You could also watch the DHCP exchange and see where it goes wrong (by comparing it to an exchange on your good Knoppix system).
hmm, I have just tried messing with ethereal a bit.. and am not too sure what I am doing with it but I have run a few captures through capture options on eth0 (and the psuedo-device), such as sticking in the mac address on the first ethernet address option and a few others to see if results came up.. and the results on everything I have run pretty much show no communication with the router, I see outgoing stuff like asking who is 192.168.0.1 with no replys (i get replys on this system just fine), and my dhcp discovers come back with offers on this system as well but nothing comes back on the problem system.. I have also run windows on the problem system just to make sure the ethernet still worked and it worked just fine, connected without any problem.. so the ethernet is fine, the router and modem are fine, the cords are fine.. the systems seem all fine as far as hardware.. just one connects when running knoppix and one does not.. and I guess I'm stuck there and don't know enough about linux OS's to figure out how to solve the problem....
