Changing your wireless password is a basic step to keep your home Internet secure. Many Xiaomi routers ignore standard factory settings, making their network vulnerable to unauthorized connections. If you recently purchased a device or just decided to update your access data, the procedure will take only a few minutes.
Modern routers from the Chinese giant, whether Mi Router 4A or flagship AiRouter AX3600, have an intuitive management interface. However, the lack of Russification in some versions of firmware or the specifics of the mobile application can raise questions for beginners. In this guide, we will discuss all the current ways to change the encryption key, eliminating possible errors.
It's important to understand that once you change your password, all your devices -- smartphones, laptops, smart TVs -- will lose their network connection, and you'll need to re-enter the new code on each gadget, so write the new data in a safe place right after you've set up so that family members don't have to block Internet access.
Preparing for changes in security settings
Before starting the procedure, make sure that your control device (smartphone or computer) has a stable connection to the router. LAN-cable, because it ensures that there are no breaks in the configuration process. If this is not possible, make sure that your phone is connected to the router's Wi-Fi network, not to the mobile Internet.
You will also need credentials to log into the admin panel. Xiaomi devices often don’t have a password to log in to the web interface, or it matches the Wi-Fi password if you set it up the first time you set it up. In some cases, the standard admin code is used.
☑️ Preparation for setting up the router
It is recommended to prepare a new password in advance, which will meet modern security standards, it must contain at least 8 characters, include capital and lowercase letters, numbers and special signs. Using simple combinations like 12345678 or date of birth reduces network security to zero, allowing attackers to easily pick up the key by brute force.
Entrance to the router control panel
There are two main ways to get into the router settings: through a web browser on a computer or phone, and through the Mi Home mobile application. The web interface provides more advanced features and detailed settings, while the application is convenient for quickly changing parameters on the go.
To enter through the browser, open any browser (Chrome, Safari, Opera) and enter in the address bar IP-The standard address for most Xiaomi models is 192.168.31.1 or the domain name miwifi.com. After going to the address, the system will ask for the administrator password. If not, try leaving the field blank or using a Wi-Fi password.
⚠️ Note: If you forget your administrator password and it doesn't match the Wi-Fi key, the only way to access it is to reset the router completely to factory settings. 10-15 seconds.
When using the Mi Home mobile app (formerly Mi WiFi), the process looks different. Launch the app, select your router from the list of devices. If the interface is in Chinese, which is often found in domestic versions, look for the settings icon (usually three dots or a gear) in the upper corner. Next, go to the section responsible for settings for the wireless network.
Changing password through the web interface
Once you have successfully logged in to the web panel, you will see the main screen with the network map and connection status. We need to find the section responsible for setting Wi-Fi. Depending on the firmware version (green or blue interface theme), this item may be called Wi-Fi Settings, Wi-Fi settings or just displayed as the name of your network.
In the menu that opens, find a field labeled Password, Key, or Password. Delete the current value and enter the character combination you have invented. Make sure you choose the type of encryption WPA2-PSK or WPA3, because they provide the best protection for the data being transmitted. Old protocols like WEP are considered outdated and insecure.
Why can the interface be in Chinese?
Once you have entered a new value, scroll down and press the save button, which can be called OK, Save or Apply. The system will alert you that the connection will be broken. Confirm the action. The router will restart the wireless module, and in a few seconds the network will appear in the list of available with a new name or requiring a new access key.
Use of the Mi Home mobile application
Owners of the Xiaomi ecosystem often prefer to manage the network via a smartphone. Mi Home app allows you to change the password without having to open a browser. After logging in to your account and selecting a router, go to the settings section. The interface may vary depending on the region selected in the application (China, Europe, Russia).
Find Wi-Fi Settings, and you'll see two fields here if you're bi-band: 2.4 GHz and 5 GHz. You can set the same passwords for both bands, which will make it easier to connect the devices, or you can set different passwords for load sharing. Type a new key into the appropriate field.
- 📱 Make sure your phone is connected to the internet (via a mobile network or another router’s Wi-Fi) as the current connection will break once the password is changed.
- 🔐 The application may request confirmation of the operation through SMS or push notification for security.
- 🔄 After saving the settings, the router can flash indicators for a short time, signaling the restart of the wireless module.
The app's feature is that you can create a guest network, you can set up a separate password for guests without revealing the main key to your home network, and it's a useful feature to control how third-party devices access your local resources, such as network storage or printers.
Set up a dual-band network (2.4 GHz and 5 GHz)
Modern Xiaomi routers support two frequency bands. 2.4 GHz range provides greater coverage but lower speed and is subject to interference from neighbouring networks and microwaves. 5 GHz range offers high speed and stability, but has a shorter range and worse passes through walls.
When changing the password, you can configure the networking (Smart Connect) or separate networks. SSID. In the first case, the router chooses the optimal frequency for the client, and the password will be the same. MyHome_5G), Passwords can be set individually for each.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Transmission speed | Up to 450 Mbps | Up to 1733 Mbps |
| Signal range | Tall. | Medium |
| Permeability of walls | Good. | Low. |
| Level of interference | High-pitched | Low. |
💡
For smart home (lamps, sockets) use a 2.4 GHz network, as many IoT devices do not support 5 GHz.
It is recommended to set complex unique passwords for each band if you use separate SSIDs. This will add an additional layer of network segmentation. However, for most users, it is more convenient to use the Dual-Band Integration feature, which hides the technical part and provides a single entry point with automatic frequency switching.
Common mistakes and ways to solve them
When you change your password, you often have problems that are easily solved, and one of the common mistakes you make is to type a password that doesn't have the right keyboard or accidentally turn on Caps Lock. The system won't give you an error when you type it, but you can't connect the devices.
Another common situation is that the router freezes after settings are applied. If the indicators are not burning as usual, or the network is gone and does not appear, try to turn off the power of the device for 10-15 seconds. Forced reboot often resolves software failures that occur when maintaining a new configuration.
⚠️ Warning: Do not interrupt the settings update by turning the router off the socket when the system indicator flashes. This can damage the firmware and require recovery through the console.
If you change your password but a device (like an old laptop or tablet) refuses to connect, try to “forget” the network on the device itself. delete the network profile from the device’s memory and reconnect by entering a new key. Old saved configurations may conflict with new security settings.
Additional measures to protect the Wi-Fi network
Changing your password is just the first step. To maximize the protection of your network, Xiaomi recommends activating additional security features. In the control panel, find the Security or Security section. MAC-Addresses that will allow only trusted devices to connect, even if the attacker learns the password.
Also worth checking for firmware updates: the manufacturer regularly releases patches that close security vulnerabilities; Automatic updates can be enabled in the system settings to keep the router up to date; this is critical to preventing remote attacks.
- 🛡️ Turn off the function. WPS, It is a known vulnerability that allows you to easily hack the network.
- 👁️ Regularly check the list of connected customers in the application or web interface.
- 🚫 Use a guest network for visitors by isolating them from your personal files.
Remember that the reliability of your network depends not only on the complexity of the password, but also on a comprehensive approach to setup. Regular audit of connected devices and timely updates of software will make your home network an impregnable fortress for uninvited guests.
💡
Install an internet speed checker app (like Speedtest) immediately after changing your password to make sure the new encryption key doesn’t slow down your connection speed.
