LABEL DESCRIPTION
Security Mode Select WPA or WPA2 to enable data encryption.
WPA Compatible This check box is available only when you select WPA2-PSK or WPA2 in the Security
Mode field.

communicate with the NBG5615 even when the NBG5615 is using WPA2-PSK or WPA2.
Group Key Update
Timer
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.
PMK Cache Period 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.
