Changing your password on your home wireless network is a basic but critical step to keep your data secure. Many Xiaomi users neglect this action after initially installing the router, leaving standard combinations that are easy to crack. If you’re thinking about changing your password on Xiaomi’s WiFi, you care about protecting personal traffic and connected devices.
The process of updating the access key does not require a deep knowledge of network technologies and takes only a few minutes. In this article, we will discuss in detail two main ways of completing the task: through a browser on a computer and through a convenient mobile application, you will learn how to properly configure encryption settings and avoid common errors that can lead to loss of communication with the router.
Why it is important to change your WiFi password regularly
Wireless network broadcasts data within range of the router, making it potentially accessible to outsiders. Standard passwords set by the manufacturer are often the same format or easy to guess. Attackers use special dictionaries to match these combinations in seconds. Changing the password to a unique and complex code makes it much more difficult to crack.
In addition to protecting against Internet traffic theft, it prevents unauthorized access to your local network. In a Xiaomi smart home, the router can be connected to cameras, sensors and appliances. If an outsider gets into the network, they can theoretically gain control of these devices. Regular updating of credentials is the first line of defense.
⚠️ Note: If you notice that the Internet speed has dropped sharply or unfamiliar devices appear in the list of connected customers, immediately change your password and check the list of allowed devices. MAC-address.
You could give your password to guests, neighbors, or craftsmen who came to set up your appliances, and as time goes on, the circle of people who know your access key expands, and periodic password rotation allows you to limit the number of users to those who actually live in the apartment right now.
Preparation for the password change procedure
Before you make changes to your Xiaomi or Redmi router settings, you need to be prepared properly to avoid losing access to the administration panel. Make sure your device (smartphone or laptop) is connected to the router. This can be done either wirelessly or via WiFi. LAN-cable, which is a more reliable option.
You'll need to know the login address of the web interface. For most Xiaomi models, this is the same. IP-192.168.31.1 or the domain name miwifi.com. You also need an administrator password. If you've changed it before, use the new combination; if you haven't, look at the sticker at the bottom of the device, which often has a factory password to log in to your settings.
☑️ Preparation for network setup
It is recommended to create a new complex password in advance, which should contain at least 8 characters, including capital and lowercase letters, numbers and special signs. Using simple sequences like "12345678" or date of birth negates all efforts to protect.
💡
Write a new password in a safe place or use a password manager. Forgotten complex password to recover without resetting the router to factory settings is impossible.
Change password through the router web interface
The most versatile way to change security settings is to use a built-in web interface, which is suitable for all Xiaomi router models, including the Mi Router 4A, 4C, AX3600 series, and others. Open any browser on the connected device and enter the address 192.168.31.1 in the address bar.
Once you enter your administrator password, you'll be taken to the main menu. The interface may be in English or Chinese, but the structure remains similar. You'll need to find the section that handles your WiFi settings. Usually it's called Settings, then WiFi Settings, or just WiFi. In some firmware, it might be the Common Settings tab.
In the menu that opens, find the Password or WiFi Password field. Enter your new character combination. Pay attention to the Encryption field. For maximum compatibility and security, choose WPA2-PSK or the newer WPA3 if all your devices support it.
| Parameter | Recommended value | Description |
|---|---|---|
| SSID | Unique name | The name of your network that you can see when searching |
| Encryption | WPA2-PSK / WPA3 | Data encryption protocol |
| Password | 8+ characters (A-Z, 0-9) | Network access key |
| Hide SSID | Off (off) | Hide the web from search (not recommended) |
Once you have entered all the data, be sure to click either Save or OK (often marked with a green tick).The router will apply the settings and the wireless network will restart.All connected devices will be disabled, and you will have to re-enter a new password on each of them.
💡
After saving the settings, the router restarts the WiFi module. Automatic reconnection of devices will only happen if you update the saved password in their settings.
Set up through the Mi Home app
For users of the Xiaomi ecosystem, the most convenient way to manage is the Mi Home mobile app (or Xiaomi Home), which allows you to change your WiFi password in just one click, anywhere in the apartment. Make sure your smartphone is connected to the router you want to change your settings.
Run the app and find your router's card in the device list, which is usually at the top of the list or in the Devices section. Click on the router icon to go to the control menu. If the router doesn't show up, click + and add the device again, following the instructions on the screen.
From the router menu, select WiFi Settings or WiFi Settings. Here you will see the network name (SSID) and the current password. Click on the password field to edit it. Enter a new combination and press Save or Apply. The application will automatically send a command to the router.
- 📱 Open the Mi Home app on your smartphone.
- 📡 Select your router from the list of devices.
- 🔑 Go to WiFi settings and change your password.
- ✅ Click "Save" to apply the changes.
The advantage of the mobile method is that the application can offer to automatically update the password on the smartphone itself, so as not to enter it manually, but on other devices (laptops, tablets, IoT gadgets) you will have to enter a new access key again.
What to do if the app does not see the router?
Features of dual-band routers (2.4 GHz and 5 GHz)
Modern Xiaomi routers often support two frequency ranges: 2.4 GHz and 5 GHz. 2.4 GHz has a longer range, but less speed and is subject to interference. 5 GHz range provides high speed, but worse penetration through walls. When changing a password, it is important to understand how your router is configured.
If you have a Double Band or Dual Band enabled, you have one network with one name and one password for both frequencies, and the router decides how often to connect the device, and you change one password, and it works for all frequencies.
If the bands are separated, you will see two networks, such as MyWiFi and the Internet. MyWiFi_5G. Each band can have different password fields in the settings of the web interface or application. While it is technically possible to set different passwords, it is better to set the same password for both networks for ease of use, so as not to get confused when connecting gadgets.
⚠️ Warning: Older devices (smart light bulbs, sockets) often only work in the 2.4 GHz band. Make sure that after changing your password, you connect them to this network, otherwise they will not be able to contact the router.
With split bands, there may be separate tabs for 2.4G and 5G in the web interface. Check the settings in both tabs to make sure the password is changed wherever it is needed, especially if you plan to disable one of the bands in the future.
What to do if the password from the router settings is forgotten
Often, there is a situation where the user wants to change the WiFi password, but does not remember the password to log into the administration panel of the router. This is not a password from WiFi, but the administrator password that is requested when you log in to 192.168.31.1. Without it, you can not change the settings.
The only reliable way to restore access is to perform a full Hard Reset. There is a special hole on the case of Xiaomi routers, signed as Reset, which is usually recessed into the case to avoid accidental pressing.
Take a paper clip or a toothpick. When the router is on, press the button inside the hole and hold it for 5-10 seconds. The indicator on the router should flash orange, after which the device will restart. All settings, including the WiFi password and the administrator password, will return to the factory values specified on the sticker.
- 🔌 Find the Reset hole on the back panel.
- 📎 Press and hold the paperclip. 5-10 seconds.
- ⏳ Wait for the indicator to flash and reboot.
- 🔑 Log in using the data from the sticker.
After the reset, you will need to reset your Internet connection (enter your ISP login and password if PPPoE is used) and set new names and passwords for WiFi networks, which is a good reason to remove all the tails and set up the network from scratch correctly.
💡
Hard Reset removes ALL settings, be prepared to re-enter data from your ISP and adjust parental controls or port skipping.
