Changing the password on a Xiaomi Wi-Fi router is a basic but critical procedure for securing your home network. Many users neglect this step, leaving it at factory settings, leaving them vulnerable to hackers or simple traffic hijacking. Owners of routers from the Chinese giant often encounter nuances in the interface, which can be in English or Chinese, leading to additional questions.
The process of updating the access key does not require in-depth technical knowledge, but it is important to follow the sequence of actions to avoid losing access to the device. Change password This will forcibly disconnect all connected devices, so you'll need to reauthorize your smartphones, laptops, and smart devices. In this article, we'll cover all available methods in detail: via a computer browser and via a mobile app, which significantly simplifies ecosystem management.
It is worth noting that firmware interfaces may differ slightly depending on the model of your router, whether it is Xiaomi Mi Router 4A, Mi Router 3G or newer versions with Wi-Fi 6 support. Despite the visual differences, the operating logic remains the same for all devices in the line. The key is to correctly determine the encryption type and select a secure character combination that is difficult to brute-force.
Preparing to change security settings
Before making any changes to your router configuration, make sure your management device (laptop or smartphone) has a stable connection to the router. It's best to perform the configuration via cable connection (LAN), as changing the Wi-Fi password will interrupt your connection, and you may lose access to the web interface if the process is interrupted. If this isn't possible, use Wi-Fi, but be prepared for your phone's internet connection to be lost after saving the settings.
You will also need to know the login address for the control panel. For most devices Xiaomi And Redmi the standard address is 192.168.31.1 or domain name miwifi.comIf you've previously changed these settings, use the current IP address. Also, make sure you have the current administrator password, which is often (but not always) the same as your Wi-Fi network password.
It's important to prepare a new password in advance. It must meet modern security standards: be at least eight characters long and include uppercase and lowercase letters, numbers, and special characters. Using simple combinations like "12345678" or your date of birth will render your password ineffective, even if you use a modern encryption protocol.
Logging into the Xiaomi router's web interface
The first step is to log in to the control panel. Open any modern browser (Chrome, Safari, Firefox) and enter your router's IP address in the address bar. Most often, this is 192.168.31.1If the page doesn't load, check your network adapter settings—the IP address should be obtained automatically (DHCP). After visiting the address, you'll see a welcome screen asking you to enter your administrator password.
Enter the current password. If you're setting up the router for the first time, the system may prompt you to create a new administrator password or use the Wi-Fi password. Be careful: these are two different settings, although users often conflate them. Administrator password gives you full control over your device, while the Wi-Fi password is only needed to connect to the wireless network.
⚠️ Warning: If you enter the wrong administrator password three times, the system may temporarily block access or require confirmation through the linked Mi Account. Please be careful when entering your password.
The interface may be presented in English or Chinese unless you selected Russian during initial setup. In this case, use the icons and button layout as a guide. Key sections usually have a similar structure: network status, Wi-Fi settings, and system settings. Changing the language is often as easy as going to the section Status or Settings and select the flag of the desired country.
What to do if you forgot your administrator password?
If you've lost your password, the only way to regain access is to reset the router to factory settings. Find the hole marked "Reset" on the router's case, press it with a paperclip, and hold it there for 5-10 seconds until the indicator light flashes. After this, the router will be as good as new.
Change your password via a web browser (PC and mobile)
After successful authorization, you'll be taken to the main status page. This displays the current speed, number of connected devices, and network status. We need to find the section responsible for wireless settings. Depending on the firmware version (MiWiFi OS), this section may be called Wi-Fi Settings, Wireless or simply Settings with an antenna icon.
In the menu that opens, find the field marked as Wi-Fi Password or EncryptionThis is where the access key is stored. Delete the old characters and enter a new combination. Make sure the encryption type is selected. WPA2-PSK or WPA3-PSK (for new models). Using the outdated WEP standard or an open network (None) is strongly discouraged, as data will be transmitted in clear text.
Below is a table with the main parameters found in this section:
| Parameter | Description | Recommended value |
|---|---|---|
| SSID | The name of your Wi-Fi network | Unique name (not personal) |
| Encryption | Data protection type | WPA2-PSK / WPA3 |
| Password | Access key | Complex, >10 characters |
| Hide SSID | Hiding the network | Disabled |
After entering your new password, be sure to click the button Save or Apply (often indicated by a green checkmark). The router will warn you that changing the settings will result in a disconnection. Confirm the action. Now your router Xiaomi distributes the network with a new security key.
☑️ Verification after changing your password
Using the Mi Wi-Fi app
For smartphone owners, control is via the official app Mi Wi-Fi (or Xiaomi Home) is the most convenient method. It allows you to change settings at any time and from anywhere in the world if your router is connected to the cloud. Download the app from Google Play or the App Store, log in with your Mi account, and add your router if you haven't already.
In the main application window, select your router from the list of devices. On the status screen, find the item Wi-Fi Settings or simply the name of your network. Clicking this will open a menu where you can change not only the password but also the network name (SSID) and set up guest access. The app's interface is more user-friendly and is often fully translated into Russian.
The advantage of the mobile method is automatic synchronization. After changing your password in the app, your phone may prompt you to automatically update your connection settings for the current network. This eliminates the need to manually enter long character combinations on your smartphone's keyboard, which is especially important for complex passwords.
Setting up dual-band networks (2.4 GHz and 5 GHz)
Modern routers Xiaomi Supports operation in two frequency bands: 2.4 GHz and 5 GHz. Users often wonder: do they need to change the password for each band separately? By default, many models have the "Dual-Band Integration" feature enabled, where the router broadcasts a single network name and automatically selects the optimal frequency for the client.
If the network aggregation feature is disabled, you will see two separate networks (for example, MyHome And MyHome_5G). In this case, the web interface will have separate password entry fields for each range. Recommended Set the same passwords for both ranges to avoid confusion when connecting new devices, but it is better to make the network names (SSID) different to understand which frequency you are connected to.
The 5 GHz band offers higher speeds and is less susceptible to interference, but has a shorter range. The 2.4 GHz band penetrates walls better, but is often overloaded by neighboring routers. Properly setting passwords on both channels ensures that neighbors don't hog your channel and slow down your internet.
Problem solving and security
After changing the password, some devices may refuse to connect, displaying the error "Failed to connect" or "Authentication error." This is normal, as the old key is stored in the device's memory. Find your network in the list of available Wi-Fi networks, tap it, and select "Forget Network," then enter the new password.
Also worth paying attention to is the function WPSMany Xiaomi routers have a button for quick connection without entering a password. From a security standpoint, this feature is better. turn off in the settings, as it's vulnerable to brute-force attacks. If you don't need to constantly connect new devices using the push-button, keep WPS disabled.
⚠️ Note: The interface and menu layout may change after updating your router's firmware. If you can't find the options described, check for updates or refer to the official documentation for your specific model.
Regularly changing your password (e.g., every six months) and updating your router firmware are the best ways to protect yourself from unauthorized access. Don't use the same passwords for your Wi-Fi and personal online accounts. A unique access key is key to maintaining peace of mind in your home's digital space.
Why doesn't my Xiaomi router save settings?
Sometimes settings aren't saved due to a full browser cache or an unstable connection. Try using incognito mode or a different browser. Also, make sure your router has enough free memory.
Can I change my password if I'm not connected to Wi-Fi?
Yes, this is possible, but only if you have access to the web interface via a LAN cable or if you're connected to a guest network that isn't affected by the changes. Without a physical connection to the router (direct or via cable), you can't change security settings.
What is the most secure password for Xiaomi?
A strong password should contain at least 12 characters, including uppercase and lowercase letters, numbers, and special characters (e.g. K7#mP9$xL2!q). Avoid dictionary words and keyboard sequences.
What should I do if I lose internet access after changing my password?
Most likely, your PPPoE or DHCP settings have been reset if you changed other parameters in addition to the Wi-Fi key. Check the connection status in the "Internet" or "WAN" section. If you only changed the Wi-Fi password, make sure you entered it correctly on the client device.
Does changing your password affect your internet speed?
Changing your password itself doesn't affect speed. However, if you simultaneously change the encryption type (for example, from WPA2 to WPA3) or the frequency channel, speed may change. WPA3 is more secure, but older devices may perform slower or not connect at all.
Do I need to reboot my router after changing the password?
Usually routers Xiaomi The settings are applied immediately. However, if you notice network instability or devices are unable to connect, we recommend rebooting via the web interface or the power button.
