An old story from what I see here: flooded - damp mircofilter - bad connection - profile goes to 135 Kbps.
Replaced filter - connection back to 2.5 Kbps - profile stays 135 Kbps - call BT to tell them I don't want to wait 3 days with unuseable connection (I need to use VPN for work). Now, 36 hours later, about 4 of those spent having inane and repetitive conversations with various people following useless support scripts, I end up being told that the problem is nothing to do with the profile*, but is because interleaving was switched on, that it has now been switched off, that the speed will be back within 24 hours and that the incident is now closed. My understanding (such as it is) is that interleaving would allow a faster rate in exchange for a increased latency, and could not possibly be responsible for the 135Kbps limitation. If that is so, what I have been told is complete nonsense. Am I missing something? I downloaded DMT, and that shows me that interleaving is still on, so at least that part of it was wrong. I also understand that the 3 day wait can be overriden by BT, although they are reluctant to do it. Is that right? I have written an extremely nasty complaint to BT, but I could do with a check on these two points before I send it, if anyone out there feels like providing it.
*actually, from the conversations, one would have to conclude that either they had never heard of profiles, or that they have been expressly forbidden from acknowledging their existence.
PS - I am so glad I discovered this site/forum. It has just saved me from lapsing into totally insane rage.
