DESCRIPTION

Security Mode

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

WPA Compatible

This check box is available only when you select WPA2-PSK or WPA2
in the Security Mode field.

Select the check box to have both WPA-PSK and WPA wireless clients
be able to communicate with the ZyXEL Device even when the ZyXEL
Device is using WPA2-PSK or WPA2.

ReAuthentication
Timer

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.

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.

WPA 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 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.
