Comment 44 for bug 464199

My Intel PRO/Wireless 5100 AGN worked fine under ubuntu 10.0 (after some initial flakiness), but hasn't worked since I upgraded to 10.04 last night. My system is an HP dv7-2270us Intel Core-2 Quad. It has the Radio HW On/Off touch switch, but the wireless isn't recognized whether the switch is on (blue) or off (red).

The following is the output from sudo lshw -C Network. Any help would be much appreciated.
