Anyone know where I should start troubleshooting my wireless setup (DWL-650) for this problem? I upgraded Knoppix (via apt-get) and after the upgrade, my wireless interface has turned from eth0 into wlan0. I guess that shouldn't be a problem, but iwconfig can't seem to set the encryption:

# iwconfig wlan0 key s:fafbfcfdfe
Error for wireless request "Set Encode" (8B2A)
Set failed on device wlan0 ; Operation not permitted.

Hmm. wlcardconfig set up the card (with encryption) just fine when it was eth0, but now that it is wlan0 things aren't working. Ideas? Thanks!
