Status lights on the Openreach ONT

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

No connection

• 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

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.

Slow FTTP connection

If your FTTP service is slow, eg a speed test is not reporting expected speeds, then try these:

1. Use our speed test to check up and download speeds: https://speedtest.aa.net.uk - try tests at different times of the day as this can help track 'peak time congestion'
2. Try a wired connection from your computer instead of WiFi to rule out any WiFi problems.
3. Try a different computer/device
4. Ensure the router is capable of the speed of the circuit - eg, maybe you have a 1G service but an older router?
5. Check/swap the cable between the Openreach ONT and your router - ensure it's a 8-wire CAT5 or CAT6 cable - not one with 4 wires as these will run at 100M and not 1G.
6. Try a power cycle of the ONT.
7. Check the CQM Graphs, via the Control Pages, to see if it is slow due to lots of traffic.
8. 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, and run a speed test.
