Hey Billion Fans,

These are my stats after first plugging in my router hour and 16 min ago do my error rates look high for short amount of up time? It looks the es and crc errors are going up at same rate.

I gather from the webgui i'm on the latest firmware 2.52.d10.

There doesn't seem to be an issue there from my perspective. 22 ES/ CRC's is pretty low for that time period I'd suggest.

One thing I do note from your stats is the downstream SNR. That seems quite low at 3.4dB. I'd expect it to be much closer to 6dB, which is the ISP default target if I recall.
That aside, if the line's stable and you're not experiencing any issues, I'd sit back and enjoy it.

Well that's the thing Paul the connection doesn't seem stable as when I woke up at 7 this morning I saw the connection resnyced about an hour earlier, mabye the fast growing number of FEC caused this do you think? When I looked yesterday it looked like I was getting thousands of fec errors a minute. I did look at the ES errors at 11pm last night before i went to bed after 4 hours of uptime and there was 94 would you say that was an acceptable rate?

I think it's CRC's that the DLM is looking at, and could cause a re-sync if excessive. FEC's are corrected errors, so have been caught and 'fixed'. At least that's my understanding.

I wouldn't say 94 ES errors over that time period is a lot but, it's not a low number either. It does sound like there are some inconsistencies on your line though, so it would be worth monitoring it with DSLStats.

Try using the attached firmware and see if the error count drops
