As a minimum you need to state whether you are connecting via the LAN (ethernet) or wirelessly, can you state your intention please.
Also can you tell us if you are using DHCP or static addressing on your LAN.

If youre on the LAN its easy, if you're using wireless then this is much harder for a beginner as it involves setting up ndiswrapper.

I have a Linksys AG241 (not wireless) and knoppix works fine.
