Changing your wireless password is a basic skill that every smart tech owner must master. Xiaomi routers often face the need to update their access key to protect your home network from unauthorized connections or simply after changing your provider. Wi-Fi security directly affects Internet speed and the safety of personal data transmitted over the network.
The process of updating the access key in the Mi ecosystem is quite flexible, you can perform the necessary actions both through the classic web interface from your computer and using the Mi Wi-Fi mobile application. It is important to understand that after changing the settings, all connected devices will need to reconnect again, entering new code.
In this article, we will discuss both methods in detail, paying special attention to the nuances of working with the MIWiFi shell, you will learn not only to change the password, but also to optimize the security settings so that your router works steadily.
Preparing for changes in security settings
Before making changes to the router configuration, make sure there is a physical or wireless connection to the device. To set up through the browser, you will need a laptop or PC connected to the Xiaomi router by a LAN cable or over the current Wi-Fi network. If you plan to use the smartphone, make sure it is also connected to a managed network.
Access to the admin panel is critical. By default, most Xiaomi Router 3, 4, 4A, AX3600 and others have an address for login that looks like 192.168.31.1 or the domain name miwifi.com. However, if you have reconfigured it before, the address may have changed. You can check the current gateway in your device's network settings.
You'll also need credentials to log in to the control panel, and if you set up your router yourself, this is the password you came up with when you first activated, and in some cases, if you lose your password, you'll have to reset your settings to the factory, which will return the standard authorization data you had on the bottom of the case sticker.
⚠️ Note: When you change your Wi-Fi password, the active connection to your router will be severed immediately after you save the settings. If you are setting up wirelessly, be prepared for the control page to stop loading, which is normal system behavior.
The method of changing passwords through the web interface
Configuring through the browser is considered the most reliable way, since it provides access to all hidden system parameters. Open any modern browser (Chrome, Firefox, Opera) and type in the address bar IP-The address of your router, usually 192.168.31.1. After pressing Enter, the system will ask for the administrator password.
Once you've successfully logged in, you'll be taken to the main status page, which shows the current CPU load, the number of devices connected, and the speed of the Internet. We're interested in the wireless network section. In MIWiFi, it's often labeled "Wi-Fi settings" or a wireless signal icon. Going there, you'll see the SSID name fields (2.4 GHz and 5 GHz).
In the Password field, delete old characters and enter a new combination. It is recommended to use complex passwords at least 12 characters long, including letters of different registers and numbers, which will protect your network from selecting the key using brute-force. Remember to click the "Apply" or "Save" button, which is usually located at the bottom of the page.
☑️ Pre-conservation checks
The system will warn you that changing the settings will cause the connection to break. Confirm the action. The router will restart the wireless module, and in 10-15 seconds the network will appear in the list of available with a new name or the same, but with a new access key.
Management through the Mi Wi-Fi mobile application
For users who prefer mobile control, Xiaomi has developed a specialized application Mi Wi-Fi, which is available for Android and iOS platforms, this method is especially convenient when there is no computer at hand. First, make sure that the application is installed and your phone is connected to the router network.
Launch the app and log in to your Mi Account. If the router is linked to your account, it will show up in your device list. Click on your router icon to go to the control panel. The application interface is more simplified than the web version, but contains all the necessary features for quick setup.
In the management menu, find the Wi-Fi Settings section, where you can change not only your password, but also your network name and mode of operation (e.g., combine 2.4 and 5 GHz bands into a single network), enter a new password in the appropriate field, and the application can suggest generating a complex password automatically, which is a good practice for improving cybersecurity.
💡
Use the Guest Network feature in the app if you have friends who come to you, allowing them to access the Internet without having to access the main smart home devices.
Once you have entered, click the save button in the top right corner. The app will alert you when you have a connection broken. Confirm the action. Now your smartphone will automatically try to reconnect to the network using the updated credentials.
Table of standard parameters of Xiaomi routers
To successfully set up, it is important to know the factory values that are used by default if the router has not been previously configured. Below is a table with the main parameters for popular models.
| Model router | default IP address | Standard Wi-Fi name | Location of the sticker |
|---|---|---|---|
| Xiaomi Router 4A | 192.168.31.1 | Xiaomi_XXXX | Lower part of the hull |
| Xiaomi Router AX3600 | 192.168.31.1 | Xiaomi_AX3600_XXXX | Lower part of the hull |
| Xiaomi Router 3G | 192.168.31.1 | Xiaomi_XXXX | Lower part of the hull |
| Xiaomi WiFi Power Plug | miwifi.com | Xiaomi-repeater-XXXX | Side-face |
Note that the suffix XXXX The name of the network usually corresponds to the last symbols. MAC-This helps you identify your router in apartment buildings, where there may be many networks with similar names.
Access problems and their solution
Often users are faced with a situation where the page 192.168.31.1 does not open. This can be due to several reasons. IP-address (DHCP) If you have a static adapter on your network. IP from another subnet, access to the router will be impossible.
Second, antivirus programs or firewalls on your computer can block access to local management addresses. Try temporarily disabling protection or adding a router address to exceptions. It's also worth trying another browser or incognito mode to eliminate the impact of cache and extensions.
⚠️ Note: If you have entered the wrong administrator password three times, the router’s security system may temporarily block the ability to log in to the router. 5-10 Don't try to find a password indefinitely.
If you lose access to the control panel completely, the only solution is a hardware reset. On the back of the router, find a hole that says Reset. Press it with a paper clip and hold it for about 5-10 seconds until the system indicator flashes orange, which will return all settings to factory settings.
What to do if the router does not see SIM-card 4G model)?
Choosing the optimal type of encryption
When changing a password, special attention should be paid to the type of encryption. In modern Xiaomi routers, it is recommended to use the standard by default. WPA2/WPA3 Mixed or simply WPA2 Personal: These protocols provide reliable protection for data transmitted.
Using outdated WEP encryption or open network (Open) makes your traffic visible to anyone within range of the signal.Attackers can intercept passwords from sites that do not use a secure connection, or use your channel for illegal activities.
Some models support the new WPA3 standard, and if all your devices (smartphones, laptops, TVs) are new enough (released after 2018-2019), it makes sense to switch exclusively to WPA3, which will provide maximum protection against brute force attacks.
💡
WPA2/WPA3 encryption is the current security standard, and using older protocols makes the network vulnerable to hacking in minutes.
