Step 5 Select the Use a certificate on this computer option.
Step 6 Select the Validate server certificate checkbox.
Step 7 Make sure that the name of the certificate authority from which the EAP-TLS certificate was
downloaded appears in the Trusted root certificate authority field.
Step 8 Click OK to save your settings. The configuration is complete.
Step 9 If a pop-up message appears above the 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. The same
certificate, which is tied to your login, will be used.
The client adapter should now EAP authenticate.
Note Whenever the computer reboots and you enter your Windows username and password, the
EAP authentication process begins automatically and the client adapter should EAP
authenticate.
Step 10 To verify authentication, double-click My Computer, Control Panel, and Network Connections. The
status appears to the right of your Wireless Network Connection. If the client adapter is authenticated,
the status reads, “Authentication succeeded.” The status line also indicates if the authentication attempt
fails.
