Previously Stable 10Mbps line syncs at 63kbps. Help Please!

[Cybertron436]

Okay so this all started 3 weeks ago when my 10Mbps ADSL that had great SNR and Attenuation (SNR 27 on 10Mbps and Att at about 15) dropped to 6Mbps, I wrote it off as ASSIA being annoying and accepted it, but now my line is starting to sync at 812kbps and even as low as 63kbps and I have no idea why. Telkom was in about a month ago and messed around with soem fibre optic cables in the back and I don't know if that could be the cause. These are my current line stats, I live in a VDSL enabled area and am about 500 metres from my exchange.

Your attenuation looks like you are VERY far away from the exchange... meaning that the cable is most likely at fault.

Replace your telephone cable from wall to modem first and check, then try another modem.
Failing that, the line from the wall to the exchange is damaged and Telkom must replace...

Goodluck!

Your attenuation and noise margins suggest a line fault. ASSIA might be exacerbating the problem, but is not the primary cause. Does your voice line work?

Maybe replace your pots filter.

My voice line works but my att and SNR have all returned to much more normal levels and my speed has changed. SNR above 20 and att below 30.
