I used to be able to get online with Knoppix, with no problems. First I started having problems when I used the "myconfig" cheat code, now I can't get online AT ALL with either version 3.7 or 5.0.1, even though I've deleted my configuration file from my hard drive.

I've run ifconfig and lspci, and here are the results.

RESULTS OF lspci -v

The modem works fine with other Linux live-CD distros and with Windows, so this is a Knoppix-specific problem. Can somebody please explain what I need to do, in order to be able to get Knoppix working properly with my modem again? I've searched the internet till my fingers are numb, read books on Linux and recently bought a book on Knoppix, and none of these resources tells how to configure a cable modem connected via an Ethernet cable (since Knoppix has apparently decided it no longer knows how to do this automatically).

Any help would be appreciated very much.
