EAP Authentication

EAP (Extensible Authentication Protocol) is an Enterprise authentication protocol that can be used in both a
wired and wireless network environment. EAP requires the use of an 802.1x Authentication Server, also
known as a Radius server. Although there are currently over 40 different EAP methods defined, the current
internal Modero 802.11g wireless card and accompanying firmware only support the following EAP methods
(listed from simplest to most complex):

The following use certificates:

EAP requires the use of an 802.1x authentication server (also known as a Radius server). Sophisticated Access
Points (such as Cisco) can use a built-in Radius server. The most common RADIUS servers used in wireless
networks today are:
