Hi,
On my netbook I booted a test kernel 3.8.0-rc4+ I compiled. Now after booting back into my regular Fedora kernel 3.6.11-5.fc17.i686.PAE my wifi network device remains permanently disappeared. No wifi networks displayed in Network Manager gui. Also the Network Manager syslog messages make it look like the device has completely disappeared.
Suggestions for restoring wifi welcome.
Thanks Mike

No (wlan0) related NetworkManager syslog messages afterwards at all.

Ignore the test kernel as a possible cause until you've checked everything else. Just because it happened after trying it and going back to a regular kernel doesn't mean it's responsible.

I once tracked a similar issue down to someone picking up a laptop in such a way that they hit the hardware disable switch on the front of a laptop, which was a toggle and went into permanent OFF state. Saw that with the bluetooth switch togglrf ON as well, tracking down why smart phone battery life went down when working from home. The laptop was trying to mate with the phone.
