Using EAP-TLS
After Profile Selection or Card Insertion
After you (or auto profile selection) select a profile that uses host-based EAP authentication and you
configure the card in Windows 2000 (with Service Pack 3 and the Windows 2000 Wireless 802.1X hot
fix) or XP for EAP-TLS authentication or you eject and reinsert the client adapter while this profile is
selected, follow the steps below to EAP authenticate.
Step 1
If your computer is running Windows XP and a pop-up message appears above the Windows system tray
informing you that you need to accept a certificate to begin the EAP authentication process, click the
message and follow the instructions provided to accept the certificate.
Note
You should not have to accept a certificate for future authentication attempts. After you
accept one, the same certificate is used subsequently.
Step 2
If a message appears indicating the root certification authority for the server’s certificate, and it is the
correct certification authority, click OK to accept the connection. Otherwise, click Cancel.
Step 3
If a message appears indicating the server to which your client adapter is connected, and it is the correct
server to connect to, click OK to accept the connection. Otherwise, click Cancel.
Step 4
The client adapter should now EAP authenticate. To verify authentication, double-click My Computer,
Control Panel, and Network Connections. Click View and Refresh to obtain the current status. The
status appears to the right of your Wireless Network Connection. If the client adapter is authenticated,
the status reads, “Authentication succeeded.”
After a Reboot or Logon
After your computer reboots or you log on using your Windows username and password, the EAP
authentication process begins automatically and the client adapter should EAP authenticate.
To verify authentication, double-click My Computer, Control Panel, and Network Connections. The
status is displayed to the right of your Wireless Network Connection. Click View and Refresh to obtain
the current status. If the client adapter is authenticated, the status reads, “Authentication succeeded.”
