Ubuntu 12.10 Modem Connected but no internet
I was previously running ubuntu 12.04 and upgraded to ubuntu 12.10. Previously on 12.04 when I removed my wired ethernet connection and plugged in my 3G modem I was immediately able to browse the internet. However now on 12.10 I am unable to do so, even though the modem shows that it is connected when I go to Firefox or Chrome it displays an error. In order for my 3G to work I need to restart my machine (without the ethernet cable plugged in) and then plug in the 3G modem. It then works.
Please help or advise what I can do.
Thanks.

I was (and am) having a similar problem while connecting to the Internet using my MTS MBlaze (India) dongle which is a ZTE device. I am using Kubuntu 12.10.
A while back I was only able to connect to the device from Network Manager applet, but a ping to any address including 8.8.8.8 resulted in "Network is unreachable". I figured out this could primarily be because of my host not being able to connect to MTS gateway.
'ifconfig' shows something similar to the following:
ppp0 Link encap:Point-to-Point Protocol
inet addr:180.215.149.123 P-t-P:10.228.10.5 Mask:255.255.255.25
I used the 'route' command to manually add the gateway address (P-t-P in above ifconfig output) as follows:
sudo route add default gw 10.228.10.5
And voila, I was able to ping again, even to google.com (as dongle devices auto configure DNS servers as well); there is no need to change /etc/resolv.conf at all.
Now I need to figure out how to automate this. Any help most welcome.
