I have been using the full fibre 900 for more than a month now with speeds from 790 to 910 on speedtest. A few days now the speeds I get reach barely 250 testing against the same servers. I was also able to load 4k videos like a charm now it lags and is slow. Also, speedtest thinks I am located near Leicester, which I am not even close.
I called support they told me my line is fine and to check against fast.com which gave me 700 and then 300 they told my if it is 700 is fine. Well fast used to give me 1.4 Gbit in a 1Gbit line so not really trustworthy.
Are there any problems around Manchester area? Has anyone else experiencing anything like that?
