There are a few things that could cause a FTTP circuit to be slower than expected.

  1. A fault somewhere causing packetloss (this could be local to the customer's home network, or something further afield)
  2. Some miss-configuration or fault in the fibre provider's network (eg broken links causing congestion)

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

I have a 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 and some other 3rd party ones to check up and download speeds: https://speedtest.aa.net.uk https://www.fast.com- try tests at different times of the day as this can help track 'peak time congestion' - note - many http speed testers are not very good for testing 1G connections - to always take results with a pinch of salt
  2. Try a wired connection from your computer instead of WiFi to rule out any WiFi problems.
  3. Check/swap the cable between the ONT (The Openreach/CityFibre unit that the fibre connects to) 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.
  4. Ensure the router is capable of the speed of the circuit - eg, maybe you have a 1G service but an older router? - let us know the model you are using
  5. Check the CQM Graphs, via the Control Pages, to see if it is slow due to lots of traffic.
  6. Ask us about testing with 'iperf' - as this is generally better than http speed test websites.
  7. Try a laptop/PC plugged directly in to the ONT instead of using 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. see: PPPoE_on_a_Computer for more help on this.
  8. Try a different computer/device
  9. Try a power cycle of the Openreach/CityFibre ONT
  10. Check for packet loss - see below.
  11. ...get in touch.

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.

I may have packet loss

Packetloss can be seen in a number of ways, check the following to see if the location can be narrowed down to something specific:

  1. Ping your router's LAN IP - this will be the 'default gateway' your computers use - eg, could be something like 192.168.1.1 - if you have loss pinging your local router, check with a wired connection direct in to the router...
  2. Check the CQM Graphs on the A&A Control pages
  3. Ping the A&A endpoint IP: ping 81.187.81.187
  4. ping somewhere on the internet, eg ping 8.8.8.8 and ping bbc.co.uk

Slow CityFibre since migrating

We have seen CityFibre connections limited to say 500M when they have been migrated over to us. This could be due to the previous service being a 500M service and CityFibre's systems not updating the profile/bandwidth for the circuit. This can be tested with connecting a PC to the ONT and setting PPPoE_on_a_Computer - if around 500M is the maximum then let us know. The fix is for CityFibre to re-provision the ONT, which we can request.
