the set up depends on your Isp, and what sought of modem you are using. some use ppoe some ppoa and also if you are using a USB modem from your isp for connection forget it, its more trouble than its worth trying to get it up and running.

My advice would be to get yourself a router and connect it to your lan card, and away you go. it will take you about two minutes to get going and virtually every linux distro inc knoppix will recognise it at start up, no props.

Hope this helps
