Comment 1 Arend van Spriel 2012-04-23 08:40:19 UTC 
What kernel version were you using before the update?
Comment 2 Ankur Sinha (FranciscoD) 2012-04-23 12:49:14 UTC 
As per https://bugzilla.redhat.com/show_bug.cgi?id=812506#c10 restarting NetworkManager got wireless working again:

systemctl restart NetworkManager.service

Not a kernel bug. Closing :)
