http://askubuntu.com – Today I acquired a Dell XPS 1645. Ubuntu seems to run alright on it however The bluetooth is not detected and the WiFi doesn't work. The WiFi is especially weird because I actually have the restricted driver enabled for it. It also worked for a short while when I first booted into Ubuntu however now there isn't even an option to enable wireless. Both 'etho' and 'lo' return 'no wireless extentions' when running iwconfig and 'sudo ip link set wlan0' returns 'cannot find device "wlan0". It uses the Broadcom BCM4312 802.11b/g LP-PHY which seems to be contained in plenty of certified Ubuntu sys (HowTos)
