Problems with broadband?
If you think you've got a problem with your Broadband connection or speed
Troubleshoot your BT Broadband connection
 

Important
We can only check the line if it's not currently being used. This includes:
    - Internet access
    - Phone calls using a standard or VoIP phone
    - Fax
    - Broadband services e.g. BT Vision
You'll need to run this check using a PC connected to a different line and ensure that the line you wish to check is unused.
If another line is not available, we can help you to check things out using our Troubleshooting Guide
