How to Connect to Wi-Fi Using TTLS + PAP on Android

TTLS + PAP is a common enterprise-level Wi-Fi authentication method. This guide explains how to connect to such a network using an Android device.

Step-by-Step Instructions

  1. Open your Android device's Settings.
  2. Go to Network & Internet > Wi-Fi.
  3. Select the appropriate Wi-Fi network or tap Add network.
  4. Set the following parameters:

Configuration Details

  • EAP method: TTLS
  • Phase 2 authentication: PAP
  • CA certificate: Use system certificates or Do not validate
  • Domain: (if validating certs), radius.ironwifi.com
  • Identity: Your username
  • Anonymous identity: Optional, e.g., anonymous@example.com
  • Password: Your password

Finally, tap Connect to join the network.

Troubleshooting Tips

  • Ensure the RADIUS server supports TTLS and PAP.
  • Android 11+ enforces strict certificate validation—check your CA settings.
  • If the “PAP” option doesn’t appear, your device may not support it natively.

Security Note

While PAP is not secure on its own, it is safe when used inside the secure tunnel provided by TTLS. Always verify the server certificate when possible to avoid man-in-the-middle attacks.
