### Using PEAP-MSCHAP V2 Security

To use PEAP-MSCHAP V2 security In the Atheros Client Utility, access the Security tab in the Profile Management window.

4. 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.
