WPA/WPA2 Personal (PSK)
Wi-Fi Protected Access 2 ( WPA2 ) with Pre-Shared Key ( PSK ) is a Wi-Fi Alliance IEEE 802.11i standard,
which includes Advanced Encryption Algorithm ( AES ), Counter mode/CBC-MAC Protocol ( CCMP ), and
Temporal Key Integrity Protocol ( TKIP ) mechanisms. The Personal version of WPA2 employs a pre-
shared key (instead of using IEEE 802.1x and EAP as is used in the Enterprise WPA2 security mode). The
PSK is used for an initial check of credentials only.
This security mode is backward-compatible for wireless clients that support the original WPA .
If you select WPA/WPA2 Personal (PSK) Security Mode, you must provide the following:
Field Description
Authentication Server Select one of the following:
• Built-in —To use the authentication server provided with the Professional Access
Point. If you choose this option, you do not have to provide the Radius IP and
Radius Key; they are automatically provided.
• External —To use an external authentication server. If you choose this option you
must supply the Radius IP and Radius Key of the server you want to use.
Note: The RADIUS server is identified by its IP address and UDP port numbers for
the different services it provides.The RADIUS server User Datagram Protocol
(UDP) ports used by the access point are not configurable on the Professional
Access Point. (The access point is hard-coded to use RADIUS server UDP port
1812 for authentication and port 1813 for accounting.)
Radius IP Enter the Radius IP in the text box.
The Radius IP is the IP address of the RADIUS server.
The Professional Access Point internal authentication server is 127.0.0.1
For information on setting up user accounts, see “User Management” on page 53.
Radius Key Enter the Radius Key in the text box.
The Radius Key is the shared secret key for the RADIUS server. The text you enter
will be displayed as "*" characters to prevent others from seeing the RADIUS key
as you type.
(The Professional Access Point internal authentication server key is secret .)
This value is never sent over the network.
Enable RADIUS Accounting Click Enable RADIUS Accounting if you want to track and measure the resources that a
particular user has consumed. Resources measured include system time, amount
of data transmitted and received, and so on.
