Appendix B: Configuring Security on Wireless Clients
234
Configuring WPA/WPA2 Enterprise (RADIUS) Security on a Client
Wi-Fi Protected Access 2 ( WPA2 ) with Remote Authentication Dial-In User
Service ( RADIUS ) is an implementation of the Wi-Fi Alliance IEEE 802.11
standard, which includes Advanced Encryption Standard ( AES ), Counter
mode/CBC-MAC Protocol ( CCMP ), and Temporal Key Integrity Protocol
( TKIP ) mechanisms. This mode requires the use of a RADIUS server to
authenticate users.
This security mode also provides backwards-compatibility for wireless
clients that support only the original
WPA .
When you configure WPA/WPA2 Enterprise (RADIUS) security mode on
the access point, you have a choice of whether to use the built-in
authentication server or an external RADIUS server that you provide.
The AT-WA7400 Wireless Access Point’s built-in authentication server
supports Protected Extensible Authentication Protocol (EAP) known as
EAP/PEAP and Microsoft Challenge Handshake Authentication Protocol
Version 2 (MSCHAP V2), which provides authentication for point-to-point
(PPP) connections between a Windows-based computer and network
devices such as access points.
If you configure the network (access point) to use security mode and
choose the built-in authentication server, you must configure client
stations to use WPA/WPA2 Enterprise (RADIUS) and EAP/PEAP.
If you configure the network (access point) to use this security mode with
an external RADIUS server, you must configure the client stations to use
WPA/WPA2 Enterprise (RADIUS) and whichever security protocol your
RADIUS server is configured to use.
WPA/WPA2
Enterprise
(RADIUS) Client
Using EAP/PEAP
The built-In authentication server on the AT-WA7400 Wireless Access
Point uses Protected Extensible Authentication Protocol (EAP) known as
EAP/PEAP.
ˆ If you are using the Built-in Authentication server with WPA/WPA2
Enterprise (RADIUS) security mode on the AT-WA7400 Wireless
Access Point, then you will need to set up wireless clients to use
PEAP.
ˆ Additionally, you may have an external RADIUS server that uses EAP/
PEAP. If so, you will need to (1) add the AT-WA7400 Wireless Access
Point to the list of RADIUS server clients, and (2) configure your WPA/
WPA2 Enterprise (RADIUS) wireless clients to use PEAP.
