Fix slow broadband speeds

Take a look at our Service Status page to see if there are any issues in your area that might be affecting your services. You can also visit My Connection to quickly test your connection and get SMS updates on any issues.

Use: 

• My Connection
• Service Status

These tools can quickly identify whether there's a fault on the network or an issue affecting your line. 

If an outage has been reported, no further troubleshooting is required until the network issue has been resolved. 

Run a broadband speed test and compare your result against the estimated speed provided when you joined TalkTalk. 

If your actual speed is close to your estimated speed, your broadband connection is generally performing as expected. 

If speeds are significantly lower than your estimate, continue with the steps below. 

Incorrect cabling or equipment setup can affect broadband performance. 

Check that: 

• You're using the original cables supplied with your router 
• All cables are connected securely 
• Your router is connected to the main phone socket 
• Any splitters or microfiltersare fitted correctly 

Find Your Main Phone Socket 

Your main phone socket is usually: 

• Near your front door 
• In a hallway 
• Close to where the external phone line enters your home 

Using the main socket helps deliver the most stable connection possible.

A simple restart often fixes temporary connection issues. 

1. Turn off your router at the mains 
2. Turn off your Openreach modem (if applicable) 
3. Wait 30 seconds 
4. Switch everything back on 

Allow a few minutes for the connection to re-establish and then run another speed test. 

Your broadband bandwidth is shared across all connected devices. 

If multiple people in your home are: 

• Streaming 
• Gaming 
• Downloading files 
• Joining video calls 

you may notice slower speeds on other devices. 

Try disconnecting everything except the device you're testing. 

If speeds improve, network congestion within your home is likely the cause. 

If this happens regularly, you may benefit from a faster package or additional Wi-Fi coverage products. 

Wi-Fi channels can become crowded, particularly in busy residential areas. 

If nearby routers are broadcasting on the same wireless channel as yours, this can cause: 

• Slower Wi-Fi speeds 
• Connection drops 
• Poor performance on certain devices 

If you use: 

• Wi-Fi Extender Kits 
• Wireless Powerline Adapters 

temporarily unplug them and test your broadband speed again. 

If performance improves, your adapters may need to be reconfigured. 

Follow the setup instructions provided with your device. 

Testing with a wired connection helps determine whether the issue is your broadband line or your Wi-Fi signal. 

1. Connect an Ethernet cable from your device to your router 
2. Run a speed test 
3. Compare the results 

If speeds improve significantly when wired, your broadband line is likely working correctly and the issue may be Wi-Fi related. 

Improve Your Wi-Fi Coverage 

If Wi-Fi coverage is the problem, consider: 

• Moving your router to a more open position 
• Reducing interference from other devices 
• Using a Wi-Fi Booster 
• Adding Total Home Wi-Fi 
• Using compatible eero mesh devices where available 

These solutions can help improve speeds in rooms further away from your router. 

Plugging your router into your test socket is a good way to find out if there's an issue with your external wiring; however, not all main phone sockets have one:

• Main phone sockets that have two ports or one port with a horizontal line across the front contain a test socket.
• Main phone sockets that have one port without a horizontal line don't have a test socket. If this sounds like yours, please skip this step and don't try to unscrew the faceplate.

Here’s how to connect your router to your test socket:

1. Carefully unscrew the main phone socket faceplate with a screwdriver. If it doesn't have screws, squeeze the sides of the faceplate to detach it
2. With the faceplate removed, you'll see the test socket inside. It looks similar to the phone port on the front of your main phone socket but without the sliding cover
3. Plug a microfilter into the test socket
4. Plug your router's broadband cable into the microfilter port labelled ADSL
5. Now run a speed test

If your speed improves whilst you're connected to your test socket, there could be a fault with your internal wiring. Slower or similar speeds could indicate a fault with the wiring outside of your home.

Testing from your test socket can help identify whether internal wiring is affecting your broadband speeds. 

If your master socket includes a test socket: 

1. Remove the front faceplate 
2. Connect a microfilter 
3. Connect your router directly 
4. Run a speed test
