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.

Select the check box to have both WPA2 and WPA wireless clients be able to 
communicate with the NBG6616 even when the NBG6616 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.
