Ok first off i have a Toshiba Satellite L300D with an Atheros AR700EG.

My laptop is not on the "supported hardware" list but i have read on google that all Atheros are supported... (could someone please confirm me that my hardware is supported?)

So i successfully managed to download and get Backtrack3 working on an usb key. I can boot it,

After aunching the console and typing "airmon-ng start wlan0" , here's what i get :
wifi0 Atheros madwifi-ng
ath0 Atheros madwifi-ng VAP (parent: wifi0)
(there is around 10 wlan around my house, and i don't see any, including the one i want to test with the proprietary's authorisation...)

then if i type "airodump-ng -w out -c 10 --bssid 00:16:41:C9:E0:3F wlan0" here's what i get :
Interface wlan0:
ioctl(SIOCGIFINDEX) failed: No such device
Any help would be greatly appreciated!
