7.2.4
WPA(2) Authentication
Use this screen to configure and enable WPA or WPA2 authentication. Click the
Wireless
LAN
link under
Network
to display the
AP
screen. Select
WPA
,
WPA2
or
WPAMixed
from
the
Security Mode
list.
Table 31
Network > Wireless LAN > AP: WPA(2)-PSK
LABEL
DESCRIPTION
Security Mode
Choose
WPA-PSK
or
WPA2-PSK
or
WPAPSKMixed
from the drop-down list
box.
Select
WPAPSK Mixed
if you want the ZyXEL Device to support WPA-PSK and
WPA2-PSK simultaneously.
Pre-Shared Key
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).
WPA Group Key
Update Timer
The
WPA 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
WPA Group Key Update Timer
is also
supported in
WPA(2)-PSK
mode. The ZyXEL Device default is
1800
seconds (30
minutes).

Security Mode
Choose
WPA
,
WPA2
or
WPAMixed
from the drop-down list box.
Select
WPAMixed
if you want the ZyXEL Device to support WPA and WPA2
simultaneously.
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).
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).

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.
Accounting Server (optional)
IP Address
Enter the IP address of the external accounting server in dotted decimal notation.
Port Number
Enter the port number of the external accounting server.
You need not change this value unless your network administrator instructs you
to do so with additional information.
Shared Secret
