HP Networking :: Pavilion G7 / Wireless Hardware Cannot Be Detected

I've seem to lost all ability to connect to or even find a wireless signal.
 
Normally after I log on the wireless indicator light on the F12 key goes from orange (off) to white (on) but for some reason its staying orange. At this time I get a message saying “wireless hardware cannot be detected”.
 
If I hit the F12 button to turn on the wireless signal I get a HP box that says – wireless is turned off “The wireless devices on your computer are turned off. To turn on the wireless devices, press the wireless button”. I do this and the message goes away but the wireless indicator light is still orange and I’m getting no signal.
 
It doesn’t appear that my wireless router is the problem as I can’t detect any signal from my neighbors or when I take my laptop to work, as I did before this issue popped up. I’ve ran my HP Support Assistant and Troubleshoot – Network and Internet Connectivity – HP network Check, but it doesn’t find any type of wireless device. The wired connection still works.
 
My machine is running Windows7 Home Premium.
