Here is some steps to take if you have problems with your FTTP service.

Status lights on the Openreach ONT

  • See Openreach FTTP ONT for more information about the lights and their meaning on the Openreach ONT.


I have no internet access

If you have no internet access at all on your FTTP service, then try these steps:

  • Check the Openreach ONT:-
    1. the Power light should be on - if not check power cable/switch etc
    2. the PON (Passive Optical Network) light should be on - if not, check the cables, try a power cycle of the ONT and get in touch.
    3. the LOS (Loss of service) light should be off - if not, check the cables, try a power cycle of the ONT and get in touch.
    4. the LAN or PORT1 light should be green - if not check your connection to your router, swap the cable
    5. More info on the ONT lights here: Openreach FTTP ONT

If lights are as they should be, then the Fibre and ONT should be working OK, time to:

  • Check your router:-
    1. Check the PPP username/password on the router, and restart the router just to be sure.
    2. Try a laptop/PC plugged in to the ONT instead of your router - set up a new network connection of type PPPoE and use your xxx@a login and password to connect: see PPPoE on a Computer for help in setting up PPPoE on a Computer.
    3. ...get in touch, email us a photo of the Openreach box and it's lights if possible.

Always worth running a test, even if LOS light is off - there could be a problem further upstream and Openreach may already be aware or we'll need to report a fault:

  • Run a test:-
    1. Our Control Page will allow you to run an 'End to End' test, this may if Openreach's systems detect a fault, in which case, do get in touch. eg:
      GTC_FTTP_SERVICE_1005 Possible fault in the Openreach network.
