Overview

When configuring the Cradlepoint WiFi for WPA2 Enterprise, it is helpful to be familiar with RADIUS authentication workflow.

Radius workflow: 

  1. Client initiates authentication to the Cradlepoint Router.

  2. Cradlepoint router prompts for username and password.

  3. Client supplies credentials.

  4. Client sends username and encrypted password to the Windows 2012 NPS RADIUS server.

  5. RADIUS server responds with Accept, Reject, or Challenge.


Radius Clients -  The Radius Client in this scenario will be the Cradlepoint router.

Windows 2012 NPS radius configuration will also include defining a "Network Policies"
