Xiaomi router owners often find themselves needing to change their wireless network access key. This may be due to a desire to strengthen safety local network, suspect that neighbors are using your internet, or after purchasing a used device. Changing the password is a basic but critical procedure that every home network administrator should be able to perform. Modern routers of this brand offer user-friendly interfaces, but the process has its nuances.
Unlike standard procedures on other devices, the ecosystem Xiaomi This may require using a mobile app or a web interface with a Chinese menu. It's important to understand that changing wireless network settings will temporarily disconnect all connected devices. Therefore, before attempting this, ensure you have access to the admin panel and are ready to reconnect your devices to the updated network.
In this article, we'll detail all the available methods for changing the encryption key: via a computer browser, via the official smartphone app, and even a factory reset in an emergency. We'll also cover the interface features. miwifi.com and a classic IP address, and we will also pay attention to choosing a reliable encryption algorithm to protect your data.
Preparing to change router security settings
Before making any changes to your router's configuration, it's important to perform a few preparatory steps. This will minimize the risk of losing access to your device or freezing the system during setup. First, make sure your device (computer or smartphone) is connected to the Xiaomi router. This can be done either via a LAN cable, which is the most reliable option, or via your current Wi-Fi network.
You'll need to know the control panel login address. This is the default for most Xiaomi models. 192.168.31.1 or domain name miwifi.comIt's also critically important to remember the administrator password. If you recently installed the router and haven't changed the password for logging into the settings, it may be the same as the Wi-Fi password or the default one (often blank or "admin," although newer Xiaomi firmware sets the admin password during initial setup).
It's a good idea to prepare the new password you plan to set in advance. It should meet security requirements: be at least 8 characters long, include mixed-case letters, numbers, and special characters. Write it down on paper or in a secure password manager to avoid losing access to the network immediately after changing it.
Login to the control panel via the web interface
The most common way to change network settings is to use your router's built-in web interface. This method is universal and works on both Windows and macOS computers, as well as mobile devices, if you open the browser in desktop mode. Open any modern browser (Chrome, Firefox, Safari, or Edge) and enter your router's IP address in the address bar.
After entering the address 192.168.31.1 The system will request authorization. Enter the administrator password. If you are logging in for the first time, the router may prompt you to complete a quick setup or take you directly to the main menu. The interface may be in English or Chinese, depending on the firmware version and region of the device. Newer global versions often include Russian, which can be selected in the upper right corner or in the section Settings.
⚠️ Attention: The Xiaomi web dashboard interface is frequently updated. The layout of menu items may vary slightly depending on the firmware version. If you don't see the items described below, look for similar sections related to "Wireless," "Wi-Fi," or "Common Settings."
After successful authorization, you'll be taken to the main status page, which displays the number of connected devices and internet speed. To change the password, go to the settings section. This is usually indicated by a wrench or gear icon. In the menu, select the Wi-Fi settings option.
Step-by-step password change in the settings menu
While in the settings section, find the tab Wi-Fi Settings or Wi-Fi settingsHere you can see the main wireless network parameters: network name (SSID), operating mode, and security key. Depending on the router model (e.g., Xiaomi Mi Router 4A, 4C, AX3600), the interface may offer separate settings for the 2.4 GHz and 5 GHz bands or combine them into a single network with smart switching.
☑️ Check before changing your password
Find the field labeled as Password, Key or PasswordIn older versions of the interface, it may be called "Wireless Password." Enter the new key you created there. Make sure the correct encryption type is selected—it is recommended to use WPA2-PSK or WPA3 (if the device supports it), as they provide the best protection against data interception.
After entering the new value, scroll down the page and click the button Save or ApplyThe system will warn you that changing the settings will disconnect the connection. Confirm the action. The router will reboot the wireless module, and after 10-20 seconds, the network will appear in the list of available networks with a new name (if you changed it) and a new password.
Some Xiaomi firmware versions have a "Dual-band integration" feature. If it's enabled, you change the password for both frequency bands at once. If the bands are separate, don't forget to change the password in the "Dual-band integration" tab as well. 5G Wi-Fiso that devices that support high speeds can also connect.
Using the Mi Wi-Fi mobile app
Xiaomi has developed a special application for smartphone users. Mi Wi-Fi (available on Google Play and the App Store). This method is often more convenient, especially if you don't have a computer nearby. The app allows you to manage the router remotely if you've previously linked the device to your Mi Account. However, it's best to be within range of the network for the initial setup.
After launching the app and logging in, select your router from the list of devices. The main screen displays the network status and a list of connected clients. To change the password, go to Settings (Settings) - usually an icon in the upper right corner or in the bottom menu. Next, select Wi-Fi Settings.
What should I do if the app doesn't see the router?
Make sure your smartphone is connected to the router's Wi-Fi network. If you're trying to control it remotely, ensure remote control is enabled in the web interface and that the router is linked to your Xiaomi account. Also, check the app's local network access permissions in your iOS/Android settings.
In the menu that opens, you'll see a field for changing the password. Enter the new key and click the save button. The app may prompt you to scan a QR code to quickly connect guests—this is a convenient way to share access without having to dictate a complex password. After applying the settings, your phone will lose connection to the router, and you'll need to reconnect using the new information.
The advantage of the mobile app is the ability to manage guest mode. You can create a separate network for guests with limited access to your local files and printers, setting a separate, simpler password for it. This improves overall security. cybersecurity your home infrastructure.
Setting up encryption and network security
When changing your password, it's crucial to pay attention to the encryption algorithm. Xiaomi router settings usually offer options. No Encryption (open network), WEP (outdated and unsafe), WPA/WPA2-PSK And WPA3-SAESelecting the wrong option can result in either a vulnerable network or the inability to connect older devices.
The optimal choice today is WPA2-PSK with AES encryption. This standard is supported by the vast majority of devices released in the last 15 years. If you have the latest technology (smartphones and laptops from 2020-2026) and a router that supports Wi-Fi 6, you can try the mode. WPA3, which provides protection even against brute-force password guessing.
| Encryption type | Security | Compatibility | Recommendation |
|---|---|---|---|
| WEP | Low (hack in minutes) | Very high | Do not use |
| WPA-PSK (TKIP) | Average | High | For older devices only |
| WPA2-PSK (AES) | High | Very high | Recommended standard |
| WPA3-SAE | Maximum | New devices only | For advanced users |
It is also worth checking the status of the function in the security section WPSWPS technology allows you to connect to Wi-Fi by pressing a button, but it has known vulnerabilities. Security experts recommend disable WPS in the router settings to prevent remote guessing of the PIN code by intruders.
Reset settings and restore access
If you've forgotten your administrator password and can't access the control panel, or if your router is unstable after changing settings, your only option is a factory reset (hard reset). This procedure will return the device to its out-of-the-box state, erasing all user configurations, including provider settings.
To perform a reset, find the hole marked on the router body ResetIt's usually located on the back panel near the LAN ports. You'll need a thin object, such as a paperclip or toothpick. With the router turned on, press and hold the button inside the hole for 5-10 seconds. The lights on the router should flash or go out, indicating the reset process has begun.
⚠️ Attention: After resetting, your Xiaomi router will revert to the factory Wi-Fi password, which is located on a sticker on the bottom of the device (usually a combination of numbers and letters). The administrator password will also be reset, and the system will prompt you to create a new one the first time you log in.
After rebooting, connect to the open Xiaomi network (the name is also indicated on the sticker) and go to the address 192.168.31.1The initial setup wizard will launch, where you will need to select the connection type (PPPoE, Dynamic IP, etc.), enter your provider information, and reset the Wi-Fi network name and password.
Common problems and their solutions
Users may encounter various difficulties when changing their password. One common issue is that the device fails to connect to the network after changing the password, displaying the error "Incorrect password" or "Unable to connect." In this case, find your network in the list on your smartphone or laptop, select "Forget Network," and re-enter the password.
Another situation: the password has been changed, but the internet connection is gone. This could be due to you accidentally changing other settings during the process, such as MAC filtering or Wi-Fi channels. It's also worth checking whether your ISP has blocked access due to a MAC address change (if you cloned it), although this rarely happens when simply changing the Wi-Fi password.
If your router interface is unresponsive or the settings page takes forever to load, try clearing your browser's cache or using incognito mode. In rare cases, changing your computer's DNS servers to public ones (such as Google's) may help. 8.8.8.8) to avoid problems with name resolution within the local network.
Why doesn't my Xiaomi router save my new password?
This could be due to a firmware error or configuration memory overflow. Try updating the router's firmware via the web interface. Also, make sure the new password doesn't contain characters that the system might interpret incorrectly (although standard ASCII characters usually don't cause problems). A hard reset might help as a last resort.
Is it possible to change the password if there is no internet from the provider?
Yes, you can. The local network works regardless of whether you have access to the global network. The main thing is that your device is connected to the router via cable or Wi-Fi. You will be able to access the settings and change the password, but the settings pages may take longer to load as the router tries to check for updates.
How can I secure my network from my neighbors other than with a complex password?
Use SSID hiding (the network name is not broadcast), configure MAC address filtering (allow only your devices), disable WPS, and regularly check the list of connected clients in the Mi Wi-Fi app. You can also limit the speed for unknown devices or block them completely.
Does changing your password affect your internet speed?
Changing your password itself doesn't affect speed. However, if you simultaneously change the Wi-Fi channel from "Auto" to a channel crowded by neighbors, or change the channel width, speed may change. It's recommended to leave channel settings on automatic or manually select the least crowded frequencies.
What should I do if I forgot my administrator password after a change?
If you've changed your control panel password and forgotten it, restoring it without resetting the settings is impossible for security reasons. The only option is to press the Reset button for 10 seconds. After this, the router will return to factory settings, and you'll have to set up your internet connection again.
