Idle Timeout

(Seconds)

The ZyWALL 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.

Authentication

Databases

Click RADIUS to go to the RADIUS screen where you can configure the ZyWALL to

check an external RADIUS server.

WPA Group Key

Update Timer

(Seconds)

The WPA Group Key Update Timer is the rate at which the AP (if using WPA-PSK

key management) or RADIUS server (if using WPA key management) sends a new

group key out to all clients. The re-keying process is the WPA equivalent of

automatically changing the WEP key for an AP and all stations in a WLAN on a

periodic basis. Setting of the WPA Group Key Update Timer is also supported in

WPA-PSK mode.

Apply Click Apply to save your changes back to the ZyWALL.
