The Broadband light is flashing orange then pink/purple

This happens when your Hub is establishing the fastest, most reliable connection for your broadband line.

If the Broadband light occasionally flashes orange then pink/purple between periods of steady blue, please wait until it glows a steady blue. This can take up to 24 hours.

If you're new to BT Broadband then you need to know that we'll be remotely testing your line for ten days after your activation. So you may notice your Broadband light occasionally goes off and then flashes, interrupting your broadband service. This is normal and things should settle down after ten days.

If your Broadband light is constantly flashing orange then pink/purple, please try the following:

  1. Restart your Hub by pressing and releasing the Restart button on the back of the Hub.

    If you are a BT Infinity for business customer check the cable is connected between the red Infinity Port and LAN1 on the Openreach modem. Remove and replace if necessary.

    If your Hub is not connected by a red Ethernet cable to an Openreach modem then:
  2. Check that any extension socket you may be using has an ADSL filter fitted.
  3. If you are using an extension lead or extension socket, plug the ADSL filter and Hub directly into the main phone socket.
  4. Unplug any other telephone devices (such as telephones, fax machines, digital TV boxes etc.), leaving only your Hub and its ADSL filter plugged in.
  5. If the Broadband light is now a steady blue, either your wiring or an ADSL filter might be faulty. Reconnect each ADSL filter and telephone in turn, checking the Broadband light, to find out if one of them is faulty. Also make sure that every device in use is using an ADSL filter. If you've moved your Hub, try moving it back.
  6. If your Broadband light continues to flash, there may be a fault or interference on your line. Contact us for technical support.

Broadband light is off

If you've just got broadband, make sure it is after midnight on your broadband activation day. If not, please wait a little longer.

If your BT Business Hub 3 is connected to an Openreach modem (the Ethernet cable connecting them will be red):

  1. Check that the red Ethernet cable is connected to the Openreach modem and the red BT Infinity port of your Hub 3.
  2. Check the Openreach modem is active and working.
  3. If the cable and modem are OK, contact us for technical support.

If you are not connected to an Openreach modem:

  1. Check that the broadband cable (grey ends) is correctly inserted into your Hub's Broadband socket (grey).
  2. Check that the other end of the broadband cable is correctly inserted into the ADSL filter's DSL socket, and that the filter is correctly plugged into your phone socket.
  3. Plug a telephone into the Phone socket on the ADSL filter and listen for a dial tone.

If there's no dial tone:

  • Try swapping the ADSL filter or temporarily plugging your phone directly into the telephone socket. If there's a dial tone, this indicates a faulty ADSL filter.
  • If you're using an extension socket or extension lead, try plugging the ADSL filter directly into the main phone socket and listen again.
  • If there is now a dial tone at the main socket, but not at the extension, this indicates the extension lead, wiring or socket is faulty.
  • If there's no dial tone at the main socket, this could indicate a problem with your telephone line. You can report and track telephone line faults at www.bt.com/faults.

If there is a dial tone:

  • If you're using an extension lead or extension socket, plug the ADSL filter and Hub directly into the main socket.
  • Unplug any other telephone devices (such as telephones, fax machines, leaving only your Hub and its ADSL filter connected.
  • If the broadband light is now a steady blue, either your wiring or an ADSL filter may be faulty. Reconnect each ADSL filter and telephone device in turn checking the broadband light, to find out if one is faulty. Remember that every telephone device that's plugged in needs to be connected using an ADSL filter.
  • If the broadband light still does not come on contact us for technical support.
