Standard password on the Xiaomi 4 router: a full access guide

Owners of Xiaomi network devices often face the need to quickly configure or reconnect to the Wi-Fi network, but forget the authorization data set when you first activate. The factory password on the Xiaomi 4 router is critical information without which you can not get into the control panel of the router to change security settings. Unlike older models, where the keys were often universal, modern devices in the Mi Router 4, 4A, 4C and 4 Pro series use more advanced security algorithms.

If you’ve just unpacked a device or performed a hardware reset, you’ll need to find a unique character combination that’s usually shown on a sticker located on the bottom panel of the case. Chinese versions of devices may have different labeling than global models, which sometimes causes confusion among users. In this guide, we’ll go into detail about all the options for standard passwords, how to restore them, and how to bypass locks if access is lost.

Understanding the logic of Xiaomi MiWiFi security will not only help you log in, but also protect your home network from unauthorized access. We will look at scenarios where the standard key does not fit, and explain why this happens in most cases. Get ready to dive deep into the technical nuances of your router.

Where to find a standard password on the case and in the documentation

The first place to look when looking for credentials is the information sticker on the bottom of the router. On most models, such as the Xiaomi Mi Router 4A or 4C, the factory Wi-Fi password and administrator password often match and are labeled as "Password" or "PIN." A unique code consists of 8 or more characters and is generated individually for each device in the factory.

However, it is worth considering that some Chinese firmware versions may not have a password field or be replaced by a password requirement when you first sign in. In such cases, a standard numeric code simply does not exist in the usual sense. If the sticker is erased or unreadable, try looking for the original box - sometimes a duplicate of the information with characteristics is glued to the end of the package.

⚠️ Note: If the sticker says “No password” or the field is empty, this means that the device requires an initial setup via a mobile application or web interface without using a factory key.

For devices released in different years, the labeling format may change, and the following table helps to identify the type of password depending on the model and firmware version:

Take a picture of the sticker from the back of the router immediately after you buy it and save it to the cloud. Paper labels tend to fade and wear off over time.

Entering the web interface by IP-address 192.168.31.1

To access the router settings, you need to connect to its network and enter the correct IP-The standard address for Xiaomi devices is 192.168.31.1, although in some rare cases, especially on re-flashed devices, it can be changed to miwifi.com. In the browser address bar (Chrome, Safari, Opera), enter this address and click Enter.

When you go to the address, you will see the MiWiFi OS Welcome page. If the router is new or reset, the system will ask you to create a new administrator password. If the device has already been in use, it will ask for a login password that may have been set by the previous owner or you previously. Don't confuse this password with the Wi-Fi key, although they are often identical initially.

In case the page doesn't load, check your computer's network adapter settings. IP-The address and gateway are automatically obtained through DHCP. Static IP-The address manually written in another subnet will block access to the control panel.

Differences between Wi-Fi Password and Administrator Password

Many users mistakenly believe that the password to connect to a wireless network and the password to log into the router settings are always the same. On Xiaomi Mi Router 4 devices, by default, these keys are indeed synchronized for user convenience. However, once you get into the settings, the system allows (and strongly advises) to share this data for increased cybersecurity.

The Wi-Fi password (WPA2-PSK) is used by all guests and devices to access the Internet. The Admin Password gives you complete control over network configuration, including changing the DNS, port scrolls, and traffic filtering. If an attacker learns the administrator password, they can redirect your traffic to phishing sites without even knowing the Wi-Fi password.

You should use different character combinations. For Wi-Fi, you can use a simpler, but longer password that is easy to type from your phone. For admin, use a complex string with registers and special characters that no one can find by brute force.

⚠️ Warning: Never use simple combinations like "12345678" or "admin" to protect the administrative panel, which takes less than a minute to crack when using automatic scripts.

Resetting procedure to factory settings (Hard Reset)

If the standard password doesn't fit and you don't remember the changed key, the only solution is to completely reset your settings. This procedure will return the Xiaomi Mi 4 router to the state it was when it left the assembly line.

Turn the router on and wait until the load is complete (the indicator should be on a straight light). Take a paper clip or a thin needle, press a button inside the hole and hold it for 5-10 seconds. The indicator will start flashing orange, which signals the beginning of the recovery process.

The discharge process:


1.Push Reset.




2 Hold 5-10 seconds until the indicator flashes.




3. Release the button.




4. wait 2-3 minutes until a full reboot.

Once the indicator lights up in blue (or white, depending on the model), the router will be ready for the initial setup. All user data, including provider logs and network names, will be deleted. You will have to re-enter the PPPoE or dynamic IP data provided by your ISP.

Configure via the Mi WiFi mobile application

Modern Xiaomi routers, including the 4A and 4 Pro series, are closely integrated with the smart home ecosystem. Mi WiFi (or Mi Home) is often required to manage the device, available on the App Store and Google Play, which is especially convenient if you do not have access to your computer or the web interface is not working properly.

The app allows you not only to set a password, but also to manage guest mode, check Internet speed and even update the router's firmware. To pair the phone must be connected to the router's Wi-Fi network. If the network is protected, the application will request a password; if this is the initial setting, it will suggest creating a Xiaomi account.

Using the app gives you the advantage of automatically backing up your settings to the cloud, and if you forget your password in the future, you can restore the configuration by simply logging into your Mi Account without having to use complicated cable and browser manipulations.

💡

The Mi WiFi mobile application is the most reliable way to manage, as it allows you to restore access through your Mi Account, even if the admin password is lost.

Frequent access problems and their solution

Even if you know the right password, you may not be able to log in. One of the common reasons is browser cache. Old authorization data may conflict with the new router settings. Try opening the Incognito settings page or clearing the browser cache completely.

Another problem is the firmware version: In some Chinese versions of the Mi Router 4, the web interface may not display correctly in mobile browsers or require the installation of a plugin, in which case it is better to use the desktop version of the browser or a specialized application.

It’s also worth checking if your computer has blocked access to the local network. Some security programs flag login attempts as suspicious activity if the connection protocol is not protected by HTTPS (and HTTP is often used by default).

• 🔍 Check if the network indicator is blue – orange indicates no internet or configuration error.
• 🔄 Try using another browser (Firefox, Edge, Chrome) to rule out compatibility issues.
• 📡 Make sure your device is connected to Xiaomi router, not a signal extender or other Wi-Fi.
