DESCRIPTION
Type a name to identify this security profile.
Select WPA-PSK, WPA2-PSK or WPA2-PSK-MIX from the drop-down list.
The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The
only difference between the two is that WPA(2)-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).
Specify how often wireless clients have to resend user names and passwords in
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.
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.
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 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)-PSK mode.
