Using the Web-Based Advanced User Interface
Wi-Fi Protected Access (WPA)
WPA is a new Wi-Fi standard that was designed to improve upon the
security features of WEP. To use WPA security, the drivers and software
of your wireless equipment must be upgraded to support WPA. These
updates will be found on the wireless vendor's website. There are three
types of WPA security: WPA-PSK (no server), WPA (with radius server),
and WPA2.
WPA-PSK (no server) uses what is known as a pre-shared key as the
network key. A network key is basically a password that is between eight
and 63 characters long. It can be a combination of letters, numbers, or
characters. Each client uses the same network key to access the network.
Typically, this is the mode that will be used in a home environment.
WPA (with radius server) is a system where a radius server distributes
the network key to the clients automatically. This is typically found in
a business environment.
WPA2 requires Advanced Encryption Standard (AES) for encryption
of data, which offers much greater security than WPA. WPA uses both
Temporal Key Integrity Protocol (TKIP) and (AES) for encryption.
