I dont now think that this would be the right approach.
As far as I know networkmanager is one of the few that support these connection types, hardware is often not such a problem , you would be suprised what is supported by the kernel.
So basically youll need to remove or disable WICD which I believe is the default connection manager as used by bt.
Wow my apt get skills are rusty lol, gotta love pacman.
something like; apt-get remove wicd
Or just use; service wicd stop
Than youll have to install networkmanager.
Make sure that wicd is disabled or not installed.
Start the network manager daemon and nm-apllet.
Take a look there and see if you get anywhere with it.
(We are not talking Ethernet or Wireless right ??)
