Had fibre installed a few weeks ago and was pleased with the performance I was getting 73down 18up.
As per my luck we had a power cut (fire at a substation) I think today was the last day of the ten day training period.
Router came on and synced at
DSL Link Up: Down Rate=79987Kbps, Up Rate=19999Kbps; SNR Margin Down=19.6dB, Up=23.7dB
Didn't think anymore about it until I did a speed test tonight and for some reason only get 45-50mb down, according to BT my profile is set to 77, I have tried disconnecting from the internet and re-connecting, and I rebooted my HH5 once nothing seems to have made a difference.
Anything more I can do? What else could be the cause?
