Spurious Packet Loss

ntangle · 23-11-2004, 22:47

I have been having loads of problems with BB for about 2 years, the main problem is losing the downstream component (Have a SB4100 CM)

0411091121477-InformationH501.2HFC: Shutting Downstream Down 0411091121472-AlertT507.0Received Async Error Range Failed 0411091121303-CriticalH501.8HFC: T4 Timer Expired 0411091121307-InformationH501.11HFC:Unable to recover FEC lock 0411091121273-CriticalH501.16HFC: FEC LOCK recovery failed

This seemed to get resolved, now I am suffering from wild packet loss 30-40% but this evening after rebooting the CM I am only suffering from 5% (pinging glfd-t2core-a-ge-wan61.inet.ntl.com). I have spoken to the faults line and they say it is the cable modem at fault. It is very irregular. Any idea's anyone??

Why don't you just get ntl to replace the modem?

to the site btw.

Cos I don't think it is the modem, Transco have had the road up next to the 'green box' for a week, and were mucking around today when it went funny. Just wondering if it is something else ?????!?!?!?!

Aha.....

Well-either way ntl need to come out, & if they discover it's Transco's fault then that's for them to take up with Transco & bill them for repairing the damage.

Either way, you shouldn't lose out.

(And don't let ntl try to tell you that you have to take it up with Transco.

ntangle, please send me your public IP address and I will check how your modem looks from the ntl end (open a DOS prompt, in WinXP Start-Run-CMD then type ipconfig and that should give you your IP address, unless you are behind a router in which case the router's WAN IP address is what I need).

Thanks.

Thanks.

Send it in a PM (Private Message), rather than post your I.P on a public forum!

This is true, these IPs are far more valuable to my customers when only I know them

Seriously yes PM me the information I'll check it out.

Just to reassure you I have no way of tying your IP address to who you are, where you live, etc, you'll literally be just a set of numbers on a screen to me incase you're worried about the privacy aspect

Neil has given me your details and your issue should now be resolved. Ta.

pinging the ntlworld.com website I get the following stats......
Ping statistics for 62.253.162.30:
Packets: Sent = 125, Received = 123, Lost = 2 (1% loss),
Approximate round trip times in milli-seconds:
Minimum = 11ms, Maximum = 60ms, Average = 18ms

kind of looks a lot better

Thanks again

what can the problem be? again?????

dragon · 08-12-2004, 22:44

hmm maybe those packets just have a poor sence of direction...

seriously though maybe a router or something is playing up and dropping a few packets. maybe someone from ntl could run some diagnostics or somthing?
