Something happened to my (ADSL Max) line a couple of weeks ago, used to have ~2.5Mb/s sync stable (2Mb speedtest throughput after BT's IPProfiles screwed me over) now It's like this.
Attenuation hasn't changed, so seems like there's interference somewhere - even with a 14.5dB noise margin I've got a hell of a lot of errors. I used to be able to run on Fastpath but had to switch over to Interleave to stop the line dropping every few mins.
Any suggestions? I'm using an XTE-2005 filtered faceplate, Cisco 877 adsl router, and haven't made any internal wiring or phone changes.
