WPA2
Preauthentication
This field is available only with WPA2 network authentication.
Turn on pre-authentication to enable fast roaming by allowing the
wireless client (already connected to an AP) to perform IEEE 802.1x
authentication with another AP before connecting to it.
Network Re-auth
Interval
This field is available only with WPA2 network authentication.
Specify how often wireless stations have to resend usernames and
passwords in order to stay connected. Enter a time interval between 0
and 4294967295 seconds. 0 disables the re-authentication.
Note: The re-authentication timer on the RADIUS server has
priority over your setting here.
WPA Group
Rekey Interval
This field is available only with WPA or WPA2 network authentication.
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. 0 disables the re-keying.
RADIUS Server
IP Address
The RADIUS fields are required with 802.1X and WPA/WPA2 network
authentication.
Enter the IP address of the external authentication server in dotted
decimal notation.
RADIUS Port 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.
RADIUS Key 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.
WPA Encryption Select the encryption type (TKIP, AES, or both) for data encryption.
Select TKIP if your wireless clients can all use TKIP.
Select AES if your wireless clients can all use AES.
Select TKIP + AES to allow the wireless clients to use either TKIP or
AES.
WEP Encryption WEP encryption is optional with Open network authentication. It is
required with Shared or 802.1X network authentication.
WEP (Wired Equivalent Privacy) provides data encryption to prevent
unauthorized wireless stations from accessing data transmitted over
the wireless network.
Encryption
Strength
If you are using WEP encryption, select 64-bit or 128-bit to set the
length of the encryption key.
