DESCRIPTION

 

 

Security

Select WPA-PSKfrom the drop-down list.

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 resend user names and passwords in

Timer (Seconds)

order to stay connected. Enter a time interval between 10 and 65535 seconds.

 

If wireless station authentication is done using a RADIUS server, the

 

reauthentication timer on the RADIUS server has priority.

Idle Timeout

The ZyWALL automatically disconnects a wireless station from the wired network

(Seconds)

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.

WPA Group Key

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

Update Timer

key management) or RADIUS server (if using WPA key management) sends a new

(Seconds)

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-PSK mode.
