My Openreach modem’s DSL light is off. What should I do?

Broadband isn't active on your telephone line or the signal is not reaching your modem. To troubleshoot:

  1. Check if anything, such as network maintenance, is affecting internet performance by viewing BT Service Status .
  2. Check that the DSL cable is plugged into the DSL socket of the Openreach modem.
  3. Check that the DSL cable is plugged into the data connection on your master phone socket or data extension socket.
  4. If your Openreach modem is connected to a data extension socket, away from your master phone socket, check whether the data extension cable is damaged.
  5. Reset the modem. Press and hold down the Reset button on the back of the modem for five seconds. Then, release the button and wait a few minutes for the Power light to switch on.
  6. If the DSL light is still off, disconnect the power cable, wait a few moments, reconnect the power cable and wait a few more minutes for the Power light to switch on.
  7. If the modem’s DSL light is still off, restart your Fibre Hub. Press and release the Reset button on the back of the Fibre Hub. Wait a few minutes for the Fibre Hub’s PowerBroadband, and Internet lights to glow a steady green.
    If the Fibre Hub’s PowerBroadband, and Internet lights do not glow a steady green, please find more information on this on our BT Business Community.
  8. If the modem’s DSL light is still off, please contact us. Please have your computer turned on when you call.
