Thanks for replying. As I mentioned the WiFi on the same box runs fine
from Ubuntu or from Windows.
Here are the lspci and lsusb

Fedora Core 21, KDE spin, all patches up to date.
Have run for many months using WiFi almost exclusively. Started using OpenVPN a
couple of months ago with a commercial VPN provider. (Not sure if that
matters). That has worked fine.
Got notification from Apper that some packages needed updating, including
kernel. Performed the update from the Apper UI. I don't know if Networkmanager
was in the list.
After reboot, WiFi no longer works, in fact, the whole WiFi interface has
disappeared from ifconfig and from the NetworkServices UI. I plugged in an
ethernet cable, and it works fine. Machine is triple-boot, FC21, Win7 and
Ubuntu LTS 14.04. WiFi works fine in Win and Ubu.
I tried re-adding the interface, wlp8s0 using the Connection Editor. Seemed
happy, but it still won't start nor list in ifconfig
If the device isn't listed in ifconfig the the kernel cannot see it, and
thus NetworkManager can't see it. It seems like there is either a
hardware problem with your wifi device, or the kernel has been updated
and no longer recognizes the wifi device. What is the output of 'lsusb'
and 'lspci' when those commands are run in a terminal on your machine?

I found this in the messages log around the time of the failure, but googling
this does not produce any meaningful help:

Sep 12 23:16:04 KD1YV1 NetworkManager[733]: <info> (wlp8s0): deactivating

Help!
