LABEL
DESCRIPTION
Security Mode
Choose WPA or WPA2 from the drop-down list box.
Active
Compatible
This field is only available for WPA2. Select this if you want the ZyXEL
Device to support WPA and WPA2 simultaneously.
Encryption
Select the encryption type (TKIP, AES or TKIP+AES) for data
encryption.
WPA2
Preauthenticatio
n
This field is available only when you select WPA2.
Pre-authentication enables fast roaming by allowing the wireless client
(already connecting to an AP) to perform IEEE 802.1x authentication
with another AP before connecting to it. Select Enabled to turn on
preauthentication in WAP2. Otherwise, select Disabled.
Network Re-auth
Interval
This field is available only when you select WPA2.
Specify how often wireless clients have to resend usernames and
passwords in order to stay connected. Enter a time interval between
10 and 2147483647 seconds.
Note: If wireless client authentication is done using a RADIUS
server, the reauthentication timer on the RADIUS server has
priority.
Group Key
Update Timer
The Group Key Update Timer is the rate at which the AP (if using
WPA(2)-PSK key management) or RADIUS server (if using WPA(2)
key management) sends a new group key out to all clients. The re-
keying process is the WPA(2) 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. The ZyXEL Device default is 1800 seconds (30
minutes).
Authentication Server
IP Address
Enter the IP address of the external authentication server in dotted
decimal notation.
Port Number
Enter the port number of the external authentication server. The
default port number is 1812.
You need not change this value unless your network administrator
instructs you to do so with additional information.
Shared Secret Enter a password (up to 31 alphanumeric characters) as the key to be
shared between the external authentication server and the ZyXEL
Device.
The key must be the same on the external authentication server and
your ZyXEL Device. The key is not sent over the network.
