Knoppix does the very best it can to automatically figure out what hardware the PC has & it does this without human intervention. In your case it looks like it is finding the wired & wireless ethernet devices & is failing to initialize the wireless. You will need to tell knoppix to boot with certain settings called Cheat Codes http://www.knoppix.net/wiki/Cheat_Codes that will tell knoppix to not initialize the DHCP for all network devices.
knoppix nodhcp

Then when knoppix is up & running, you can either run the command netcardconfig or use the menu item in the Knoppix menu.

I hope this helps.
