WPA / WPA2: The Wi-Fi Alliance put together WPA / WPA2 as a data encryption
method for 802.11 wireless LANs. WPA is an industry-supported, pre-standard
version of 802.11i utilizing the Temporal Key Integrity Protocol (TKIP), which fixes
the problems of WEP, including using dynamic keys.
WPA / WPA2 Pre-Shared Key: Set the WPA / WPA2 Pre-Shared Key (PSK).
WPA / WPA2 Group Rekey Interval: Set the WPA / WPA2 Group Rekey Interval in
seconds. Leave blank or set to zero to disable periodic re-keying.
Radius Server: Set the IP address of the RADIUS server to use for authentication
and dynamic key derivation.
RADIUS Server: It is responsible for receiving user connection requests,
authenticating the user, and then returning all of the configuration information
necessary for the client to deliver the server to the user.
Radius Port: Sets the UDP port number of the RADIUS server. The port number is
usually 1812 or 1645 and depends on the server.
Radius Key: Set the shared secret for the RADIUS connection.
Data Encryption (WEP): Selecting Off disables WEP data encryption. Selecting
WEP enables WEP data encryption and requires that a valid network key be set and
selected unless 802.1X is enabled.
WEP: It stands for Wired Equivalent Privacy, is a protocol for wireless LANs or local
area networks. This WEP is defined in the 802.11 Standard. WEP is designed so
security levels are maintained at the same level as the wired LAN. WEP’s aim is to
provide security by encrypting data over radio waves. WEP protects data as it’s
transmitted from one end point to another. WEP is used at two lowest layers, the
data link and physical layer. WEP is designed to make up for the inherent security in
wireless transmission as compared to wired transmission.
Shared Key Authentication: Set whether shared key authentication is required to
associate. A valid network key must be set and selected if required.
