We had a sudden line fault last thursday. A BT engineer came out on monday and after a few hours investigation told us that the fault was in the exchange. Tuesday morning our connection was back up but our SNR margin has been hiked up to 15dB, presumably from all the disconnects during the fault.
Anyway, we used to get sync speeds over 6000 but now thats down to less than 4000. At the moment its 3008.
I've been told that the DSL connection must stay up for 14 days for BT to automatically reduce the SNR margin, but I have doubts as to whether thats possible for a consumer router, especially after some bittorrent.
I read somewhere that its possible to get BT to reset the profile after a line fault. Is that right?
