ECOMMENDATIONS
WPA/WPA2 Personal (PSK) is not recommended for use with the Professional Access Point when WPA/
WPA2 Enterprise (RADIUS) is an option.
USRobotics recommends that you use WPA/WPA2 Enterprise (RADIUS) mode instead, unless you have
interoperability issues that prevent you from using this mode.
For example, some devices on your network may not support WPA or WPA2 with
talking to a
server. Embedded printer servers or other small client devices with very limited space for
implementation may not support RADIUS. For such cases, USRobotics recommends that you use WPA/
WPA2 Personal (PSK).

When to Use WPA/WPA2 Enterprise (RADIUS)
Wi-Fi Protected Access 2 (
) with Remote Authentication Dial-In User Service (
) is an
implementation of the Wi-Fi Alliance IEEE
standard, which includes Advanced Encryption
Standard (
), Counter mode/CBC-MAC Protocol (
), and Temporal Key Integrity Protocol (
)
mechanisms. This mode requires the use of a RADIUS server to authenticate users. WPA/WPA2
Enterprise (RADIUS) provides the best security available for wireless networks.
This security mode also provides backward compatibility for wireless clients that support only the original

ECOMMENDATIONS
WPA/WPA2 Enterprise (RADIUS) mode is the recommended mode. The
(
) and
encryption algorithms used with WPA modes are far superior to the
algorithm used for Static
or
IEEE 802.1x modes. Therefore, CCMP (AES) or TKIP should be used whenever possible. All WPA modes
allow you to use these encryption schemes, so WPA security modes are recommended above the others
when using WPA is an option.
Additionally, this mode incorporates a RADIUS server for user authentication, which gives it an edge over
WPA/WPA2 Personal (PSK) mode.
Use the following guidelines for choosing options within the WPA/WPA2 Enterprise (RADIUS) mode

You have a choice of using the Pro-
fessional Access Point embedded
RADIUS server or an external
RADIUS server. The embedded
RADIUS server supports Protected
(PEAP) and MSCHAP V2.
