DESCRIPTION
Choose WPA-PSK or WPA2-PSK from the drop-down list box.
This field is only available for WPA2-PSK. Select this if you want the
ZyXEL Device to support WPA-PSK and WPA2-PSK simultaneously.
Select the encryption type (TKIP, AES or TKIP+AES) for data
encryption.
Select TKIP if your wireless clients can all use TKIP.
Select AES if your wireless clients can all use AES.
Select TKIP+AES to allow the wireless clients to use either TKIP or
AES.
The encryption mechanisms used for WPA(2) and WPA(2)-PSK are
the same. The only difference between the two is that WPA(2)-PSK
uses a simple common password, instead of user-specific credentials.
Type a pre-shared key from 8 to 63 case-sensitive ASCII characters
(including spaces and symbols).
The Group Key Update Timer is the rate at which the AP (if using
WPA(2)-PSK key management) or RADIUS server (if using WPA(2)
key management) sends a new group key out to all clients. The re-
keying process is the WPA(2) equivalent of automatically changing the
WEP key for an AP and all stations in a WLAN on a periodic basis.
Setting of the Group Key Update Timer is also supported in WPA(2)-
PSK mode. The ZyXEL Device default is 1800 seconds (30 minutes).
