Try this:

KNOPPIX (not START, but the Penguin) >> NETWORK / INTERNET >> KWIFIMANAGER

Then:

KNOPPIX >> NETWORK / INTERNET >> NETWORK CARD CONFIGURATION

If KWiFiManager doesnt recognize your card, you might need to use NDISWRAPPER to install the Windows driver that came with your WiFi card. Then...

KNOPPIX >> NETWORK / INTERNET >> NDISWRAPPER CONFIGURATON

After that, try the first and second steps again.
