Hey mate have you had any luck on getting the wireless interface to work on Ubuntu on BRUME?? Im having the same issues and its really frustrating as this comment is the only one Ive managed to find.

Not sure if its an interface -up -down problem or a driver issue. Ive even plugged an external USB WiFi adapter in to get around the problem.

But cant see why this is needed because the BRUME I have is the wireless one !!!
