Do you have knoppix up and running?? You say you have downloaded it but you haven't said you have burned the cd & are running Knoppix. If Knoppix is working properly and if the computer it is on actually has a functioning ethernet connection, it should autodetect & you should be 'on line' as soon as Knoppix is up. Try typing 'http://www.google.com' in the menu bar & see if it works.
