The WEP tab displays the WEP settings. Encryption is designed to make the data
transmission more secure. You may select 64 or 128-bit WEP (Wired Equivalent
Privacy) key to encrypt data (Default setting is Disable). WEP encrypts each frame
transmitted from the radio using one of the Keys from a panel. When you use WEP to
communicate with the other wireless clients, all the wireless devices in this network
must have the same encryption key or pass phrase. The following information is

The technology is designed to work with existing Wi-Fi products that have been
enabled with WEP. WPA provides improved data encryption through the Temporal
Key Integrity Protocol (TKIP), which scrambles the keys using a hashing algorithm and
by adding an integrity-checking feature which makes sure that keys haven’t been
tampered with. EAP (Extensible Authentication Protocol) is an extension to the PPP
