Figure 60 Wireless: WPA-PSK/WPA2-PSK

The following table describes the wireless LAN security labels in this screen.

Table 35 Wireless: WPA-PSK/WPA2-PSK

LABEL DESCRIPTION

Security Mode Choose WPA-PSK or WPA2-PSK from the drop-down list box.

WPA Compatible This check box is available only when you select WPA2-PSK or WPA2 in the

Security Mode field.

Select the check box to have both WPA2 and WPA wireless clients be able to

communicate with the ZyXEL Device even when the ZyXEL Device is using

WPA2-PSK or WPA2.

Pre-Shared Key The encryption mechanisms used for WPA/WPA2 and WPA-PSK/WPA2-PSK

are the same. The only difference between the two is that WPA-PSK/WPA2-PSK

uses 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

Timer (In

Seconds)

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

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 client authentication is done using a RADIUS server, the reauthentication timer on the RADIUS server has priority.
