IEEE 802.1x authentication provides authenticated access to 802.11 wireless networks and to wired Ethernet networks. 802.1x minimizes wireless network security risks and uses standard security protocols, such as RADIUS. For more information about 802.1x and 802.11, see Related Topics.

To configure settings on the Authentication tab, you must be a member of the local Administrators group.

For wired and wireless network connections, the settings in the Authentication tab apply to the network to which you are currently connected. If you are currently connected to a wireless network, you can verify the name of the network by clicking the Wireless Networks tab. The name of the network will appear in Visible networks and Preferred networks, and it will be preceded by an icon with a circle around it.
