I get a solid 39 down and 9.6 up on speedtests.
Been having a lot of disconnections recently, had openreach out a couple of weeks ago who could obviously find no fault, but reset my profile at the time and I was stable for about 12 hours. then it started disconnecting again. Worked from home one day last week and had it disconnecting every 30 minutes to an hour.
Only able to arrange a BT engineer for tomorrow due to work commitments and they better fix it this time as I went from the quoted very stable connection to one that is hit and miss and now showing:
Broadband Link Downstream Upstream
Connection Speed 27397 kbps 5000 kbps
Line Attenuation 17.3 dB 0.0 dB
Noise Margin 19.8 dB 20.20 dB
