ParameterDescriptionAuthentication Mode This setting has to be consistent with the wireless network that the device intends to connect.
Open System – No authentication is needed among the wireless network.
Shared Key – Only wireless devices using a shared key (WEP Key identified) are allowed to connecting each other.
802.1x – You can also enable IEEE 802.1x setting to use the authentication server or certification server to authenticate client users.
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 – 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.
WPA2 – Like WPA, WPA2 supports IEEE 802.1x / EAP authentication or PSK technology. It also includes a new advanced encryption mechanism using the Advanced Encryption Standard (AES). AES is required to the corporate user or government users.
