the following screen.

Figure 63 Security: WPA-PSK, WPA2-PSK or WPA2-PSK-MIX

The following table describes the labels not previously discussed

Table 32 Security: WPA-PSK, WPA2-PSK or WPA2-PSK-MIX

LABEL DESCRIPTION

Profile Name Type a name to identify this security profile.

Security Mode Choose WPA-PSK, WPA2-PSK or WPA2-PSK-MIX in this field.

Pre-Shared Key The encryption mechanisms used for WPA and WPA-PSK are the same. The only

difference between the two is that WPA-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

Specify how often wireless stations 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). Alternatively, enter “0” to turn reauthentication off.

Note: If wireless station authentication is done using a RADIUS

server, the reauthentication timer on the RADIUS server has

priority.

Idle Timeout The ZyXEL Device 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).

Group Key

Update Timer

The Group Key Update Timer is the rate at which the AP sends a new group key

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 ZyXEL Device’s default is 1800 seconds (30 minutes).
