DESCRIPTION
Select WPA or WPA2 to enable data encryption.
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 NBG5715 even when the NBG5715 is using WPA2-PSK
or WPA2.
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/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-PSK mode.
This field is available only when you select WPA2.
Specify how often wireless clients have to resend usernames and passwords in
order to stay connected. Enter a time interval between 10 and 999999
minutes.
Note: If wireless client authentication is done using a RADIUS server, the
reauthentication timer on the RADIUS server has priority.
This field is available only when you select WPA2.
Pre-authentication enables fast roaming by allowing the wireless client (already
connecting to an AP) to perform IEEE 802.1x authentication with another AP
before connecting to it. Select Enable to turn on preauthentication in WAP2.
Otherwise, select Disable.
Enter the IP address of the external authentication server in dotted decimal
notation.
Enter the port number of the external authentication server.
You need not change this value unless your network administrator instructs you
to do so with additional information.
