9.4.3 WPA/WPA2
In order to configure and enable WPA/WPA2; click the Wireless LAN link under Network to
display the General screen. Select WPA or WPA2 from the Security Mode list.
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
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).
