3. Hold the Reset button (pin hole on the back).
4. While holding reset, power on the router. Keep holding for 15 seconds.
5. The Power LED should flash slowly (Recovery mode).

• You experience frequent disconnections.
• The web interface is slow or unresponsive.
• You need new features (e.g., repeater mode stability).
• Security vulnerabilities are announced.

• Handler Functions: The binary uses a mapping of URL routes to C functions (e.g., handler_r_password_change).
• Validation: Input validation is often performed client-side (JavaScript) rather than server-side. Disabling JavaScript in a browser or sending raw HTTP requests using tools like curl or Burp Suite bypasses these restrictions.
• Encryption: Admin passwords are often stored in clear text or weakly hashed in the NVRAM configuration (nvram show).
