you proberbly need to give a litle bit more info on this one. IE is it a cable connection or a router connection you are using, who is your ISP etc.

Normally if you have a broadband connection using a router and your isp uses dymanmic ip addressing knoppix will pick this up out of the box, I dont even need to put in a password or user name it recognises my connection no problems.

your windows network config has no bearing on knoppix at all, it is completley independent. post some more info
