I have just this week moved to fibre (well VDSL), from ADSL. On ADSL I was connecting at 18Mbs, speedtest at around fairly consistent 16Mbs.
I was moved in the early hours of Tuesday morning, since when speedtest results have been all over the place - sometimes 31Mbs, sometimes
Wow! 40GB/s is going some...
No, they are part of the crap backhaul you are connected to.
Which makes me wonder which ISP. I was allowed to leave the Post Office during my ADSL contract because of that problem.
If the service is with Vodafone you can leave in the 1st 30 days.

Sorry, the comma should be a dot..
If I remember correctly, Harry had trapped himself into staying with TalkTalk, so as not to lose his Tiscali email address.
Is that right Harry?

No, I swapped to Plusnet many moons ago.
In that case try the Plusnet forum. Traceroutes can well you which of the Plusnet gateways you are connected to. Sometimes they get clogged.
No showing 37.60Mbs, so taking overheads into account, that is now full speed.
can take a while for the plusnet end bandwidth setting to adjust to the home end ... give it a day.
Does this result show an IP profile that's close to your line rate, it would normally be 96.8%
You probably need to run the BT line checker to see your IP profile, but that gets set based on what the plusnet speed checker sees as your line rate above
It does now - I was quite concerned that the figures I was seeing were WORSE than my ADSL prior to the service swap.
The period of adaptation applies only to the last bit of the link - i.e. the xDSL connection performance. So generally if that is steady then chances are the problem is in the backhaul connection between your exchange and the ISP.
The exception to that might be if you are getting a high intermittent error rate on the local connection. In which case that may improve with time as the DSLAM learns to rate adapt down a bit for a slightly slower but more stable connection. If you router can show you the error rate on the line that can be instructive - you may be able to see periods with a large increase in errors detected. Sometimes forcing the router to retrain at that point can get better results.
