I'm running Gentoo and try to get my WLAN NIC going. I've done this many times before without much trouble. Now I've run out of luck.
The NIC is an Intel PRO/Wireless 2200BG, and I've installed the drivers without complications (version 1.1.3). I can scan networks, set an IP address on the NIC etc. The ONLY thing that doesn't work so far is SETTING THE WEP KEY:
#iwconfig eth1 key s:xxxxxxxxxxxxxxxxxx
Error for wireless request "Set Encode" (8B2A) :
SET failed on device eth1 ; Operation not supported
Why the heck is this showing up? The ipw2200 driver has supported WEP since way back, and the IEEE802.11 wep crypto stuff compiled without errors.
