(Newer) Openreach single port ONT

Lights on the Openreach ONT

• We have a page about the lights and their meaning on the Openreach ONT: Openreach_FTTP_ONT

No connection

• Check the Openreach ONT:-
  • the Power light should be on - if not check power cable/switch etc
  • the PON (Passive Optical Network) light should be on - if not, try a power cycle of the ONT and get in touch.
  • the LOS (Loss of service) light should be off - if not, try a power cycle of the ONT and get in touch.
  • 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:
  • Try a laptop 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
  • Check the PPP username/password on the router, and restart the router just to be sure.
  • ...get in touch

Slow connection

• 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
• Use our speed test to check up and download speeds: https://speedtest.aa.net.uk
• Try a power cycle of the ONT
• Check the CQM Graphs, via the Control Pages, to see if it is slow due to lots of traffic
• Try a laptop 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.
