DESCRIPTION
This field displays the user authentication method. Authentication is
the process of confirming the identity of a mobile station (by means
of a username and password, for example).
Check with your service provider if you are unsure of the correct
setting for your account.
Choose from the following user authentication methods:
• TTLS (Tunnelled Transport Layer Security)
• TLS (Transport Layer Security)
Note: Not all WiMAX Modems support TLS authentication.
Check with your service provider for details.
This field displays the type of secondary authentication method.
Once a secure EAP-TTLS connection is established, the inner EAP is
the protocol used to exchange security information between the
mobile station, the base station and the AAA server to authenticate
the mobile station. See the WiMAX security appendix for more
details.
This field is available only when TTLS is selected in the
Authentication field.
The WiMAX Modem supports the following inner authentication
types:
• CHAP (Challenge Handshake Authentication Protocol)
• MSCHAP (Microsoft CHAP)
• MSCHAPV2 (Microsoft CHAP version 2)
• PAP (Password Authentication Protocol)
Select the authentication mode from the drop-down list box.
This field is not available in all WiMAX Modems. Check with your
service provider for details.

connect to the Internet.
