Anybody have any idea why my SNRM has reduced down to 4dB when it normally sits at 6dB and has lowered my sync speed down to around 44. Attainable is still at 48 as i have not done a reboot on the modem yet.Could this be crosstalk or do I take a chance and reboot modem.
This isn't quite what MDWS says...
It sees that your attainable was 48 abut a week ago, before the last resync - but has now dropped to 44.
MDWS also shows that your SNRM rose just before your last resync, by about 1.5dB, which allowed your speed to increase from 47 to 48.
The line then ran with a normal 6dB SNRM for the next 8 hours until ... MDWS stopped getting statistics from you.
When statistics start up again, about 11 hours later, the SNRM has dropped, by the same amount again - 1.5dB.
It looks like @roseway is correct - the change in SNRM is happening because of changes to crosstalk from another subscriber. First they turned off, which allowed you to resync at a higher speed, then they turned on, which has dropped your SNRM.
ES and SES rates haven't changed much over the last couple of months.
Apart from a proper line fault around August time last year I have had no real problems and had the billion for just over 18 month's. When SNRM has dropped in the past it has always recovered with in a few hours. I have an old HG612 which is unlocked could if be worth trying that and run it for a couple of days to eliminate an issue with the billion
I'll just add a reminder that you don't need to see much in the way of "work" to suffer more crosstalk. There just needs to be a new FTTC subscriber somewhere in the neighbourhood - very much business as usual.
Don't assume that anything has gone wrong anywhere.
