Telstra Bigpond connection via Sierra aircard 880U
 
Hi, I have had this modem working for months without any problems now (well, at least after finding out how to get it started), But the connection recently decided to stop working. The modem still dials up as it is supposed to, but I cannot access any web pages (or do anything else on the internet). The modem is flashing as it is supposed to.

This occurs regardless of which distribution I use (Ubuntu, Linux Mint, OpenSUSE), whether I use kppp, network manager or KInternet, and is the same for different web browsers. Everything works normaly in Windows however (Which is why I can post this)

Here is a sample of what happens in the system log when I try to log in using Ubuntu and kppp (My usual method)

Hi, I had similar probs with my vodafone connection and found that the nameserver was not found.

I use the same 10.64.64.64 internal addresses you mentioned above, with 10.11.12.13 etc.

I found that resolv.conf was changing the dns addresses each time I rebooted the machine.

I then re-set the /etc/resolv.conf manually and turned off resolvconf service from starting.

Quote:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 202.135.30.4
nameserver 203.2.193.67
nameserver 192.168.0.0
search GlennsPref.net
was being replaced by...

nameserver 127.0.0.1

or

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 10.11.12.13
nameserver 10.11.12.14
nameserver 192.168.0.0
search GlennsPref.net

Check yours and see...

Regards, Glenn

I got my address settings from the windows settings, as I can not access the modem like I would with a router.

Also, the 10.11.12.13 addresses are wins, and not the actual dns addresses(i think, works for me anyway).

Thanks!
 
GlennsPref, you're a genius. Rather than modifying resolv.conf however, I just specified some DNS addresses in kppp. This seems to have done the trick.

I got it working by simply following the instructions here on the whirlpool net au site. Unfortunately I can't post the link here because I'm not allowed due to the spam policy :(

on Telstra.internet 3g 880U modem using kppp on Kubuntu 8.04

GlennsPref 02-06-2009 05:36 PM

You can post a link and much more after you introduce yourself.

Glad to see you got it going.

I might have to try the kppp dns too.

I still have a bunch of services turned off to facilitate my hack....

Cheers, Glenn
