Table 40 Wireless: WPA/WPA2
LABEL DESCRIPTION
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 WPA2 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 (In Seconds)
Specify how often wireless clients 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 client authentication is done using a RADIUS
server, the reauthentication timer on the RADIUS server has
priority.
Idle Timeout (In
Seconds)
The ZyXEL Device automatically disconnects a wireless client from the wired
network after a period of inactivity. The wireless client 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 (In Seconds)
The Group Key Update Timer is the rate at which the AP (if using WPA-PSK/
WPA2-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-PSK/WPA2-PSK mode. The default is 1800 seconds
(30 minutes).
