Chapter 4 Using Advanced Setup
Security
There are four wireless security options: Off, WEP, WEP+802.1x, and WPA. The lat- ter three options are different types of wireless security.
Off
Selecting Off disables wireless security. Selecting this option allows any computer with wireless capability and the correct ESSID value to join the wireless network.
WEP
Selecting the security option “WEP” and clicking Next in the Wireless Settings screen generates the “WEP Key” screen. Here, the authentication type, encryp- tion level, and WEP keys are entered to activate WEP (Wired Equivalent Privacy) security encryption for the wireless network.
Authentication Type - There are three authentication types: Open, Shared, and Both. Open authentication allows any wireless-enabled device to recognize the Router, if the correct WEP key is enabled on the device. Shared allows only wire- less-enabled devices with the correct WEP key and Shared key to recognize the Router. Selecting Both enables both Open and Shared authentication types.
64-bit WEP - 64-bit WEP requires four separate keys. Each key comprises five hexa- decimal digit pairs. A hexadecimal digit consists of an alphanumeric character ranging from 0-9or A-F. An example of a 64-bit WEP key is: 4E-A3-3D-68-72. To create a set of 64-bit WEP keys, activate all four keys by clicking in the appropri- ate circles, then enter five hexadecimal digit pairs in each Key text box (Key 1-, Key 2-, Key 3-, Key 4-). After activating 64-bit WEP on the Router, a computer with wireless capability can join the network only if these same keys are entered in the computer’s wireless encryption scheme.
