Download SN Margin has risen to 11.9 from around 6 after I disconnected the modem yesterday, so please perform an SNR reset.
Thanks

Have you been doing a lot of fiddling and several disconnects in a short time
If you haven't then a reason needs to be found otherwise it is unlikely that Plusnet will agree to do it specially if you had one
I suspect that your problem (from the linked thread) has come back
Edit - I got the time wrong

The last time I had the SN margin go up which was a couple of months ago PN performed a re-set which returned things to normal (requested through this forum).
Please try not to be condescending Oldjim.
Thanks

It does look like it's been caused by errors on the line, the quality is currently showing as Red (as opposed to amber or green) and the target SNR margin has indeed been raised to 12dB.
Resetting the SNR at this point would do more harm than good and would cause the line to retrain at a much lower speed. Is there anything that could be causing the errors? Router not in master socket, faulty filter, anything new added to the line?

It is connected to the master socket and nothing has been changed, it has all happened since I disconnected through the router to tidy the wiring up.
The line had been very stable and I'm sure before this it had stayed connected for twenty odd days.

Was that after the wiring had been tidied? Just wondering if something unforseen could have happened while that was going on.

@grahamholmes
What "tidying up" exactly have you done to the wiring? - That obviously constitutes "a lot of fiddling" in Jim's book
Assuming things haven't changed - can you confirm you are on 20CN, using the 582n and could you check the firmware version?
Does your 582n have a USB port and if so, are you using it?

I disconnected through the modem as I have done in the past.
The line seems stable now and I have had no disconnects for over 2 days.
20CN at exchange although 21CN is supposed to be coming soon any dates on this PN?
Router is TG582n
Software version 8.4.4.J
Not using a USB port

The estimated date at the moment is: 31/07/2013. This may be subject to change though.

If it's not disconnections it's going to be excessive errors. Could you post the errors counts (make sure you also give the connected time so we know how long they were over).

However there is one slightly worrying thing - the downstream attenuation is rather high compared to the downstream (normally the downstream is about half the upstream)
This may indicate a line fault or external interference but I am guessing here
