# This script will load and unload the wifi driver to put the wifi in

# ok(GUI loaded the driver) or loading(GUI is loading the driver) then
# the script won't do anything. Otherwise (GUI is not going to Turn On
# the Wifi) the script will load/unload the driver
# This script will get called after post bootup.
