WPA(2) Authentication
The WPA2 security mode is currently the most robust form of encryption for wireless networks. It
requires a RADIUS server to authenticate user credentials and is a full implementation the security
protocol. Use this security option for maximum protection of your network. However, it is the least
backwards compatible with older devices.
The WPA security mode is a security subset of WPA2. It requires the presence of a RADIUS server
on your network in order to validate user credentials. This encryption standard is slightly older than
WPA2 and therefore is more compatible with older devices.

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

This field is only available for WPA2. Select this if you want the Device to support WPA and
WPA2 simultaneously.
Encryption
Select the encryption type (
TKIP

WPA2 Pre-
Authentication
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
Specify how often wireless stations have to resend usernames and passwords in order to
stay connected.
If wireless station 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 RADIUS
server sends a new group
key out to all clients.

Status
This field indicates whether this SSID is active. A yellow bulb signifies that this SSID is active.
A gray bulb signifies that this SSID is not active.
SSID
An SSID profile is the set of parameters relating to one of the Device’s BSSs. The SSID
(Service Set IDentifier) identifies the Service Set with which a wireless device is associated.
This field displays the name of the wireless profile on the network. When a wireless client
scans for an AP to associate with, this is the name that is broadcast and seen in the wireless
client utility.
Security
This field indicates the security mode of the SSID profile.
Guest WLAN
This displays if the guest WLAN function has been enabled for this WLAN.
If
Home Guest
displays, clients can connect to each other directly.
If
External Guest
displays, clients are blocked from connecting to each other directly.
N/A
displays if guest WLAN is disabled.
