Changing the standard security settings is the first and most important step after buying any network equipment. Xiaomi routers, popular for their availability and functionality, often come with factory passwords that are easy to guess or find in open databases. If you still use the combination listed on the sticker from the bottom of the device, your local network is at risk of unauthorized access.
The procedure for updating credentials may seem complicated only at first glance, but it does not require a deep knowledge of network technologies. In this article, we will discuss in detail how to change the password on the Xiaomi Mi Router router through the browser and mobile application, and also consider the nuances of encryption settings for maximum protection.
Changing your access key in a timely manner prevents traffic theft, device locking by attackers, and personal data leakage, and ignoring this step makes your home network vulnerable to Man-in-the-Middle attacks, especially if your router firmware hasn’t been updated in years. Let’s move from theory to practice and keep your connection secure.
Preparing for changes in security settings
Before making changes to the configuration of network equipment, you need to ensure a stable connection between your control device and the router. LAN-If you don't have that capability, make sure your smartphone or laptop is connected to the Wi-Fi network you plan to protect.
You will also need to know the login address to the control panel. For most Xiaomi Mi Router 4A, 4C, 3 Pro and other current versions, the standard address is 192.168.31.1 or the domain name miwifi.com. These details are often duplicated on the information sticker located on the bottom of the device.
It is important to prepare a new password in advance that will meet modern cryptography requirements, and it should be complex enough that it cannot be picked up by brute-force, but it should be memorable for you.
- 🔌 Connect the control device to the router via cable or Wi-Fi.
- 📝 Write down or remember a new complex password of letters and numbers.
- 🔍 Find out. IP-Default gateway address (usually 192.168.31.1).
- ⚡ Make sure your laptop or smartphone battery is charged at least 30 times%.
☑️ Pre-testing
Entrance to the web interface of router management
Open any modern browser on your device. Enter the address bar IP-If you've previously configured your device and changed the control port, the address may be different, such as having extra numbers after the dot. Press Enter and wait for the authorization page to load.
The system will ask for an administrator password. Note that this is not a Wi-Fi password, but a router's own settings access key. If you've installed a router recently and haven't changed that setting, it may match the wireless password or be empty if you've agreed to the default settings on your first run.
⚠️ Note: If you forget the administrator password, you can't restore it in an easy way. The only solution is to completely reset the device to factory settings using the Reset button.
Once you have successfully logged in, you will be taken to the main page of the control panel, the interface may be in Chinese or English, depending on the firmware version (Global or CN), the navigation is similar, the main points are usually marked with icons or standard terms like "Settings", "Status" or "Common Settings".
What to do if the page is not loaded?
Search for the Wi-Fi network settings section
Xiaomi's firmware interface may vary depending on the model. In newer versions of MIWiFi, the menu is often located at the top of the screen or as a sidebar. You need to find the wireless section. Look for tabs called "Wi-Fi Settings," "Wireless," "Wi-Fi settings," or an antenna icon.
There are usually two main tabs or blocks inside this section: one for setting the 2.4 GHz frequency, the other for 5 GHz. If your router supports Dual-band integration, the settings can be bundled together. However, for maximum compatibility with older devices, it is recommended to configure them separately.
Find a field labeled "Password," "Wi-Fi Key," "Password," or "Security Key." That's where the current access key is stored. The old value will be hidden by asterisks or dots. To change it, just click in the input field and erase the old characters.
- 📡 Find the menu "Wi-Fi settings" or "Wireless Settings".
- 🔄 Switch between tabs 2.4G and 5G, if they are separated.
- ✏️ Locate the field labeled"Password" or"Key".
- 👁️ Check the type of encryption – it should be installed in WPA2-PSK or WPA3.
Creating a strong password and setting up encryption
When coming up with a new access key, avoid obvious combinations such as sequences of numbers (12345678), dates of birth or simple words. WPA2 and WPA3 encryption algorithms used in modern Xiaomi routers are sensitive to letter registers, so using capital and lowercase characters makes it much harder to hack.
The optimal password length is 12 to 20 characters, and passphrase, a phrase composed of several random words separated by special characters, is considered a good practice, for example, a Blue$Coffee#Run99 design would be much more reliable than password2026.
Also make sure that the "Encryption" or "Security Mode" option selects a WPA2-PSK (AES) or WPA3-SAE value. Using an outdated WEP protocol or mixed WPA/WPA2 (TKIP) mode reduces overall network security and connection speed.
💡
Use a password manager on your smartphone or browser to save a new complex key, so you don’t have to remember it or write it down on a piece of paper that might get lost.
Save Changes and Reboot the Device
After you enter a new password and choose the type of encryption, you need to apply changes. Find the "Save", "Apply" or "OK" button, which is usually located at the bottom of the screen or in the upper right corner. In some versions of the interface, the system may require you to re-enter the administrator password to confirm actions.
When you save it, the router will reset the settings and restart the wireless module, which will take 10 to 30 seconds, at which point all the devices connected to the Wi-Fi will lose connection, which is normal behavior, indicating a successful configuration update.
If you were setting up from your phone or laptop wirelessly, you would need to reconnect to your Wi-Fi network using a newly created password. Computers connected via cable will retain access to the Internet and control panel without reconnecting.
| Parameter | Recommended value | Description |
|---|---|---|
| SSID (Name of the network) | Unique name | Don't use the standard"Xiaomi_xxxx", You better put your name on it. |
| Encryption | WPA2-PSK (AES) | It is the most compatible and secure standard for most devices. |
| Password Length | 12+ characters | Minimum length for resistance to selection. |
| Hidden SSID | No (False) | Hiding the network does not provide real security, but it makes it difficult to connect guests. |
⚠️ Note: After changing your Wi-Fi password, smart devices (lamps, sockets, cameras) may shut down. You will have to reconfigure each of them through the application, specifying a new access key.
Alternative method: setup via the Mi Wi-Fi app
For smartphone users, Xiaomi has developed a handy mobile application Mi Wi-Fi (available on Google Play and the App Store), which is often easier, especially if the web seems overloaded, and allows you to manage the router remotely, even when you are away from home, provided you pre-assign your account.
After installing the app and logging into your Mi Account, add your router by following the instructions on the screen. From the main menu, select your device. From the list of available actions, find "Wi-Fi Settings" or "Wi-Fi Settings".
Here you'll see the fields for the network name and password. Change them, click Save, and the router will automatically update the configuration. QR-code for fast connection of guests, which is a convenient alternative to dictating a complex password.
💡
The Mi Wi-Fi mobile application is the most convenient way to manage for beginners, as it automatically synchronizes changes and provides a clear interface without unnecessary technical details.
Problem Solving and Access to Admin
Sometimes users are faced with a situation where they forgot the password not from Wi-Fi, but from the router's settings. Unlike the wireless key, this password cannot be seen in the connection properties of the computer (admin/admin, Wi-Fi passwords are not suitable, only hardware reset remains.
On the back of the Xiaomi router, find a small hole that says "Reset." Take a paper clip or toothpick, press a button inside the hole and hold it for about 5-10 seconds until the system indicator flashes orange or yellow, which will start the process of restoring factory settings.
Once reset, the router will go back out of the box, and you will have to reconfigure your connection to the provider (PPPoE, L2TP, or Dynamic IP) and create new Wi-Fi passwords and admin panels, and all personal data and port settings will be deleted.
