ReAuthentication 
Timer 

Specify how often wireless stations have to resend user names and 
passwords in order to stay connected. 

The default value is 0, which means the reauthentication off. 

Note: If wireless station authentication is done using a RADIUS 

server, the reauthentication timer on the RADIUS server 
has priority. 

Idle Timeout

The NWA automatically disconnects a wireless station from the wired 
network after a period of inactivity. The wireless station needs to 
enter the user name and password again before access to the wired 
network is allowed. 

The default time interval is 3600 seconds (or 1 hour).

Group Key Update 
Timer

The Group Key Update Timer is the rate at which the AP sends a 
new group key out to all clients. The re-keying process is the WPA 
equivalent of automatically changing the group 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 mode. The NWA default 
is 1800 seconds (30 minutes).
