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 resend usernames and passwords in

Timer

order to stay connected.

 

The default time interval is 1800 seconds (30 minutes). Alternatively, enter “0” to

 

turn reauthentication off.

 

Note: If a RADIUS server authenticates wireless stations, the

 

reauthentication timer on the RADIUS server has priority.

 

 

Idle Timeout

The ZyWALL 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 3000 seconds.

 

 

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

 

ZyWALL’s default is 1800 seconds (30 minutes).

10.9.4 WLAN Add/Edit Screen: WPA/WPA2 Security

With WPA or WPA2 security, each user can have a separate user name and password. The ZyWALL uses an external RADIUS server or the ZyWALL’s internal user account list to authenticate the user names and passwords. To configure and enable WPA or WPA2 security, click Network > Interface > WLAN > Add (or Edit) to open the WLAN Edit screen. Select WPA-Enterpriseor WPA2-Enterpriseas the Security Type. The following figure shows the security fields.
