Comment 2 for bug 339882

Sergiu, I have also this problem and I am very angry about it. I've been working with Kubuntu since Gutsy Gibbon and was very satisfied with that. But since I have upgraded from Intrepid to Jaunty I can't reach internet, because someone have canceled the option to proceed alternative by using terminal comand pppoeconf. The result is following:

dietmar@dietmar-desktop:~$ sudo pppoeconf
[sudo] password for dietmar:
Plugin rp-pppoe.so loaded.
RP-PPPoE plugin version 3.8p compiled against pppd 2.4.5
dietmar@dietmar-desktop:~$ ifconfig pppO

So, my opinion is, you have no chance for solve this problem untill the MOTU regognized this. I have "tilt" the jaunty and have reinstalled the intrepid. There is also this damned network-manager, but you can work with the terminal.
