How to Connect to Wi-Fi Using EAP-PEAP on Android

EAP-PEAP (Protected Extensible Authentication Protocol) is a secure Wi-Fi authentication method that uses a TLS tunnel to protect username and password credentials. It is widely supported on Android devices.

Requirements

• Network SSID (Wi-Fi name)
• Username and password (provided by your network admin)
• Optional: CA certificate (if certificate validation is enforced)

Step-by-Step Instructions

1. Go to Settings > Network & Internet > Wi-Fi.
2. Select your Wi-Fi network or tap Add network.
3. Tap Advanced options to expand security settings.
4. Configure the following options:

Wi-Fi Configuration for EAP-PEAP

• EAP method: PEAP
• Phase 2 authentication: MSCHAPV2
• CA certificate: Use system certificates (recommended) or Do not validate if testing
• Domain: (if validating certs) radius.ironwifi.com
• Identity: Your username (e.g., email or login ID)
• Anonymous identity: Optional, e.g., anonymous@example.com
• Password: Your account password

Once everything is set, tap Connect.

Troubleshooting Tips

• Make sure your username and password are correct.
• If the device shows “Connected, no internet,” the RADIUS server may be rejecting credentials.
• Ensure the RADIUS certificate is valid and includes the correct domain (for Android 11+).

Security Note

EAP-PEAP provides strong encryption by creating a TLS tunnel before transmitting your credentials. Always prefer certificate validation to prevent rogue network attacks.
