DESCRIPTION
Security Mode
Choose WPA-PSK or WPA2-PSK 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 WPA2 and WPA wireless clients be able to
communicate with the ZyXEL Device even when the ZyXEL Device is using
WPA2-PSK or WPA2.
Pre-Shared Key
The encryption mechanisms used for WPA/WPA2 and WPA-PSK/WPA2-PSK are
the same. The only difference between the two is that WPA-PSK/WPA2-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
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 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.
priority.
Idle Timeout (In
Seconds)
The ZyXEL Device automatically disconnects a wireless station from the wireless
network after a period of inactivity. The wireless station needs to send the
username and password again before it can use the wireless network again. Some
wireless clients may prompt users for a username and password; other clients may
use saved login credentials. In either case, there is usually a short delay while the
wireless client logs in to the wireless network again.
This value is usually smaller when the wireless network is keeping track of how
This value is usually smaller when the wireless network is keeping track of how
much time each wireless station is connected to the wireless network (for example,
using an authentication server). If the wireless network is not keeping track of this
information, you can usually set this value higher to reduce the number of delays
caused by logging in again.
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).
