Security Mode

Choose WPA2 or WPA2-MIXin this field.

 

 

ReAuthentication

Specify how often wireless stations have to resend usernames and passwords in

Timer

order to stay connected.

 

Enter a time interval between 10 and 9999 seconds. The default time interval is

 

1800 seconds (30 minutes). Alternatively, enter “0” to turn 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 ZyXEL Device automatically disconnects a wireless station from the wired

 

network after a period of inactivity. The wireless station needs to enter the

 

username and password again before access to the wired network is allowed.

 

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

 

 

Group Key

The Group Key Update Timer is the rate at which the AP sends a new group key

Update Timer

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 ZyXEL Device‘s default is 1800 seconds (30 minutes).

 

 

PMK Cache

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 caching, or Disable to switch this feature off.

 

 

Pre-

Pre-authentication allows a wireless client to perform authentication with a

Authentication

different AP from the one to which it is currently connected, before moving into the

 

new AP’s coverage area. This speeds up roaming. Select Enable to allow pre-

 

authentication, or Disable to switch it off.
