CHAPTER 4: SYSTEM CONFIGURATION
WIRED EQUIVALENT PRIVACY (WEP)
WEP provides a basic level of security, preventing unauthorized access to the
network, and encrypting data transmitted between wireless clients and the access
point. WEP uses static shared keys (fixed-length hexadecimal or alphanumeric
strings) that are manually distributed to all clients that want to use the network.
WEP is the security protocol initially specified in the IEEE 802.11 standard for
wireless communications. Unfortunately, WEP has been found to be seriously
flawed and cannot be recommended for a high level of network security. For
more robust wireless security, the access point provides Wi-Fi Protected Access
(WPA) for improved data encryption and user authentication.
Setting up shared keys enables the basic IEEE 802.11 Wired Equivalent Privacy
(WEP) on the access point to prevent unauthorized access to the network.
If you choose to use WEP shared keys instead of an open system, be sure to
define at least one static WEP key for user authentication and data encryption.
Also, be sure that the WEP shared keys are the same for each client in the wireless
network.

NOTE: If you choose to configure RADIUS MAC authentication together with
802.1X, the RADIUS MAC address authentication occurs prior to 802.1X
authentication. Only when RADIUS MAC authentication succeeds is 802.1X
authentication performed. When RADIUS MAC authentication fails, 802.1X
authentication is not performed.
