Configure 802.1x EAP-TLS WPA-Enterprise Wi-Fi on your Access Point

• A Certificate Authority
• A RADIUS server
• A properly configured Access Point (AP)
• A process for distributing the CA certificate and enrolling clients. This is usually handled via a Mobile Device Management (MDM) enrollment of client devices

Protect a Wi-Fi Resource in Smallstep

1. Sign into Smallstep. Under the Protect tab, go to Wi-Fi and Add a Wi-Fi resource.

   You’ll need to supply the Wi-Fi SSID you’ll use for WPA3 Enterprise and your public-facing (WAN) IP address, so our RADIUS server can identify requests from your network.

2. When you’re finished, if you're using a Smallstep-managed RADIUS server, you’ll see your RADIUS server details. Use these details when you configure your Access Point.

General Instructions for Configuring 802.1x EAP-TLS on any Access Point

• Security Protocol: WPA2 Enterprise or WPA3 Enterprise
• RADIUS server information (provided by Smallstep)
  • RADIUS server IP
  • RADIUS server port
  • RADIUS server shared secret
  • RADIUS accounting port
