I'm booting my machine with a Knoppix V5.0.1 live CD. It will not connect to the internet. I've got an Intel PRO/100VE network card, a Belkin router (4-port cable/DSL gateway), and a Motorola Surfboard SB5100 modem. When I try to connect the browser to the internet (or to my router at I get a "Connection is broken."

Any suggestions on setup or trouble-shooting?
