the SpeedTouch™
E-DOC-CTC-20041126-0014 v3.0
When a wireless client requests access to a network, it is required to be
authenticated by a central authentication server (RADIUS Server). Only an
authenticated user can access the wireless network.
Remote Authentication Dial-in User Service (RADIUS) is a protocol for carrying
authentication, authorization, and configuration information between a Network
Access Server which desires to authenticate its links and a shared Authentication
Server.
Following components are needed to establish an 802.1x environment in your
network.:
Windows 2000 Server: RADIUS server is installed using "Internet
Authentication Service" and Certificate Services is installed
AP (Router): It should be connected to Windows 2000 Advanced Server
through the LAN port. The DHCP server for the router is used and 802.1x must
be enabled.
802.1x client: A WLAN card supporting WEP.
