Interesting. You may want to make sure that it is actually doing
encryption. If it is doing encryption I am very curious how you have
gotten it to work.
Today I loaded openwrt-x86 on a spare laptop I had. It has a Compex
WLM54G Atheros card in it.
I got it all set up and working without encryption. Then in the luci gui
I set encryption to WPA-PSK. Rebooted, and looking at the process list
there is no wpa_supplicant or hostapd. Also there is no encryption key
when I ran iwconfig. It connects to an open adhoc node. Digging further,
it looks like /lib/wifi/madwifi.sh will only set up encryption for ap,
wpa, and sta modes. Also, /lib/wifi/wpa_supplicant.sh seems to not have
the necessary key-mgmt=WPA-NONE needed for adhoc. Below is my output.
