Will to many errors cause my router to re-sync?

[craney13]

Evening everyone,

Sorry to ask what may seem a daft question, i have been monitoring my new router over the past day or so as i was getting lots of drop outs with the sagemcom and i have managed to get my stats up within telnet and im just curious to know if by having a lot of errors on the line does it cause the router to re sync?

I have been kinda baffled to why my old sagemcom would drop every 24hrs sky sent me a new d-link and that done the same so i thought id get myself a better router, i ended up getting the TP WD8960N which so far seems ok. I connect via homeplugs and have updated the firmware to the latest so im just monitoring the error count to see if this is causing the dropouts i kept seeing with the sagemcom, i thought it maybe over heating and resetting itself but when the d-link done the same i thought for 2 routers to have the same issue would just be unlucky. Sky have me on a 4.8mb profile with a max delay of 8 i wasn't sure if having me on such a high profile with a delay of 8 instead of 16 would maybe also be a cause as i know i only have a 3mb max line.

Anyway im using router stats to monitor the SNR during the day it sits pretty much at 7db but around early evening and as i write this its sitting at 6.6db it does seem to drop at night but im guessing this is normal?

I'll post my telnet stats below and if anyone could advise me in anyway id be so very grateful

Thanks so much and again sorry if my question sounds kinda stupid

To answer your question, too many errors over a short period can cause your router to resync. The total amount of errors does not mean much, it is how quickly they are being generated that is important.

The amount of errors you are showing under Total time, cover a much longer period than the time shown against it -

Total time = 1 days 10 hours 45 min 44 sec
FEC: 11552106 0
CRC: 2695 0
ES: 544 0
SES: 24 0
UAS: 37 37
LOS: 1 0
LOF: 9 0

I think these stats have the same glitch as those obtained from my router. ie, it will never show more than 2 days uptime. The actual time for these totals is probably nearer 7-8 days, maybe even more. You should reset the router to factory default and see if you can get rid of the total errors. This is an extract of the same section from my stats

Total time = 1 days 8 hours 45 min 47 sec
SF = 205427007
CRC = 17248
LOS = 14
LOF = 55
ES = 3861

This is actually for a period of 38 days, so I am not in the least worried about the errors shown,.

Thanks for that isitme my router has been up for 5 days now and this is what my stats are showing

Since Link time = 5 days 3 hours 16 min 39 sec
FEC: 562145 0
CRC: 3018 0
ES: 584 0
SES: 27 0
UAS: 0 0
LOS: 0 0
LOF: 0 0

As for the glitch you mention i think you are right this is what my stats are giving me for the total time

Total time = 1 days 4 hours 7 min 31 sec
FEC: 18203589 0
CRC: 5651 0
ES: 1102 0
SES: 49 0
UAS: 29 29
LOS: 2 0
LOF: 18 0

This includes maybe 3 router re syncs so the total time hasn't been cleared by a factory reset so i reckon over all with my current 5 day link time the above shows maybe 10 days worth or stats.

Would upping the max delay set on my line from 8ms to 16ms perhaps reduce the error count or am i worrying about nothing here really? Its just at the mo my SNR is showing 6.7db and sometimes goes as low as 6.2db in the later part of the evening and i was just worried of another drop out

Thanks again for your help mate

If that is all it is falling, you have nothing to worry about. That's a pretty stable line compared to some.
