Hi Tom,
System -> administration -> Network
delete your wlan interface, and be sure that it also
deletes /etc/sysconfig/network-scripts/ifcfg-wlan0
Of course back up the entire dir: /etc/sysconfig first.
then click New (to create a new interface)  and take it
from there. During that process, you will see an option
for the type of network - select managed (i.e you will be using something like wpa2-psk ,ccmp ..etc)
and also be sure that the kernel module for your wifi device is loaded:
lsmod | grep ??????   the-kernel-recognized-name-of-your-wifi-card
if not,  then
sudo modprobe ??????  (I do not know your card's name).
Also, be sure you remove the option -u from /etc/sysconfig/wpa_supplicant
before you restart the network.
Once you finish,
be sure to do
sudo service network restart


Cheers,

JD
