10.9.4 WLAN Add/Edit Screen: WPA/WPA2 Security

With WPA or WPA2 security, each user can have a separate user name and password. The
ZyWALL uses an external RADIUS server or the ZyWALL's internal user account list to
authenticate the user names and passwords. To configure and enable WPA or WPA2 security,
click Network > Interface > WLAN > Add (or Edit) to open the WLAN Edit screen. Select
WPA-Enterprise or WPA2-Enterprise as the Security Type. The following figure shows
the security fields.

DESCRIPTION
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).
Specify how often wireless stations have to resend usernames and passwords in
order to stay connected.
The default time interval is 1800 seconds (30 minutes). Alternatively, enter "0" to
turn reauthentication off.
Note: If a RADIUS server authenticates wireless stations, the
reauthentication timer on the RADIUS server has priority.
The ZyWALL 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 3000 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 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
ZyWALL's default is 1800 seconds (30 minutes).
