The following table describes the labels in this screen.

Table 33 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 NBG-460N even when the NBG-460N is
	using WPA2-PSK or WPA2.
ReAuthentication	Specify how often wireless stations have to resend usernames and
Timer (in	passwords in order to stay connected. Enter a time interval between
seconds)	10 and 9999 seconds. The default time interval is 0 or no
	reauthentication.

	Note: If wireless station authentication is done using a RADIUS
	server, the reauthentication timer on the RADIUS server
	has priority.
Idle Timeout	The NBG-460N 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	The Group Key Update Timer is the rate at which the AP (if using
Update Timer	WPA-PSK/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 NBG-460N
	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 127 alphanumeric characters) as the key to
	be shared between the external authentication server and the NBG-
	460N.
	The key must be the same on the external authentication server and
	your NBG-460N. 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.
