Line trained but stuck at 12dB SNRM, what do I do now?
Hi clanla
From what you have reported reminds me of a period I went through earlier this month after I requested my upload to be uncapped. I believe that the DLM kicked in and has tried to find a stable setup (I could be wrong, but I'm sure the knowledgeable members will put me straight!).
Did you make any observations on the download CRC errors?
I thought I was doing well maxing out the bandwidth but the CRC errors were coming in at around 4000/day and the DLM kicked in. I'm currently settled at around 11dB with CRC clocking in at 123/day though the bandwidth has been reduced somewhat, but my connection has been solid for 19 days (touch wood
)
Fingers crossed that you don't have a problem

Hi Colin,
yes, stats are just the job and errors was what I had in mind, and there's a heck of a lot there, the SES aren't too nice - but there again you did say that you had a thunderstorm and every lightning flash can add 1000's of CRC, ES and a few SES, but slightly intriguing is the LOS - didn't expect that to be as high - but there again during a storm there could be attempts to resync that don't succeed and you may only see several as one resync. You mentioned one resync at 900 which implies a lot of static still there when that resync was successful.
I don't remember watching my LOS figures last time I was looking at my stats during a thunderstorm (some long time ago), so I don't recall what happened to them - I just watched the huge bursts of CRC/ESs and on the second loss of sync it got switched off - you know what happens when you get too many resyncs in a short period and on 20CN the consequences are a real pain. So because of that I don't think one can interpret too much from those error figures
These days if I get a very large burst of errors with an approaching storm, I just tend to switch off. Apart from which I hate looking a a large value of CRC/ES errors (that were just due to one incident)
However, the stats do show something of concern, the US SNRM - I would have expected it to be a bit higher. Has it always been around that level, I couldn't find any earlier stats to compare? Suggests some background noise, but may be nothing to worry about if all else is right.
Are you still running the v4, a bits/tone might reveal something further? Can't remember what you decided about the LInksys other than it seemed more susceptible to noise (similarly the v3).
