WPA-PSK/WPA2-PSK, or WPA /WPA2.
z Open
Open system authentication simply consists of two communications. The first is an
authentication request by the client that contains the station ID (typically the MAC
address). This is followed by an authentication response from the AP/router containing
a success or failure message. An example of when a failure may occur is if the client's
MAC address is explicitly excluded in the AP/router configuration.
z Shared
Shared key authentication relies on the fact that both stations taking part in the
authentication process have the same "shared" key or passphrase. The shared key is
manually set on both the client station and the AP/router. Three types of shared key
authentication are available today for home or small office WLAN environments.
z Auto
The AP will Select the Open or Shared by the client’s request automatically.
