Clemens,

Glad to head that!

You wish just came true. To use plain iwconfig with wpa_supplicant,
here's what you need to do ...
just remember that the "order" is important ... you must set the
encryption key "before" you bring up the interface!!! This applies to
non-realtek devices as well.

# modprobe r8712u
# iwconfig wlan0 key restricted your-encrypted-password-same-as-wpa-psk-string
# ifconfig wlan0 up   <-- this comes after you set up the encryption above!
# iwconfig wlan0 mode ad-hoc essid your-ssid
# ifconfig wlan0 your-ip
# dhcpd wlan0

Larry, thanks again for your help getting me started on this. The
device is working great!

Jeff
