the following screen.
Figure 59 Security: WPA-PSK, WPA2-PSK or WPA2-PSK-MIX
The following table describes the labels not previously discussed
Table 31 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).
