When this happens (haven't seen it recently in F8 fully up2date), I
begin by restarting the NetworkManager service.  That's almost always
enough, but if not, I stop the service, rmmod the wireless driver,
modprobe the driver, then restart the service.  I've not had to resort
to rebooting in quite a while.

(Note that NM is a system service that runs at boot.  The applet runs at
login, but connects with the system service.  Logging out has no effect
on the service.)

That's way more plausible than the theory that they are spending their
time coding rather than documenting.  The latter just never happens with
open-source projects...
