Fix a dropping broadband connection
Why your broadband keeps dropping out - and how to fix it?
If your broadband keeps dropping out, your Wi-Fi keeps disconnecting, or your internet connection is cutting out unexpectedly, don't worry. Most connection issues can be fixed in just a few minutes.
The first thing we recommend is running a TalkTalk Line Health Check. It'll quickly identify any known faults affecting your service and point you towards the best next step.
If your connection is still dropping after a health check, follow the troubleshooting steps below. We'll help you work through the most common causes, from router issues and Wi-Fi interference to device problems and local outages.
New to TalkTalk or just upgraded to Fibre?
If you've recently joined TalkTalk or upgraded your package, your connection may still be settling in.
During the first few days, your line can go through a stabilisation period while it finds the best settings for your connection. You may notice occasional drops in speed or connection while this happens.
If you've only recently activated or upgraded your service, keep your router switched on and connected where possible so your line can settle successfully.
TalkTalk App customer?
As a TalkTalk app customer, you can use the app to keep track of your service and run troubleshooting checks when something doesn't seem right.
It's one of the quickest ways to understand whether there's a known issue affecting your connection.
Got Full Fibre?
If you've got Full Fibre, your service doesn't rely on the traditional phone network, which means it can be more reliable and less affected by some common broadband issues.
If your Full Fibre connection is dropping, work through the troubleshooting steps below. They're designed to help identify whether the issue is with your Wi-Fi signal, equipment, devices or the service itself.
Essential troubleshooting steps
If your internet keeps dropping out, this should always be your first port of call.
A restart clears temporary errors and refreshes your connection to the network. We know it sounds basic, but it's often the quickest fix for intermittent broadband issues.
How to do it
- Switch your router off
- Wait at least 30 seconds
- Turn it back on
- Allow a few minutes for the connection to fully reconnect
Once all lights have settled, check whether your connection has improved.
It can be tempting to turn your router off when you're having problems, but frequent power cycling can actually make things worse.
Your router and broadband line work best when they're left connected. Keeping your router switched on allows the network to maintain a stable connection and complete any updates or line optimisation processes.
If you've recently joined TalkTalk or upgraded to fibre, this is particularly important.
Loose cables are a surprisingly common cause of broadband cutting out.
What to check
- Make sure all cables are securely connected
- Check the power cable is firmly plugged into the router
- Ensure your broadband cable is fully inserted
- Look for signs of damage, kinks or wear
- If you're using a phone socket, check it's connected to your main socket
If you're unsure which socket should be used, visit our guide to the master socket guide.
Sometimes the problem isn't your broadband connection at all.
Check whether the issue affects:
- One device only
- Several devices
- Wired devices
- Wireless devices
If only one device keeps disconnecting, try:
- Restarting the device
- Updating its software
- Forgetting and reconnecting to Wi-Fi
- Testing another network connection
This can help determine whether the issue is device-related rather than broadband-related.
A weak Wi-Fi signal can make it seem like your broadband is dropping when the real issue is wireless coverage.
Router placement is key
For the best performance:
- Place your router in an open space
- Keep it off the floor
- Position it centrally within your home where possible
- Avoid cupboards, cabinets and enclosed spaces
Minimise interference
Many everyday household items can interfere with Wi-Fi signals, including:
- Microwave ovens
- Baby monitors
- Wireless speakers
- Cordless phones
- Large metal objects
Moving your router away from these items can improve Wi-Fi stability.

Testing different devices can quickly help identify where the problem lies.
Ask yourself:
- Does the issue happen on every device?
- Is it affecting phones but not laptops?
- Does it happen only in certain rooms?
If multiple devices experience the same issue, the problem is more likely related to your broadband service, router or Wi-Fi environment.
If only one device is affected, focus your troubleshooting there first.
In simple terms, bandwidth is the amount of internet capacity available in your home. Modern homes often have dozens of connected devices competing for bandwidth.
Activities such as:
- 4K streaming
- Online gaming
- Large downloads
- Video conferencing
- Cloud backups
can all place increased demand on your connection.
How to manage
Try:
- Pausing large downloads.
- Closing unused applications.
- Disconnecting devices you're not using.
- Scheduling backups outside peak usage times.
If your connection struggles regularly during busy periods, it may be worth reviewing whether your current package meets your household's needs.
Sometimes the problem isn't inside your home.
Planned maintenance, local issues or network faults can affect broadband services in your area.
How to check
Visit the TalkTalk service status page or run a Line Health Check to see whether there's a known issue affecting your service.

FAQs
Why does my Wi-Fi keep dropping out unexpectedly?
The most common causes are Wi-Fi interference, router issues, faulty cables, local service outages or high demand from multiple connected devices.
What is the first thing I should do if my broadband keeps disconnecting?
Run a TalkTalk Line Health Check and restart your router. These two steps resolve many common connectivity issues.
How often should I restart my router?
Only when troubleshooting an issue. Frequent restarts aren't usually necessary and keeping your router switched on helps maintain a stable connection.
Can other devices interfere with my Wi-Fi signal?
Yes. Devices such as microwaves, baby monitors and cordless phones can affect Wi-Fi performance if they're located close to your router.
Why is my new TalkTalk fibre connection dropping out?
