From PlcWiki
Wifi setup
To bring station to wifi follow these steps:
1) create or update /etc/sysconfig/network-scripts/ifcfg-wlan0
ONBOOT=yes
DEVICE=wlan0
TYPE=Wireless
ESSID=xxxx
RATE=auto
BOOTPROTO=static
IPADDR=x.x.x.x
NETMASK=x.x.x.x
BROADCAST=x.x.x.x
NETWORK=x.x.x.x
GATEWAY=x.x.x.x
USERCTL=no
NM_CONTROLLED=no
MODE=Managed
PEERDNS=yes
IPV6INIT=no
2) disable eth0, edit /etc/sysconfig/network-scripts/ifcfg-eth0
ONBOOT=no
3) edit /etc/wpa_supplicant/wpa_supplicant.conf, add output from command
"wpa_passphrase <ssid> <passphrase>
4) set service "wpa_supplicant" to be started on boot
chkconfig wpa_supplicant on
5) set system parameter in file /etc/sysconfig/wpa_supplicant
INTERFACES="-iwlan0"
6) reboot
It is good to have physical access to station to be able in case of problems make corrections ;). To use both interfaces one active and one as backup see Bonding.
