On the Security tab, choose the WPA radio button. OR: On the Security tab, choose the 802.1x radio button. Choose PEAP (EAP-GTC) from the drop-down menu. To use PEAP (EAP-GTC) security, the server must have WPA-PEAP certificates, and the server properties must already be set. Check with the IT manager. Click the Configure button. Select the appropriate network certificate authority from the drop-down list. Specify a user name for inner PEAP tunnel authentication:
| Check Use Windows User Name to use the Windows user name as the PEAP user name.
| OR: Enter a PEAP user name in the User Name field to use a separate user name and start the PEAP authentication process.
Choose Token or Static Password, depending on the user database. Note that Token uses a hardware token device or the Secure Computing SofToken program (version 1.3 or later) to obtain and enter a one-time password during authentication. Click Advanced and:
| Leave the server name field blank for the client to accept a certificate from any server with a certificate signed by the authority listed in the Network Certificate Authority drop-down list. (recommended)
| Enter the domain name of the server from which the client will accept a certificate.
The login name used for PEAP tunnel authentication, fills in automatically as PEAP-xxxxxxxxxxxx, where xxxxxxxxxxxx is the computer's MAC address. Change the login name if needed. Click OK. Enable the profile.
