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

yum install rfkill

Then provide the output of "rfkill list"

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.
