DESCRIPTION

 

 

Pre-Shared Key

The encryption mechanisms used for WPA and WPA-PSKare the same. The only

 

difference between the two is that WPA-PSKuses a simple common password,

 

instead of user-specific credentials.

 

Type a pre-shared key from 8 to 63 case-sensitive ASCII characters (including

 

spaces and symbols).

ReAuthentication

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

Timer (in seconds)

order to stay connected. Enter a time interval between 10 and 9999 seconds. The

 

default time interval is 1800 seconds (30 minutes).

 

Note: If wireless station authentication is done using a RADIUS

 

server, the reauthentication timer on the RADIUS server has

 

priority.

 

 

Idle Timeout

The ZyAIR 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).

WPA Group Key

The WPA Group Key Update Timer is the rate at which the AP (if using WPA-

Update Timer

PSK key management) or RADIUS server (if using WPA key management) 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 WPA Group Key Update Timer is also supported in

 

WPA-PSKmode. The ZyAIR default is 1800 seconds (30 minutes).
