How to find out the password from Wi-Fi on the router Xiaomi 4C: all the ways from simple to complex

Why Wi-Fi Password on Xiaomi 4C Can Be Lost

Xiaomi Router 4C is a popular device among users due to its stable operation, compact size and integration with the Mi Home ecosystem. However, even with such a reliable gadget, typical problems arise: a forgotten password from Wi-Fi, a lost data sticker or resets after a firmware update.

Unlike smartphones, where passwords can be restored via email or SMS, routers are more complex: there is no universal “forgot password.” But the Xiaomi 4C has some unique features that make it easier to do, such as the device supports recovery through the proprietary Mi Wi-Fi app (even without a network connection), and the web interface allows you to export a configuration with passwords. In this article, we will examine all the current methods, from the simplest to the radical (like resetting to factory settings).

• 🆔 Login / password for login - by default admin/admin or listed separately.

Important: If you have previously changed your password through settings, the data on the sticker will be irrelevant. However, if the router was reset to factory settings (for example, after firmware), factory credentials will recover. MAC-address – it is useful for linking the device in the Mi Wi-Fi application.

⚠️ Note: On some batches of Xiaomi 4C (Especially sold through informal channels, the sticker may be damaged or missing.

If the sticker is intact but the password doesn’t fit, try entering it in uppercase or with possible typos (e.g., an “O” instead of a “0”). Also check if your device has auto-replace characters on it when you type.

Method 2: Recover passwords through the Mi Wi-Fi app

The Mi Wi-Fi app (formerly Mi Router) is Xiaomi’s most convenient router management tool, allowing you to not only configure your network, but also view your current passwords even if you’ve forgotten them, and the main condition is that your smartphone must be connected to the router (at least via cable or guest network).
