Make a call on your landline

Broadband needs a working phone line. Check you can make a phone call and that there's no noise on the line. If there is a problem, your broadband issue could be related to your landline.

   Restart your Hub

      Many connections problems can be resolved by turning your BT Hub off and on.

  • Press the Power button on the back until all the lights go off and wait for 5 minutes.
  • Press the Power button again until all the lights come back on. It may take a few minutes for the lights to settle.

     If this doesn't work check the status of the lights (see below).

Check the lights on your BT Hub

The lights on your Hub give indicators about what the hub is doing and whether everything is working correctly.

If there are no lights, check the power cable is in firmly, and connected to the mains.

A steady blue means that the Hub is connected to your broadband. If you are still having problems try turning the device you are using - like a phone, tablet or laptop - off and on. 

If the light isn’t a steady blue there could be an issue, but there are things you can do to help resolve it.

Power cycle your modem

Fibre customers might have an Openreach modem installed. This is a white box that connects to your BT Hub.

We’ve found that many fibre connection issues can be resolved by power cycling the modem – turning it off and on again in a controlled way.

Try your test socket

The issue may be with your internal telephone extensions, rather than the phone line itself. One way to check this is by connecting your Hub to your test socket. 

The test socket is your main socket. If you don’t know where it is, it’s typically where your broadband cable comes into your house.
