Spurious Packet Loss
 

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)


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??

Re: Spurious Packet Loss
 

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

:welcome: 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 ?????!?!?!?!

Re: Spurious Packet Loss
 

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. :nono: )

Re: Spurious Packet Loss
 

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.

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

Re: Spurious Packet Loss
 

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

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.

All part of the service here @ CF! :D

Re: Spurious Packet Loss
 

Thanks guys, not too bad now..... can I guess this was you, as I had to reboot the modem as it hung like a donkey ;)

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

Damn there goes my secret of what I did :D

EDIT: Apologies for the break in connection, modem wasn't being v cooperative.

Re: Spurious Packet Loss
 

Whoa, its happening again....

Ping statistics for 62.253.162.30:
Packets: Sent = 88, Received = 77, Lost = 11 (12% loss),
Approximate round trip times in milli-seconds:
Minimum = 11ms, Maximum = 62ms, Average = 17ms

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

Re: Spurious Packet Loss
 

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?
