Deteriorating Noise Margin

Just posted this in bulldog's forums - wondered if anyone here may have some advice:

My internet connection has become very bad recently, and Ive just checked my noise margin vales (which were low at 11 dB to start with), and they have dropped to a noise margin of 6.5 to 7dB!!

I have removed the face plate of the main socket in our flat (we only have one) and plugged the router straight into the one inside. The values dont improve :(.
What can be done? Its getting really daft now, its been alright for a year and a half - but now its terrible :( . My speeds have been comparable to 512 for the past few days now, despite being on an 8 meg contract.

What can I expect? Further deterioration? A solution perhaps?
 
I'm synched at 3Mbs and get a lot of errors :S

Fast Path CRC Error
near end: 26806 <-- going up by about 50 a second
far end: 12

Fast Path HEC Error
near end: 4938
far end: 4938
both going up by 10ish a second

that mean anything to anyone? Thats from this morning.

LOL a speedtest gave my downstream connection as slower than my upstream :( I'm slowly reverting back to 56kps modem speeds. NOOOOOOOOO

I spoke to them this morning, and they said they would make some changes to hopefully make the line more stable. Not noticed anything yet, noise margin still the same and the errors are still racking up just the same. Dont know when they were perform these changes - I was under the impression it was fairly immediate :confused:

46dB would seem to imply somewhere in the realms of 5km of cable, assuming it's ordinary copper with no dodgy joints etc.
First path should be getting Bulldog to up the target SNR margin (if that's not what they're doing), then take it from there.
I believe thats what the guy said they would do. Though so far nothing has changed... dunno how long before they will fiddle with that kinda thing :confused:
