      If you don't remember your router login information, there are two solutions:

      Method 1: Factory reset (hard reset)

      1. Find the button on the back of the router. Reset (usually it is recessed into the body).
      2. Take a paper clip or a toothpick and press and hold the button 10-15 secondsuntil the indicators start flashing.
      3. Release the button and wait for the reboot (1-2 minutes).

    • 📡 The Wi-Fi network name will return to the default (Xiaomi_XXXX).

      If you have previously linked the router to an account Xiaomi, you can restore access without resetting:

      1. Open the app Mi Wi-Fi.
      2. Click on the router icon → Forgot your password?.
      3. Follow the instructions to recover via email or phone.

      This method does not work on all firmware versions. If the option is missing, use hard reset.
