Combination		Authenticationb	Server
802.1x WPA-WPA2	Authentication: WPA-WPA2-mixed	Local or Disabled	Yes
Mixed Mode	Encryption: Enable
	WPA Configuration: Required
	Cipher Suite: TKIP

	Set 802.1x key refresh and re authentication rates
WPA-WPA2 Mixed	Authentication: WPA-WPA2-PSK-mixed	Local or Disabled	No
Mode Pre-Shared Key	Encryption: Enable
	WPA Configuration: Required
	Cipher Suite: TKIP
	802.1x: Disable
	WPA Pre-shared Key Type: Hexadecimal or
	Alphanumeric
	Enter a WPA Pre-shared key

aThe configuration summary does not include the set up for MAC authentication (see page 5-10) or RADIUS server (see page 5-8).

bThe configuration of RADIUS MAC authentication together with 802.1x WPA or WPA Pre-shared Key is not supported.

cRADIUS server required only when RADIUS MAC authentication is configured.

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.

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.
