3.10.1.1 Auth. Vs. Security
This option enables you to configure the authentication mode and encryption algorithm used within the
AP.
Parameter Description
Authentication Type There are four types of authentication mode supported.
Open – No authentication is needed among the wireless network.
WPA-PSK - It is a special mode designed for home and small
business users who do not have access to network authentication
servers. In this mode, known as Pre-Shared Key, the user
manually enters the starting password in their access point or
gateway, as well as in each wireless station in the network.
WPA-PSK takes over automatically from that point, keeping
unauthorized users that don't have the matching password from
joining the network, while encrypting the data traveling between
authorized devices.
WPA2-PSK - WPA2-PSK is also for home and small business.
WPA-PSK/WPA2-PSK – When selecting this mode, the AP
supports both WPA-PSK and WPA2-PSK.
