This is what http://www.dslchecker.bt.com shows for my neighbour's address.
Telephone Number on Exchange is served by Cabinet 3
While I still fail to see the relevance of comparing lines with another person, what was your neighbours estimate Range A before Openreach changed anything?
As has already been pointed out, you are within your Range A estimate so there is no reason for BT to report a fault to Openreach for them to investigate.
It may well be that your neighbour was not within his Range A estimate and BT could therefore raise a fault with Openreach to investigate and as a result Openreach fixed the fault and restored his line to within its estimated range.
the speeds BT quote are connection speeds not download speeds from the speedtest as they can vary constantly over a 24 hour period
also your IP profile you refered to in an earlier post is set by your connection speed not the other way around so unless your connection speed increases your IP Profile will stay the same
Herein lies the nub of the question. We were both getting the same download speeds after we took out the new BT Infinity1 contract.
However, you say he obviously had a fault on his line but I don't (because I am connecting within the expected range for my line?)
His line was working, just like mine. The fact he is now getting 42 MB proves there was a problem (what do we mean by the word "fault"). Our houses are within a couple of hundred yards of each other, we are both connected to the same cabinet and we both have the same grotty old black round BT box bringing BT in to the house. Why everybody assumes I don't have a fault just because my line is actually working, I don't understand.
Anyway I think we have now exhausted the facts of the situation. Thanks everybody for your interest and help.
You seem to be missing the point. His line was maybe working, just like yours, but it could have been below the Range A estimate hence this would be classed as a fault because his line was not performing within the Range A. Yours is.
