Figure 114 Wireless: WPA(2)-PSK

The following table describes the wireless LAN security labels in this screen.

Table 38 Wireless: WPA(2)-PSK

LABEL DESCRIPTION

Security Mode Choose WPA-PSK or WPA2-PSK from the drop-down list box.

WPA Compatible This field is only available for WPA2-PSK. Select this if you want the ZyXEL

Device to support WPA-PSK and WPA2-PSK simultaneously.

Pre-Shared Key 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).

ReAuthentication

Timer (in

seconds)

Specify how often wireless stations have to resend usernames and passwords in

order to stay connected. Enter a time interval between 10 and 9999 seconds. The

default time interval is 1800 seconds (30 minutes).

Note: If wireless station authentication is done using a RADIUS

server, the reauthentication timer on the RADIUS server has

priority.

Idle Timeout The ZyXEL Device automatically disconnects a wireless station from the wired

network after a period of inactivity. The wireless station needs to enter the

username and password again before access to the wired network is allowed. The

default time interval is 3600 seconds (or 1 hour).

Group Key

Update Timer

The Group Key Update Timer is the rate at which the AP (if using WPA(2)-PSK

key management) or RADIUS server (if using WPAWPA(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).
