your laptop cannot see your Wi-Fi network
• Your laptop sees the network but will not connect
• It says “can’t connect to this network”
• It asks for the Wi-Fi password again and again
• It connects but says “no internet”
• It keeps disconnecting from Wi-Fi
• Other devices work but the laptop does not
• Wi-Fi works close to the router but not in another room

Try to notice exactly what the laptop is doing. The message on the screen can help point to the cause.

1. Make sure Wi-Fi is turned on

This sounds obvious, but it is one of the easiest things to miss.

Check that Wi-Fi is switched on in your laptop settings.

Also check whether your laptop has a physical Wi-Fi button or keyboard shortcut. Some laptops use a function key to turn Wi-Fi on or off.

Look for a key with a wireless symbol. It may need to be pressed with the Fn key.

If Wi-Fi is off, your laptop may not show any nearby networks at all.

2. Check airplane mode

Airplane mode turns off wireless connections.

If airplane mode is enabled, your laptop may not connect to Wi-Fi even if the router is working properly.

On Windows, check the quick settings area near the clock and make sure airplane mode is off.

On a MacBook, check your Wi-Fi settings and make sure Wi-Fi is enabled.

After turning airplane mode off, give the laptop a few seconds to find nearby networks again.

3. Restart the laptop

A restart can fix temporary Wi-Fi problems.

Do a proper restart, not just sleep mode. Shut the laptop down or restart it from the menu.

This can clear small software issues, stuck network processes or temporary driver problems.

After restarting, try connecting to Wi-Fi again.

4. Restart your router and fibre ONT

If your laptop is not connecting, restart your router.

If you have fibre, you may also have a separate ONT. The ONT is usually the small box where the fibre cable enters your home.

Turn the router and ONT off, wait about 30 seconds, then turn them back on.

Wait a few minutes for everything to reconnect fully before testing again.

If other devices are also having issues, this step is especially important.

5. Forget the Wi-Fi network and reconnect

Your laptop saves Wi-Fi network details, including the network name, password and connection settings.

Sometimes those saved details can cause problems.

Forget the Wi-Fi network, then reconnect from scratch.

On Windows, go to your Wi-Fi settings, find the saved network, choose “forget”, then reconnect using your Wi-Fi password.

On a MacBook, remove the Wi-Fi network from known networks, then connect again.

This is a good fix if your laptop keeps saying it cannot connect to a network it used to connect to before.

6. Check the Wi-Fi password

If your router password was changed, your laptop may keep trying to connect with the old saved password.

Forget the network and enter the password again carefully.

Wi-Fi passwords are case-sensitive, so capital letters matter.

Also check whether you are connecting to the correct Wi-Fi network. In flats, estates and complexes, nearby Wi-Fi names can look similar.

7. Move closer to the router

Your laptop may not connect properly if the Wi-Fi signal is too weak.

Move closer to the router and try again.

If the laptop connects near the router but not in another room, the issue is probably Wi-Fi coverage.

This can happen if the router is too far away, hidden in a cupboard, blocked by walls, or placed in a poor spot.

In that case, the problem is not necessarily the laptop or your ISP. It may be the Wi-Fi signal in that part of the house.

8. Try the 2.4 GHz or 5 GHz Wi-Fi network

Many routers have two Wi-Fi bands: 2.4 GHz and 5 GHz.

2.4 GHz usually reaches further, but it is often slower.

5 GHz is usually faster, but it does not travel as far through walls.

If your router shows separate network names, try connecting to the other one.

If you are close to the router, try 5 GHz.

If you are further away, try 2.4 GHz.

Some laptops, especially older ones, may not support every Wi-Fi band or newer router setting.

9. Update the Wi-Fi driver

On Windows laptops, Wi-Fi problems can be caused by an outdated, broken or incorrect Wi-Fi adapter driver.

The Wi-Fi adapter is the part inside the laptop that handles wireless connections.

If your laptop keeps disconnecting, cannot connect, or says “no internet” while other devices work, the Wi-Fi driver may be part of the problem.

You can check for driver updates through Windows Update or Device Manager.

After updating, restart the laptop and test again.

10. Run the network troubleshooter

Windows has a built-in network troubleshooter that can sometimes detect and fix simple Wi-Fi issues.

It may reset the adapter, renew network settings or point out a problem.

It does not fix everything, but it is worth trying before making bigger changes.

Search for “Network troubleshooter” in Windows settings and follow the steps.

11. Turn off VPN or security software temporarily

A VPN, firewall, antivirus or security app can sometimes interfere with your connection.

If your laptop connects to Wi-Fi but websites do not load, turn off your VPN and test again.

Also check whether any security software is blocking the connection.

You do not need to uninstall anything immediately. Just test with the VPN or security tool disabled to see if it changes the result.

12. Check if your laptop works on another Wi-Fi network

Try connecting your laptop to another Wi-Fi network, such as a phone hotspot or another home network.

If the laptop works on another network, the problem may be your router, Wi-Fi settings or home network.

If the laptop does not work on any Wi-Fi network, the issue is more likely with the laptop, Wi-Fi adapter, driver or software settings.

This is one of the best ways to separate a laptop problem from a home Wi-Fi problem.

13. Try Ethernet if your laptop supports it

If your laptop has an Ethernet port, plug it directly into the router with a network cable.

If Ethernet works but Wi-Fi does not, your internet connection is probably working and the problem is likely the laptop Wi-Fi, router Wi-Fi or wireless signal.

If Ethernet also does not work, the issue may be with the router, ISP, fibre ONT or internet line.

Many newer laptops do not have Ethernet ports, but you can use a USB Ethernet adapter if needed.

14. Your router settings may not support the laptop

Sometimes a router setting can stop an older laptop from connecting.

This can happen with certain Wi-Fi security modes, newer Wi-Fi standards or band settings.

If the laptop is older and all newer devices connect fine, the router may be using settings the laptop does not handle well.

In that case, you may need to check the router Wi-Fi settings or ask your ISP for help.

Do not change advanced router settings unless you know what they do or can change them back.

15. Your ISP may have a problem

If your laptop connects to Wi-Fi but there is no internet, and every other device also has no internet, your ISP or fibre line may be the problem.

Possible causes include:

• Fibre line fault
• ISP outage
• LTE or 5G signal problem
• Account issue
• Router issue
• ONT problem
• Area network problem

Check the router and ONT lights, restart the equipment, and check your ISP’s outage notices.

If nothing works on any device, contact your ISP.

If only your laptop will not connect

If every other device works, try these steps:

• Restart the laptop
• Make sure Wi-Fi is on
• Turn airplane mode off
• Forget the Wi-Fi network and reconnect
• Check the Wi-Fi password
• Move closer to the router
• Try another Wi-Fi band
• Turn off VPN
• Run the network troubleshooter
• Update the Wi-Fi driver
• Test on another Wi-Fi network

If the laptop fails on multiple Wi-Fi networks, the laptop itself may need further troubleshooting.

If no devices can connect

If nothing can connect or nothing has internet, try these steps:

• Restart the router
• Restart the fibre ONT
• Check the router lights
• Check cables and power
• Check your ISP account
• Check for area outages
• Test with Ethernet if possible
• Contact your ISP if the issue continues

In this case, the laptop is probably not the main problem.

How to test after fixing the connection

Once your laptop is connected again, run a speed test.

Test close to the router first.

Then test again in the room where you normally use the laptop.

If the speed drops a lot in that room, your Wi-Fi coverage may be weak there.

If your download and upload speeds look fine but the laptop still feels laggy, also look at ping, jitter and loaded ping.

Those results can explain problems with video calls, gaming and general responsiveness.

When should you contact your ISP?

Contact your ISP if:

• No devices have internet
• The router or ONT shows a fault light
• Ethernet also does not work
• The connection keeps dropping on all devices
• Restarting the router and ONT does not help
• Your package is active but the line seems down

When contacting your ISP, tell them whether the issue is only on your laptop or on all devices.

That detail matters.

If only your laptop has the problem, your ISP may not be able to fix it because the internet line itself may be working.

Final thoughts

If your laptop is not connecting to Wi-Fi, start with the simple checks first.

Make sure Wi-Fi is on, airplane mode is off, and the password is correct. Then restart the laptop, forget the network and reconnect.

If other devices work, the problem is probably your laptop, Wi-Fi settings, driver or signal strength.

If no devices work, the issue is more likely your router, fibre ONT, ISP or internet line.

Once your laptop is connected again, use Lekker Speed Test to check your download speed, upload speed, ping, jitter and loaded ping.

Wi-Fi that keeps disconnecting is one of the most annoying internet problems. It can interrupt video calls, kick you out of online games, stop downloads, break streaming apps and make your internet feel unreliable.

The tricky part is that disconnecting Wi-Fi does not always mean your internet line is broken. Sometimes the problem is your router, weak Wi-Fi signal, one specific device, interference, or the way your home network is set up.

This guide explains why your Wi-Fi may keep disconnecting and what you can check before contacting your ISP.

Quick answer

Your Wi-Fi may keep disconnecting because of weak signal, poor router placement, router issues, interference, too many connected devices, old equipment, power-saving settings, device problems or an issue with your internet provider.

The first thing to check is whether the problem happens on every device or only one device. If only one phone, laptop or TV keeps disconnecting, the issue is probably with that device. If every device disconnects, the problem is more likely your router, Wi-Fi coverage, fibre ONT or ISP connection.

Wi-Fi disconnecting vs internet disconnecting

Before fixing the problem, it helps to understand the difference between Wi-Fi disconnecting and internet disconnecting.

Wi-Fi is the wireless connection between your device and your router.

Internet is the connection from your router to your ISP and the outside world.

If your Wi-Fi disconnects, your device may lose connection to the router completely.

If your internet disconnects, your device may still show that it is connected to Wi-Fi, but websites and apps will not work.

These two problems can feel similar, but the cause may be different.

Check if the problem happens on all devices

This is the most important first step.

If your phone, laptop, smart TV and gaming console all disconnect at the same time, the issue is probably not one specific device. It may be the router, fibre ONT, Wi-Fi coverage, power, or ISP connection.

If only one laptop or phone keeps disconnecting while everything else works fine, the problem is more likely on that device.

This helps you avoid wasting time changing router settings when the issue is actually a laptop driver, phone setting or weak signal in one room.

Common signs of Wi-Fi disconnection problems

You may have this issue if:

• Your phone keeps switching from Wi-Fi to mobile data
• Your laptop disconnects from Wi-Fi during video calls
• Your smart TV stops streaming and reconnects later
• Online games kick you out
• Downloads fail halfway through
• Your device says “connected without internet”
• The Wi-Fi icon disappears and comes back
• The problem is worse in certain rooms

Take note of when and where it happens. That can help you find the real cause.

1. Weak Wi-Fi signal

Weak signal is one of the most common reasons Wi-Fi keeps disconnecting.

If you are far from the router, behind thick walls, upstairs, outside, in a garage or in a back room, your device may struggle to keep a stable connection.

A weak signal can cause:

• Slow speeds
• High ping
• Buffering
• Random disconnects
• Video call problems
• Gaming lag

Try moving closer to the router and testing again. If the Wi-Fi becomes stable near the router, your issue is probably coverage.

2. Bad router placement

Router placement can make a big difference.

If your router is inside a cupboard, behind a TV, under a desk, next to large appliances or in the far corner of the house, your Wi-Fi signal may struggle to reach every room.

For better coverage, place your router:

• In a central part of the home
• Off the floor
• Away from thick walls
• Away from microwaves
• Away from large metal objects
• Out in the open

In many South African homes, the router is placed where the fibre cable enters the house. That is not always the best place for Wi-Fi coverage.

3. Router or fibre ONT issues

If all devices disconnect or lose internet at the same time, check your router and fibre ONT.

The ONT is usually the small box where the fibre cable enters your home. Some homes have a separate ONT and router, while others may have combined equipment.

Restart both devices if you have them.

Turn them off, wait about 30 seconds, then turn them back on. Give the connection a few minutes to come back online properly.

Also check if any lights look different from normal. A red or flashing fault light may point to a line problem.

4. Too many devices are connected

A router can struggle when many devices are connected at the same time, especially if it is an older or basic model.

A modern home can easily have many connected devices:

• Phones
• Laptops
• Tablets
• Smart TVs
• Gaming consoles
• Security cameras
• Smart speakers
• Streaming boxes
• Printers

Even if not all devices are being used, they may still be syncing, updating or using the connection in the background.

If your Wi-Fi disconnects more often when the whole household is online, your router may be overloaded or your internet package may be under pressure.

5. Large downloads or uploads

Big downloads and uploads can make your connection unstable, especially on slower packages.

Common examples include:

• Windows updates
• Game downloads
• PlayStation, Xbox or Steam updates
• Cloud backups
• Google Drive, iCloud or OneDrive syncing
• WhatsApp backups
• CCTV uploads
• 4K streaming

Uploads can be especially bad for connection quality. A heavy upload can increase loaded ping and make browsing, gaming and video calls feel broken even when the internet is technically still connected.

If your Wi-Fi drops or becomes unstable during downloads, pause the download and test again.

6. Wi-Fi interference

Wi-Fi can be affected by interference from other devices and nearby networks.

This is common in flats, complexes, estates and busy neighbourhoods where many routers are close together.

Interference can come from:

• Other Wi-Fi networks
• Microwaves
• Bluetooth devices
• Baby monitors
• Thick walls
• Metal objects
• Large appliances
• Poor router placement

If your Wi-Fi disconnects more often in one area of the house, interference or weak signal may be the cause.

7. Your device may be switching between Wi-Fi bands

Many routers use both 2.4 GHz and 5 GHz Wi-Fi.

2.4 GHz usually reaches further but can be slower and more crowded.

5 GHz is usually faster but does not travel as far through walls.

Some routers combine both bands under one Wi-Fi name. Your device may switch between them automatically, and in some cases that switch can cause drops or unstable performance.

If your router shows separate Wi-Fi names, try connecting to one band and testing it.

Use 5 GHz when you are close to the router.

Use 2.4 GHz when you are further away and need better range.

8. Your laptop or phone may be the problem

If only one device keeps disconnecting, the issue may be with that device.

For a phone, try:

• Restarting the phone
• Forgetting the Wi-Fi network and reconnecting
• Turning Wi-Fi off and on
• Turning airplane mode on and off
• Checking for software updates
• Disabling VPN
• Testing on another Wi-Fi network

For a laptop, try:

• Restarting the laptop
• Forgetting and reconnecting to Wi-Fi
• Updating the Wi-Fi adapter driver
• Turning off battery-saving Wi-Fi settings
• Testing with Ethernet
• Testing with a USB Wi-Fi adapter

If the same device disconnects from different Wi-Fi networks, the problem is probably the device and not your home internet.

9. Power-saving settings can cause disconnects

Some laptops and phones use power-saving features that can affect Wi-Fi.

A laptop may reduce power to the Wi-Fi adapter to save battery. This can sometimes cause the connection to drop, especially when the device is idle or under load.

If your laptop keeps disconnecting from Wi-Fi, check the Wi-Fi adapter power settings and battery-saving mode.

This is especially worth checking if the problem happens more often when the laptop is unplugged.

10. Your router may be old or overheating

Old routers can become unstable over time.

A router may still turn on and broadcast Wi-Fi, but struggle with modern usage, faster fibre packages or many connected devices.

Signs of a router problem include:

• Wi-Fi drops on multiple devices
• The router needs frequent restarts
• Speeds are inconsistent
• The router feels very hot
• The connection gets worse over time
• The router is several years old

Make sure the router has airflow and is not covered, stacked under other electronics or placed in direct sunlight.

If you constantly need to restart it, it may be time to replace it.

11. ISP or fibre network problems

Sometimes the issue is not inside your home.

Your ISP or fibre network may have a problem, especially if all devices lose internet at the same time.

Possible causes include:

• Area outages
• Fibre line faults
• Network maintenance
• Routing issues
• Congestion
• Faulty ONT
• Account or service problems

If Wi-Fi stays connected but the internet stops working on every device, it may be an ISP or line issue rather than a Wi-Fi issue.

How to test what is causing the disconnections

Start with a simple test.

When the problem happens, check whether the Wi-Fi icon disappears or whether the device still says it is connected.

If the Wi-Fi icon disappears, the device may be losing connection to the router.

If the Wi-Fi icon stays connected but nothing loads, the router may be losing internet.

Then check another device.

If only one device fails, troubleshoot that device.

If every device fails, check the router, ONT, power, cables and ISP status.

Try a speed test in different rooms

Run a speed test close to the router.

Then run another speed test in the room where the Wi-Fi keeps disconnecting.

If the speed, ping or jitter is much worse in that room, the problem may be Wi-Fi coverage.

You can also test at different times of day. If the problem is worse in the evening, it may be caused by household usage, nearby Wi-Fi congestion or ISP congestion.

Easy fixes for Wi-Fi that keeps disconnecting

Try these before upgrading your package:

• Restart your router
• Restart your fibre ONT
• Restart the device
• Move closer to the router
• Move the router to a better position
• Forget the Wi-Fi network and reconnect
• Disconnect unused devices
• Pause large downloads and uploads
• Use Ethernet for gaming, work calls or smart TVs
• Try the 2.4 GHz or 5 GHz Wi-Fi network
• Update router firmware if available
• Update laptop Wi-Fi drivers
• Replace an old router
• Use a mesh Wi-Fi system for larger homes

When should you contact your ISP?

Contact your ISP if:

• Every device loses internet
• Ethernet also disconnects
• The fibre ONT shows a fault light
• Restarting the router and ONT does not help
• Your connection drops at the same time every day
• Your router is online but there is no internet
• Your ISP package is active but the line keeps going down

When you contact support, tell them:

• Whether one device or all devices are affected
• Whether Wi-Fi disconnects or only the internet stops working
• Whether Ethernet works
• What the router and ONT lights show
• When the problem started
• How often it happens

This makes it easier for your ISP to understand the issue.

Final thoughts

Wi-Fi that keeps disconnecting can be caused by weak signal, poor router placement, interference, too many devices, an old router, device settings or ISP problems.

The best first step is to check whether the issue affects one device or every device.

If one device disconnects, troubleshoot that device.

If every device disconnects, check your router, fibre ONT, Wi-Fi coverage and ISP connection.

Use Lekker Speed Test to check your download speed, upload speed, ping, jitter and loaded ping. Testing in different rooms can help show whether the problem is your Wi-Fi signal or your internet connection.

Seeing “connected without internet” can be confusing. Your phone, laptop or TV says it is connected to Wi-Fi, but websites do not load, apps do not work and your internet still feels completely dead.

This usually means your device has connected to your router, but the router or device cannot reach the internet properly.

In other words, your Wi-Fi connection and your internet connection are not always the same thing.

Quick answer

If your device says it is connected to Wi-Fi but has no internet, it means the device is connected to your router, but something is stopping it from reaching the internet.

The problem could be your router, fibre ONT, ISP, device settings, DNS, a weak signal, an unpaid account, an outage in your area or a temporary connection issue.

The best first step is to check whether the problem affects one device or every device in the house.

Wi-Fi connected does not always mean internet connected

Wi-Fi is the wireless connection between your device and your router.

The internet is the connection from your router to the outside world.

That means your device can connect to Wi-Fi successfully, but still have no internet access.

For example, your phone may connect to your home Wi-Fi network, but if your fibre line is down, your ISP has an issue, or your router is not getting internet, your phone will still show a Wi-Fi connection with no working internet.

This is why “connected to Wi-Fi” does not always mean “connected to the internet”.

Common signs of this problem

You may have this issue if:

• Your device says “connected without internet”
• Your phone shows a Wi-Fi icon but apps do not load
• Your laptop connects to Wi-Fi but websites do not open
• Your smart TV says it is connected but streaming apps fail
• WhatsApp messages do not send
• You cannot run a speed test
• Other devices may or may not have internet

The most important thing is to work out whether it is only one device or the whole connection.

Step 1: Check if other devices have internet

Before changing settings, check another device.

Try opening a website on your phone, laptop, tablet or smart TV while connected to the same Wi-Fi.

If every device is connected to Wi-Fi but has no internet, the problem is probably with the router, fibre ONT, ISP or internet line.

If only one device has the problem, the issue is more likely on that specific phone, laptop or TV.

This one check can save you a lot of time.

Step 2: Restart your router and device

A restart sounds basic, but it often fixes temporary connection problems.

Turn off your router and fibre ONT if you have one. Wait about 30 seconds, then turn them back on.

Also restart the device that is giving the “connected without internet” message.

Give the router a few minutes to reconnect fully before testing again.

In many homes, especially with fibre, the router and ONT are separate boxes. The ONT is usually the device where the fibre cable enters your home. If both are present, restart both.

Step 3: Check your router and ONT lights

Look at the lights on your router or fibre ONT.

If the internet, broadband, LOS, PON or optical light looks different from normal, there may be a line issue.

A red LOS light, for example, often points to a fibre signal problem. If your ONT shows a fault light, restarting may not fix it and you may need to contact your ISP.

You do not need to understand every light on the device. Just check whether something looks obviously wrong compared to normal.

Step 4: Check if your ISP has an outage

If every device has no internet, your ISP or fibre network may be having a problem.

This can happen because of:

• Fibre line faults
• Area outages
• Load-related network issues
• Maintenance
• ISP routing problems
• Account or service problems

Check your ISP’s website, app, WhatsApp support, social media pages or outage notices if they provide them.

In South Africa, fibre networks and ISPs are often separate. Your ISP may need to check with the fibre network operator if the line itself is down.

Step 5: Forget the Wi-Fi network and reconnect

If only one device has the problem, try forgetting the Wi-Fi network and reconnecting.

On most phones and laptops, you can go to the Wi-Fi settings, select your network, choose “forget” or “remove”, and then connect again using your Wi-Fi password.

This can fix saved network settings that are no longer working properly.

It is especially useful if other devices work fine but one phone or laptop keeps saying it has no internet.

Step 6: Turn off VPN or private DNS settings

A VPN or custom DNS setting can sometimes make it look like the internet is broken.

If you use a VPN, turn it off and test again.

Also check whether your phone or laptop is using custom DNS, private DNS, security software or filtering apps.

These tools can be useful, but if something is configured incorrectly, your device may connect to Wi-Fi and still fail to load websites.

Step 7: Check if you need to sign in

Some Wi-Fi networks need you to sign in before the internet works.

This is common at hotels, airports, restaurants, universities, offices and public Wi-Fi hotspots.

Your device may show that it is connected to Wi-Fi, but the internet will not work until you accept terms, enter a code or log in on a captive portal page.

Try opening a normal website in your browser. If a login page appears, complete it and test again.

This is less common on home Wi-Fi, but very common on public Wi-Fi.

Step 8: Check your account or data balance

If you use LTE, 5G, fixed wireless or prepaid internet, check whether your data has run out.

If you use fibre, check whether your account is active and paid.

Some services may still let your device connect to the router, but block internet access if the service is suspended, capped or out of data.

This can look exactly like a Wi-Fi problem even though the Wi-Fi itself is working.

Step 9: Try a speed test when it starts working again

Once your internet is back online, run a speed test.

This helps you check whether the connection is properly restored or only partly working.

Look at:

• Download speed
• Upload speed
• Ping
• Jitter
• Loaded ping
• Bufferbloat

If the connection works but feels unstable, high ping, high jitter or poor loaded ping may explain why browsing, gaming or video calls still feel bad.

If only one device has no internet

If one phone, laptop or TV says connected without internet but other devices work, the internet line is probably fine.

Try these fixes:

• Restart the device
• Forget and reconnect to the Wi-Fi network
• Turn Wi-Fi off and on
• Turn airplane mode on and off
• Disable VPN
• Check date and time settings
• Update the device software
• Restart the router
• Try connecting to another Wi-Fi network
• On a laptop, update the Wi-Fi adapter driver

If the same device has problems on multiple Wi-Fi networks, the issue may be with that device.

If every device has no internet

If every device connects to Wi-Fi but nothing has internet, the problem is probably not your phone or laptop.

Try these steps:

• Restart the router
• Restart the fibre ONT if you have one
• Check the router and ONT lights
• Check cables and power plugs
• Check your ISP’s outage notices
• Check your account status
• Wait a few minutes after restarting
• Contact your ISP if the problem continues

If you have Ethernet, plug a laptop directly into the router and test again. If Ethernet also has no internet, the issue is likely with the router, ONT, ISP or line.

Is this a Wi-Fi problem or an internet problem?

A simple way to think about it:

If your device connects to the router but cannot reach websites, it may show “connected without internet”.

If only one room has problems, it may be weak Wi-Fi.

If only one device has problems, it may be that device.

If every device has problems, it may be the router, fibre ONT, ISP or line.

If Ethernet works but Wi-Fi does not, the problem is probably Wi-Fi.

If Ethernet and Wi-Fi both fail, the problem is probably not just Wi-Fi.

Why this happens in South African homes

In South Africa, many homes use fibre, LTE, 5G or fixed wireless internet. Each setup can fail in a slightly different way.

With fibre, your device may connect to the router, but the fibre ONT may have a line fault or your ISP may have a network issue.

With LTE or 5G, your router may be connected to Wi-Fi, but the mobile signal, tower congestion or data balance may be the issue.

With fixed wireless, bad weather, signal problems or tower issues can sometimes affect the connection.

This is why it helps to separate the Wi-Fi problem from the internet line problem before assuming your package is too slow.

When should you contact your ISP?

Contact your ISP if:

• Every device has no internet
• The router or ONT shows a fault light
• Restarting does not help
• Ethernet also has no internet
• Your account is active but the line is still down
• There is no known outage but the problem continues
• The issue keeps coming back

When you contact your ISP, tell them:

• Whether one device or all devices are affected
• Whether you restarted the router and ONT
• What the router or ONT lights show
• Whether Wi-Fi connects but internet does not work
• Whether Ethernet works
• When the issue started

This makes it easier for support to understand the problem.

Final thoughts

“Connected to Wi-Fi but no internet” does not always mean your Wi-Fi is broken.

It simply means your device has connected to the router, but something is stopping it from reaching the internet.

Start by checking whether other devices work. Then restart your router and ONT, check the lights, reconnect your device and check for ISP issues.

Once the connection is working again, use Lekker Speed Test to check your download speed, upload speed, ping, jitter and loaded ping.

Slow Wi-Fi is one of the most common internet problems at home. One minute everything works fine, and the next minute videos buffer, games lag, pages load slowly and video calls start freezing.

The frustrating part is that your internet package might not even be the real problem. Sometimes the fibre line or LTE connection is fine, but the Wi-Fi inside your home is letting you down.

This guide explains why your Wi-Fi may be slow, how to test it properly, and what you can do before blaming your ISP.

Quick answer

Your Wi-Fi may be slow because of weak signal, router placement, too many connected devices, interference, an old router, background downloads, poor coverage, or problems with your internet provider.

The easiest first step is to run a speed test close to your router, then test again in the room where the Wi-Fi feels slow. If the speed drops a lot as you move away from the router, the problem is probably your Wi-Fi signal and not necessarily your internet line.

Wi-Fi speed and internet speed are not always the same thing

Many people use “Wi-Fi” and “internet” as if they mean the same thing, but they are not exactly the same.

Your internet connection is the service coming into your home. This could be fibre, LTE, 5G, fixed wireless or another type of connection.

Your Wi-Fi is the wireless signal from your router to your phone, laptop, smart TV, console or other devices.

That means you can have a fast fibre package but still get slow Wi-Fi in some parts of your home.

For example, your fibre line might be capable of 100 Mbps, but your phone may only get 20 Mbps in the bedroom because the Wi-Fi signal has to pass through walls, cupboards, distance and other interference.

Common reasons your Wi-Fi is slow

There are a few common causes of slow Wi-Fi. Some are easy to fix, while others may need better equipment or help from your ISP.

1. You are too far from the router

Wi-Fi gets weaker the further you move away from the router. Walls, floors, furniture and appliances can also weaken the signal.

This is why your internet may feel fast in the lounge but slow in a bedroom, garage, outside room or upstairs area.

A weak Wi-Fi signal can cause slow downloads, buffering, lag, high ping and random disconnections.

Try running a speed test right next to your router. Then run another test in the room where the internet feels slow. If the result is much worse in that room, your Wi-Fi coverage is probably the problem.

2. Your router is in a bad position

Router placement matters more than many people think.

If your router is hidden behind a TV, inside a cupboard, under a desk or in the corner of the house, your Wi-Fi signal may struggle to reach every room.

For better Wi-Fi, place your router:

• In a central area of the home
• Off the floor
• Away from thick walls
• Away from microwaves and large metal objects
• Out in the open, not inside a cupboard

In many South African homes, the fibre ONT or router is installed wherever the cable enters the house. That spot is not always the best place for Wi-Fi coverage.

3. Too many devices are using the internet

Your Wi-Fi can feel slow when many devices are using the connection at the same time.

This can include:

• Phones
• Laptops
• Smart TVs
• Gaming consoles
• Security cameras
• Tablets
• Smart speakers
• Streaming boxes
• Background cloud backups

A single speed test may look fine when the house is quiet, but the connection can feel much slower when people are watching Netflix, playing online games, downloading updates or joining video calls at the same time.

If your Wi-Fi is slow, check what else is using the internet before upgrading your package.

4. Someone is downloading, updating or backing up files

Large downloads and uploads can make the whole connection feel slow.

Common examples include:

• Windows updates
• PlayStation, Xbox, Steam or Nintendo Switch downloads
• Phone cloud backups
• Google Drive or OneDrive syncing
• WhatsApp media backups
• Streaming in 4K
• CCTV uploads

Uploads can be especially painful. Even if your download speed looks decent, a heavy upload can cause lag, slow browsing, unstable video calls and high loaded ping.

This is one reason fast internet can still feel bad during real use.

5. Your router is old or not strong enough

Not all routers are equal.

Some older or basic routers struggle with faster fibre packages, many connected devices or larger homes. A router supplied years ago may still work, but it may not give you the best Wi-Fi performance.

An old router may cause:

• Slower Wi-Fi speeds
• Weak coverage
• Random drops
• Higher ping
• Poor performance when many devices are connected

If you have upgraded your internet package but still use an old router, the router may be the bottleneck.

6. Wi-Fi interference is affecting your signal

Wi-Fi uses radio signals, and those signals can be affected by interference.

Interference can come from:

• Other nearby Wi-Fi networks
• Microwaves
• Bluetooth devices
• Baby monitors
• Thick walls
• Metal objects
• Large appliances
• Poor router placement

This is especially common in flats, complexes and busy neighbourhoods where many routers are close together.

If your Wi-Fi is slow in the evening, it may be partly because more people nearby are using their own Wi-Fi networks at the same time.

7. You are connected to the wrong Wi-Fi band

Many routers have both 2.4 GHz and 5 GHz Wi-Fi.

2.4 GHz usually reaches further, but it is often slower and more crowded.

5 GHz is usually faster, but it does not travel as far through walls.

If you are close to the router, 5 GHz is usually better for speed. If you are far away, 2.4 GHz may be more stable but slower.

Some routers combine both bands into one Wi-Fi name, while others show separate names like “Home WiFi” and “Home WiFi 5G”.

If your speed is poor, check which Wi-Fi network your device is connected to.

8. Your internet package may be too slow for your household

Sometimes the Wi-Fi is not the only issue. Your internet package may simply be too slow for how your household uses the internet.

A small household that mainly browses and watches one stream at a time may be fine on a lower-speed package.

A busy household with streaming, gaming, remote work, video calls and many devices may need more speed.

As a rough guide:

• 10 Mbps can feel limited for a modern household
• 25 Mbps is usable for light streaming and browsing
• 50 Mbps is better for small families
• 100 Mbps or more is better for busy homes, gaming, 4K streaming and remote work

The right speed depends on how many people are online and what they are doing.

9. Your ISP or network may be having problems

If every device is slow, even close to the router, the problem may be with your internet connection or ISP.

Possible causes include:

• Fibre network issues
• LTE or 5G congestion
• ISP routing problems
• Area outages
• Damaged cables
• Faulty router or ONT
• Temporary service problems

Before contacting your ISP, test your speed close to the router and, if possible, test with an Ethernet cable. This gives you better information and helps show whether the problem is Wi-Fi or the actual internet line.

How to test if the problem is Wi-Fi or your internet line

The best way to troubleshoot slow Wi-Fi is to test in stages.

First, stand close to your router and run a speed test.

Then move to the room where the Wi-Fi feels slow and run another test.

Compare the results.

If the speed is good near the router but bad further away, your Wi-Fi coverage is probably the issue.

If the speed is bad even next to the router, the problem may be your router, internet package or ISP connection.

If possible, also test with an Ethernet cable plugged directly into the router. Ethernet is useful because it removes Wi-Fi signal problems from the test.

Easy fixes for slow Wi-Fi

Before upgrading your internet package, try these simple fixes:

• Restart your router
• Move your router to a better position
• Test closer to the router
• Disconnect devices you are not using
• Pause large downloads and uploads
• Use Ethernet for gaming, work calls or smart TVs
• Try the 5 GHz Wi-Fi network when close to the router
• Update your router firmware if available
• Replace an old or weak router
• Use a mesh Wi-Fi system for larger homes

A better router or mesh system can often make a bigger difference than upgrading to a faster internet package, especially if your main problem is poor Wi-Fi coverage.

Why your speed test may look fine but the internet still feels slow

A normal speed test usually measures download speed, upload speed, ping and sometimes jitter. These numbers are useful, but they do not always explain everything.

Your connection can still feel bad if:

• The Wi-Fi signal is weak in certain rooms
• Uploads are causing lag
• The router struggles with many devices
• The connection has high loaded ping
• Some apps or services are having their own issues
• Your device is the problem
• Your ISP has routing or congestion issues

This is why it helps to run more than one test. Test at different times, in different rooms, and on different devices.

When should you contact your ISP?

You should contact your ISP if:

• Speeds are poor even next to the router
• Ethernet speed is also much lower than expected
• The internet drops on all devices
• The router or ONT lights show a fault
• Your connection is slow at the same time every day
• Your package speed is much higher than what you are getting
• Restarting the router does not help

When you contact them, give them your test results, the time of the test, whether you used Wi-Fi or Ethernet, and whether the issue affects all devices or only one device.

This makes it easier for them to understand the problem.

Final thoughts

Slow Wi-Fi does not always mean your internet package is bad.

In many cases, the issue is router placement, weak signal, too many devices, interference, background downloads or an old router. The best way to find out is to test properly.

Run a speed test close to your router, then test again where the Wi-Fi feels slow. If the result changes a lot, your Wi-Fi coverage may need attention. If the result is poor everywhere, it may be time to check your router, internet package or ISP connection.

Use Lekker Speed Test to check your download speed, upload speed, ping, jitter and overall connection performance.

A good internet speed in South Africa depends on how many people use the connection and what they use it for.

A single person browsing, watching YouTube and using WhatsApp does not need the same speed as a family streaming 4K, gaming, working from home and backing up files to the cloud.

For many homes, 25–50 Mbps is a comfortable starting point. For families, gamers and heavy streaming households, 50–100 Mbps or higher is usually a better experience.

But speed is not everything. Ping, jitter, upload speed and bufferbloat can make a big difference to how your connection feels.

Quick answer

For basic use, 10–20 Mbps may be enough.

For everyday home use, 25–50 Mbps is usually more comfortable.

For families, gaming, 4K streaming and working from home, 50–100 Mbps or more is a better target.

For heavy users and large households, 100 Mbps or higher is recommended.

Internet speed guide by usage

Usage	Suggested speed
WhatsApp and basic browsing	5–10 Mbps
Email and social media	10–20 Mbps
HD streaming	20–50 Mbps
4K streaming	50 Mbps or higher
Online gaming	20 Mbps or higher with low ping
Video calls	20–50 Mbps with good upload speed
Work from home	25–100 Mbps
Busy family home	50–250 Mbps
Heavy downloads and creators	100–500+ Mbps

Why Mbps is not the only thing that matters

Most people focus on download speed, but your internet experience depends on more than Mbps.

You should also look at:

• Upload speed
• Ping
• Jitter
• Loaded ping
• Bufferbloat
• Wi-Fi signal quality

A 100 Mbps line with bad Wi-Fi can feel worse than a 50 Mbps line with a stable connection.

What speed do you need for streaming?

For streaming, download speed matters most.

General guide:

Streaming quality	Suggested speed
SD video	5–10 Mbps
HD video	10–25 Mbps
4K video	25–50 Mbps or higher

If more than one person is streaming at the same time, you need more speed.

What speed do you need for gaming?

Gaming does not usually need huge download speed while you are playing. What matters more is ping, jitter and stability.

For gaming, look for:

• Low ping
• Low jitter
• Stable connection
• Low bufferbloat
• Good router performance

Large game updates need high download speed, but actual online play depends more on responsiveness.

What speed do you need for working from home?

For working from home, you need a stable connection with enough download and upload speed.

Video calls, cloud files, emails, remote desktops and online tools all use your connection in different ways.

For one person working from home, 25–50 Mbps is usually comfortable. For multiple people working from home, 50–100 Mbps or more is better.

What speed does a family need?

A family home can use a lot of data at the same time.

For example:

• One person watching Netflix
• One person gaming
• One person on a video call
• Phones backing up photos
• Apps updating in the background

For a busy household, 50–100 Mbps is a sensible starting point. Heavy households may benefit from 100–250 Mbps or more.

Why your Wi-Fi may be slower than your fibre package

Your ISP package speed is not always the speed you get on Wi-Fi.

Wi-Fi can be affected by:

• Distance from the router
• Walls
• Interference
• Old routers
• Old devices
• Too many connected devices
• Poor router placement

If you pay for a fast fibre line but get poor Wi-Fi speeds, test with an Ethernet cable. This helps you see whether the problem is the line or the Wi-Fi.

Final thoughts

A good internet speed is not just the highest number you can get. It is the speed that works well for your home, devices and daily usage.

For many South African homes, 50–100 Mbps is a good target. For lighter users, less may be enough. For large households and heavy users, faster packages can make a real difference.

Run a speed test, check your download speed, upload speed, ping, jitter and bufferbloat, then compare the result with how your connection feels in real life.
