Chapter 4 Wireless LAN

The following table describes the labels in this screen.

Table 14 Network > Wireless LAN > General: WPA/WPA2

LABEL	DESCRIPTION
WPA Compatible	This check box is available only when you select WPA2-PSKor 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	Specify how often wireless stations have to resend usernames and passwords in
Timer (in seconds)	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	The Group Key Update Timer is the rate at which the AP (if using WPA-PSK/
Timer	WPA2-PSKkey management) or RADIUS server (if using WPA/WPA2 key
	management) sends a new group key out to all clients. The re-keying process is
	the WPA/WPA2 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-PSKmode. The ZyXEL Device
	default is 1800 seconds (30 minutes).
Authentication Server
IP Address	Enter the IP address of the external authentication server in dotted decimal
	notation.
Port Number	Enter the port number of the external authentication server. The default port
	number is 1812.
	You need not change this value unless your network administrator instructs you
	to do so with additional information.
Shared Secret	Enter a password (up to 31 alphanumeric characters) as the key to be shared
	between the external authentication server and the ZyXEL Device.
	The key must be the same on the external authentication server and your ZyXEL
	Device. The key is not sent over the network.
Accounting Server
Active	Select Yes from the drop down list box to enable user accounting through an
	external authentication server.
IP Address	Enter the IP address of the external accounting server in dotted decimal notation.
Port Number	Enter the port number of the external accounting server. The default port number
	is 1813.
	You need not change this value unless your network administrator instructs you
	to do so with additional information.
Shared Secret	Enter a password (up to 31 alphanumeric characters) as the key to be shared
	between the external accounting server and the ZyXEL Device.
	The key must be the same on the external accounting server and your ZyXEL
	Device. The key is not sent over the network.
Apply	Click Apply to save your changes back to the ZyXEL Device.
Reset	Click Reset to reload the previous configuration for this screen.
