Appendix B: Wireless Zero Config

Wireless Information

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-PSKauthentication, 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.

Network Key: This text box is used to specify a 5 or 13 ASCII character sequence or an equivalent 10 or 26 Hexadecimal digit sequence that matches the active WEP key on the access point.

To assign a Network key, highlight The key is provided automatically, and uncheck the checkbox to disable this option.

Key Index: This field is used to identify the WEP key. Enter a value from 1 to 4.

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.
