2: Select TKIP when any WPA clients do not support AES. Select AES only if all clients support AES.
CLI Commands for WPA Using Pre-shared Key Security – Be sure to first disable
802.1X port authentication using the 802.1X command from the configuration mode.
Then, from the 802.11g interface configuration mode, use the vap command to
access each VAP interface to configure other security settings.
From the VAP interface configuration mode, use the authentication command to
set the access point to "Open System." Use the encryption command to enable
data encryption. To enable WPA to be required for all clients, use the wpa-clients
command. Set the broadcast and multicast key encryption using the
multicast-cipher command. Use the wpa-mode command to enable the
Pre-shared Key mode. To enter a key value, use the wpa-psk-type command to
specify a hexadecimal or alphanumeric key, and then use the wpa-pre-shared-key
command to define the key. To view the current security settings, use the show
interface wireless g 0 command (not shown in example).
