upgraded knoppix (on hd) and wireless eth0 turned to wlan0

[tofergregg]

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!

Well, after a lot of searching, I figured out how to use wlanctl-ng, which is kind of ugly. I'm posting from my wireless card now, but I'm still curious about why the "easy setup" with eth0 has gone away and wlan0 replaced it. Here are the commands I typed to get it going:

# wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable

# wlanctl-ng wlan0 lnxreq_autojoin ssid=hot authtype=opensystem

# wlanctl-ng wlan0 dot11req_mibset mibattribute=dot11WEPDefaultKey0=fa:fb:fc:fd:fe

# ifconfig wlan0 up

# pump -i wlan0

This sets up my DWL-650 to connect to the ssid "hot" with the WEP key "fafbfcfdfe"
