Name

Type a name to identify this security profile.

Security Mode

Select WPA, WPA2 or WPA2-MIX from the drop-down list.

ReAuthentication 

Timer 

Specify how often wireless clients have to resend user names and passwords in 

order to stay connected. Enter a time interval between 600 and 65535 seconds. 
If wireless client authentication is done using a RADIUS server, the 

reauthentication timer on the RADIUS server has priority. 

Idle Timeout 

The ZyWALL automatically disconnects a wireless client from the wireless network 

after a period of inactivity. The wireless client needs to send the username and 

password again before it can use the wireless network again. Some wireless 

clients may prompt users for a username and password; other clients may use 

saved login credentials. In either case, there is usually a short delay while the 

wireless client logs in to the wireless network again. 
This value is usually smaller when the wireless network is keeping track of how 

much time each wireless client is connected to the wireless network (for example, 

using an authentication server). If the wireless network is not keeping track of this 

information, you can usually set this value higher to reduce the number of delays 

caused by logging in again.
Enter a time interval between 600 and 65535 seconds.

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 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(2)-PSK mode.

PMK Cache

This field is available only when you select WPA2 or WPA2-MIX.
When a wireless client moves from one AP’s coverage area to another, it performs 

an authentication procedure (exchanging security information) with the new AP. 

Instead of re-authenticating a client each time it returns to the AP’s coverage area, 

which can cause delays to time-sensitive applications, the AP and the client can 

store (or “cache”) and use information about their previous authentication. 
Select Enable to allow PMK (Pairwise Master Key) caching, or Disable to switch 

this feature off.
