Following the sequence of actions will ensure that your Xiaomi 4C router will work correctly the first time.
Initial preparation and physical connection
Before moving on to software settings, it is necessary to ensure the correct operation of the device at the hardware level. Xiaomi Mi Router 4C The router comes in a minimalist package, including the router itself, a power supply, and a short network cable, which is sufficient for the initial connection to a computer. Make sure the outlet you plan to plug the device into is working and provides a stable voltage, as power surges can damage sensitive electronics.
On the rear panel of the device are four LAN ports and one WAN port, which are highlighted in blue or marked with a separate label. The blue port is where you should connect the cable from your internet service provider (or from your modem, if you're using a modem-router setup). Connect a computer or laptop to any of the four black LAN ports using an Ethernet cable for initial setup, although modern smartphones also allow you to do this wirelessly.
⚠️ Caution: Do not connect the ISP cable to the LAN ports (black) or the computer cable to the WAN port (blue). Reversing these connections will result in the internet not working, even if all settings are correct.
After connecting the cables, connect the power supply to the connector Power Press the power button, if available, or simply wait until the indicators light up. The system should boot within 30-60 seconds, indicated by the system indicator glowing steadily or flashing.

Login to the web settings interface
Once the physical connection is established, you need to access the router's control panel. To do this, open any modern browser on the connected computer or smartphone. In the address bar, enter the device's default IP address, which is the default for the product. Xiaomi makes up 192.168.31.1You can also use a letter address. miwifi.com, which is often written on a sticker under the bottom of the device.
When you first log in, the system will automatically detect that the router is new and launch a quick setup wizard. The interface may be in English or Chinese, but modern browsers offer a built-in translator to help you navigate. If the page doesn't load, check your computer's network card settings: it should automatically obtain an IP address via the protocol. DHCP.
In some cases, especially when using older firmware versions, the system may require linking to a mobile application. Mi Home or Mi WiFiWhile not always required, using the app significantly simplifies future device management, allowing you to control the network remotely. To access the app via a browser, simply agree to the user agreement and click Continue.
Setting up connection type and internet
The most important configuration step is choosing the correct connection type to your provider's network. Xiaomi Mi WiFi 4C Supports the main protocols: dynamic IP (DHCP), static IP, PPPoE, L2TP, and PPTP. In most cases, unless you previously had a router or your ISP has provided special instructions, the device will automatically detect the connection type. Dynamic IP (Automatically), and the Internet will work immediately.
If your provider requires authentication (PPPoE protocol), which is common with providers like Rostelecom or Dom.ru, you will need to enter the login and password specified in your contract. This information is critically important, and even a single character error will result in loss of access to the global network. If you use a static IP address, which is rarely assigned by your provider, you will need to manually enter the IP address, subnet mask, gateway, and DNS servers.
| Connection type | Required data | Where to get |
|---|---|---|
| Dynamic IP (DHCP) | Not required | Automatically from the provider |
| PPPoE | Login, Password | Agreement with the provider |
| Static IP | IP, Mask, Gateway, DNS | Provider technical support |
| L2TP/PPTP | Login, Password, Server | Agreement with the provider |
After selecting the connection type, the router will attempt to establish a connection to the provider's server. A successful connection is usually indicated by the internet indicator changing to green or blue, and the corresponding status appearing in the web interface. If the connection fails, double-check the information you entered or contact your service provider's technical support.
What should I do if my ISP binds my internet connection to my MAC address?
Some providers remember the MAC address of the first device connected to the cable. If you've changed your router, your internet connection may not work. In this case, find the "MAC Address Cloning" section in the Xiaomi 4C settings and copy the MAC address of the old router or computer that previously had internet access.
Wi-Fi wireless network configuration
Configuring your wireless network is key to ensuring a comfortable internet experience on mobile devices. In the Wi-Fi settings section, you can change the network name (SSID) to any convenient name to easily identify your access point among neighboring ones. It is recommended to use Latin letters and numbers, avoiding special characters, as some older devices may not correctly display names with Cyrillic characters or emoji.
Particular attention should be paid to the choice of password and encryption type. Xiaomi Mi Router 4C Supports both WPA2-PSK and WPA3 security standards, with the former being the most compatible with all devices. The password must be complex and contain at least 8 characters, including upper- and lower-case letters and numbers, to protect your network from unauthorized access and "neighbor" traffic.
- 📡 Dual-band: The 4C only operates on the 2.4GHz band, which provides good coverage but can be susceptible to interference from microwaves and Bluetooth devices.
- 🔒 Safety: Never leave your network open (without a password), as this makes your personal data vulnerable to interception.
- 📶 Signal strength: In the settings, you can select the transmitter power mode (Eco, Standard, Penetrating), which affects the coverage area.
This section also includes a guest network feature, which allows you to create a separate hotspot with limited access to your local network. This is a useful option if you have guests over and want to provide them with internet access but don't want to share your main password or open up access to your network resources, such as printers or NAS storage.
⚠️ Note: If you change your Wi-Fi settings (name or password), all connected devices will lose connection to the router. You will need to reconnect to the network on each device using the new settings.
Changing the administrator password and updating the software
The administrator password is the key to managing the router itself, and it's different from the Wi-Fi password. By default, during initial setup, the system will prompt you to create a new password to log in to the web interface or link the device to an account. XiaomiIt is highly recommended to set a unique, complex password, as access to the router's settings gives you complete control over your home network.
Regular firmware updates (firmware) is the key to the stable operation and security of your device. The manufacturer periodically releases updates that fix bugs, patch vulnerabilities, and add new features. You can check for a new version in the "Status" or "System Settings" section by selecting "Manual Update."
The update process takes several minutes, during which the router will reboot, temporarily disconnecting your internet connection. Do not unplug the router's power cable during the update, as this may cause irreversible damage to the software and render the device inoperable. If automatic updates are not available, you can download the firmware file from the official website and upload it via the web.
