Using wpa_supplicant.  If it is not installed, yum install 
wpa_supplicant and you will need to edit /etc/sysconfig/wpa_supplicant 
and /etc/wpa_supplicant/wpa_supplicant.conf.  Examples are in 
/usr/share/doc/wpa_supplicant-* or plenty of them online .. You probably 
also need to rename/mv the SXXwpa_supplicant in your /etc/rcX.d to start 
wpa_supplicant before network.
