I'm running Ubuntu 12.04 with GNOME on a Dell Inspiron 1470, my wlan card is a Broadcom BCM4312. Was previously using Windows 7.

Now at startup both BT and Wifi are switched on. If I switch off bluetooth, wifi automatically does so. When I try the Fn command, f2 in this case, both adaptors switch either on or off.

Is there a way to get them to work independently once again?
