Changing the factory access settings is the first step that every owner of new network equipment must take. Standard credentials listed on the case sticker are often made public to a wide range of people, creating a vulnerability in your home network. Attackers can use open access to steal identity or connect to your Internet channel for illegal activities.
The procedure for updating encryption keys on Xiaomi devices does not require deep technical knowledge, but requires attention to detail. Depending on the router model and the firmware version, the management interface may differ slightly, but the logic of actions remains the same for the entire ecosystem of the brand.
Before you start changing settings, make sure your device is connected to the router stably. interrupting the setup process can cause you to lose access to the administrative panel and have to perform a complete reset of the device to factory settings with the Reset button.
You need to get to the router control interface to get started, and you can do this from any device that has a browser, whether it's a smartphone, tablet, or computer, and connect to your router's Wi-Fi network, or use it. LAN-direct-connection.
Open any web browser and enter in the address bar IP-The default for most Xiaomi models is 192.168.31.1 or the domain name miwifi.com. If the address has been changed before, see the current one. IP in the network settings of your computer.
On the welcome screen, the system will ask for an administrator password. The administrator password and the Wi-Fi password are different things, although when you first set them up, users often make them the same for convenience. If you haven't changed the login data to the control panel, try the combination shown at the bottom of the router, or the password you set the first time you turned on.
Once you've logged in, you'll be taken to the main status page, which shows connected devices, Internet speeds and current operating conditions, and we're interested in the wireless security section.
Find a tab or menu item labeled as Wi-Fi or Wi-Fi Settings. In some firmware versions, this section may be hidden inside the General Settings or System Settings menu. The interface may be in English or Chinese, so focus on wireless signal icons.
In the window that opens, you will see a field with the current network name (SSID) and password field, and this is where the access key is edited, and you should choose the type of WPA2-PSK or WPA3 encryption if your hardware supports the latest security standards.
☑️ Checking before changing password
Come up with a strong access key. It should contain at least 8 characters, including capital letters, lowercase letters, and numbers. Avoid using obvious combinations like "12345678" or date of birth. The more complex the password, the harder it is to find it with brute-force.
Once you have entered the new value, scroll down and click Save/Apply. The router will warn you that all wireless devices will be disconnected from the network, which is the normal system response to changing encryption settings.
Your device that you were setting up will also lose your connection, and you'll need to re-locate your Wi-Fi network in the list of available ones and enter an updated password to connect, and if you log in successfully, the Internet should work.
What to do if I forget the administrator password?
Smartphone owners often prefer to manage the network through the official Mi Wi-Fi app (also known as Mi Home), which is convenient because it allows you to control the network remotely from home, if you are attached to an account.
Run the app on your smartphone and make sure you are logged in to your Xiaomi account. Select your router from the device list. If the device doesn't show up, press + and add the router again, following the instructions on the screen.
In the router control menu, look for the Settings section (usually the gear icon) and go to the Wi-Fi settings section. Here, the procedure is similar to the web interface: enter a new network name and password, then confirm the changes. The application automatically reboots the wireless module.
💡
Use the guest network for visitors to avoid giving them the primary password. In the settings of the Xiaomi router, you can turn on guest mode with a separate name and a temporary restriction of access.
Beyond the Wi-Fi password, it is critical to protect the router control panel itself. Many users ignore changing the administrator password, leaving it standard or blank, allowing anyone who connects to Wi-Fi to change network settings or redirect traffic.
To change your administrator password in the web interface, go to System or Status (often indicated by a wrench icon).
Enter your current password and come up with a new one that is different from the Wi-Fi password, which creates a double layer of protection, and once saved, you have to log in again to the control panel using the new data.
💡
Sharing passwords for login to the admin and accessing Wi-Fi significantly improves security, since compromise of one key does not give full control over the device.
When setting up security, there is often confusion between different types of passwords and names, and understanding the difference between them will help avoid errors when connecting gadgets.
Below is a table explaining the main parameters you will change during the security settings of your Xiaomi router.
| Parameter | Description | Wherever used |
|---|---|---|
| SSID | Wireless network name visible in the list of available connections | When searching for Wi-Fi on your phone/laptop |
| Wi-Fi Password | Encryption key for connecting client devices | Introduced at the first connection of the gadget |
| Admin Password | Password to log into router settings (web interface) | At the entrance to 192.168.31.1 |
| Encryption | Data encryption protocol (WPA2/WPA3) | Determine the level of protection of the transmitted data |
Note that changing the type of encryption from WPA2 to WPA3 can cause older devices (such as printers or older smartphones) to stop seeing or connecting to the network, in which case you will need to return to mixed mode or WPA2.
⚠️ Warning: When you change your Wi-Fi password, all your devices (TVs, cameras, phones) will shut down. You will have to reconnect each of them manually, entering a new key.
If you have changed your settings and can’t connect, try removing the network on your device (forget the network) and finding it again. Sometimes DNS cache or old connection profiles interfere with the correct authorization with new parameters.
Also check if the filtering function is enabled. MAC-If it's active, the router will block the connection even with the correct password if it's not active. MAC-The address of the device is not on the whitelist. This option is in the advanced wireless settings.
If you lose access to the router completely and can not remember the administrator password, use a mechanical reset. Press the Reset button on the router on the turned on for 10 seconds before changing the color of the indicator. The device will return to the state "out of the box".
⚠️ Note: Do not use special characters (such as quotes or currency symbols) in your password if you have devices based on older operating systems.
Timely password updates are a basic element of digital hygiene, and changing your access keys regularly, at least every six months, minimizes the risk of unauthorized access to your local network.
