Check the Mac address under XP and under Knoppix on the same machine.  Can you 
ping the modem from XP?  What is the connection type?  Straight ethernet with 
the modem as a bridge or are you using PPP?  It may be that your ethernet card 
has an assignable Mac that the XP could provide and you could duplicate under 
Knoppix.  Can you put a hub between the XP machine and the cable modem and 
sniff the triaffic with your laptop?

My nephew's WinXP box is wired straight to a 2com "sharkfin" cable modem, and its Ethernet card is set up to use DHCP for obtaining IP address and DNS address.  The weird thing is that if I boot to a Knoppix CD, I get no connection, and my Linux laptop, which works just fine with DHCP supplied locally in the house, also gets no connection.  Even if I set the IP address, gateway, mask, broadcast, etc. manually, I get nothing - I can't even ping the cable modem using the gateway address.  The only thing I can get is a link light on the sharkfin (but I can't make it blink).  What's up with this?
