The router is a linksys wireless-g, however it's not used wirelessly. I have no internet/router problems to speak of when running XP so I'm fairly certain the problem is on the Knoppix end. MAC adresses don't appear to be restricted in anyway, however if you're familiar with the router you could tell me how to find out for sure. DHCP server is enabled. Will get back to you momentarily on netcardconfig and ifconfig
