Thread: C2110 and Ubuntu

I have a Seimens C2110 modem, with Ubuntu installed. The modem works fine in XP but is a no go in Ubuntu. I have the following outputs after doing the ppoe config and giving the appropriate user name and password.
Plog:
ppo<--->eth0
Chap aunthetication failed
Check-Item Failed for NAS-Port
connection terminated

Output of:

I am not against Linux ,but whats the point in using such OS where we need to face lots of trouble even for doing simple task as mentioned above.
same can be done in windows within few seconds.

Which is the Ubuntu version you are using ?
