I've been struggling to apply the patches on trunk, without success. It seems things have changed substantially since those patches were written. However thanks to your advise (thanks to all), I've managed to get wifi up using macchanger, like this: iw phy0 interface add wlan0 type managed macchanger -m 22:ef:22:12:12:12 wlan0 ifconfig wlan0 up Up to now all I can say is that it is able to scan networks with iwlist sc. My question is: while we wait for the new patches, would it be possible to use macchanger (or something like that) at some specific line/s in the configuration scripts of the device in order to trick it into thinking that it has a valid MAC?
