Under Shared authentication, each wireless station is assumed to have received a secret
shared key over a secure channel that is independent from the 802.11 wireless network
communications channel.
Under WPA and WPA-PSK authentication, the use of 802.1x authentication is required.
For wireless networks without a Remote Authentication Dial-In User Service
(RADIUS) infrastructure, WPA supports the use of a preshared key. For wireless net-
works with a RADIUS infrastructure, Extensible Authentication Protocol (EAP) and
RADIUS is supported.

Enable 802.1x authentication: 802.1X is the IEEE standard that offers additional secu-
rity for local area networks. It provides authentication for user devices attached to an
Ethernet network, whether wired or wireless. A security protocol packet such as TLS or
MD5 encapsulated in an EAP is used in conjunction with the 802.1X standard to
authenticate users at the MAC layer. Available EAPs are listed in the dropdown menu
next to the EAP option.
To activate 802.1X, highlight 802.1x authentication, and check the checkbox.
