Hi,
I'm not expert both of wireless networking and Knoppix/Linux.
I'm getting crazy trying to setup internet connection with my wireless card Intel Wireless Pro/3945ABG and last Knoppix 5.3.1 DVD.
It seems card is detected, but I'm not able to get IP address from my router with DCHP enabled. And still, I'm not able to ping any host even if I try to disable DHCP. I tried both with encryption enabled and disabled. I also tried to ndiswrapper windows drivers, but result was the same.
Below you can find printout of commands iwconfig, ifconfig (in case of attempt with DHCP enabled), and lsmod.

Please, help me! Thanks!

I have a 3945ABG and have been generally pleased with the compat-wireless project which provides the iwl3945 module. Intel also has a Linux driver you could try called ipw3945, although I would try that far after giving up on iwl3945 which I don't think you'll have to.
