The following table describes the wireless LAN security labels in this screen.
Table 33 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 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).
