This setting has to be consistent with the wireless
networks that the adapter intends to connect.
Open System – No authentication is needed among
the wireless network.
Shared Key – Only wireless stations using a shared
key (WEP Key identified) are allowed to connecting
each other.
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 stations 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. The difference between WPA-PSK and
WPA2-PSK is that WPA2-PSK provides data
encryption via the AES. In contrast, WPA-PSK uses
Temporal Key Integrity Protocol (TKIP).
WPA 802.1X – WPA provides a scheme of mutual
authentication using either IEEE 802.1x/Extensible
Authentication Protocol (EAP) authentication or
pre-shared key (PSK) technology. It provides a high
level of assurance to enterprises, small businesses
and home users that data will remain protected and
that only authorized users may access their networks.
For enterprises that have already deployed IEEE
802.1x authentication, WPA offers the advantage of
leveraging existing authentication databases and
infrastructure.
