Do you have any extension sockets wired in?
Baffled at the moment.
As you have two lines with the same low original speed, and now this development, I don't see how it can be anything but external. I don't want the bill if you get one though. Are both lines supplied from one incoming cable - assuming it is overhead so you can see it?
Did you just report a noise on line problem?
The BT database line estimates are very often based on the historical performance of the line, basically as information perhaps for the next buyer/occupant. Notoriously inaccurate, as we see here. The attenuation is the measure of how much the signal has degraded between you and the exchange and is absolutely the prime determinant of the expected speed, give or take a bit. See
this graph. The average figure is because it includes results from lines like yours. My observations on these forums are that 40dB attenuation gets 6.5Mbps+ connections speed. Throughput is of course lower.
WHy did you delete the earlier post?
