DESCRIPTION

Name

Type a name to identify this security profile.

 

 

Security Mode

Select WPA-PSK, WPA2-PSKor WPA2-PSK-MIXfrom the drop-down list.

 

 

Pre-Shared Key

The encryption mechanisms used for WPA(2) and WPA(2)-PSKare the same. The

 

only difference between the two is that WPA(2)-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 clients have to resend user names and passwords in

Timer

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

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 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)-PSKmode.
