Preparation of equipment and physical connection

Before you start the software setup, you need to ensure the correct physical connection of all components of the network. 4C four-piece LAN-port and port WAN-You need to be able to switch cables with care, and you need to set up from your computer an Ethernet cable (patch cord), which is usually included, or any other serviceable cable category. Cat5e higher.

Connect the ISP cable to a blue port, designated WAN. Then take the second end of the Ethernet cable and connect one of the yellow LAN ports on the router to your computer's network card. Make sure the indicators on the ports flash to signal physical contact. The device is powered via a micro-USB connector, so make sure the power supply is plugged into the socket and the router itself is switched on with a button on the back.

⚠️ Warning: Don't try to configure your router exclusively over Wi-Fi at the initial stage unless you're sure of factory settings.The wireless connection may be unstable at the time of reconfiguration, resulting in loss of access to the web interface and the need to reset the device.

• 🔹 IP-address: 192.168.31.100 (or 192.168.1.100)
• 🔹 Subnet mask: 255.255.255.0
• 🔹 Main gateway: 192.168.31.1 (or 192.168.1.1)
• 🔹 Preferred DNS: 8.8.8.8

Once you have set up the settings, open the command line and enter ping 192.168.31.1 (or your gateway). If you see the answers from the node, then the physical and logical connection between the computer and the router is correctly established.

To customize locally without being linked to the cloud, select the option to create a local password. Come up with complex code consisting of letters and numbers, as it will be used to access settings in the future.

It is important to distinguish between the Wi-Fi network password and the router login password. While the system may suggest making them the same for convenience, from a cybersecurity perspective, it is better to use different combinations, which will prevent unauthorized access to network management, even if someone learns the password from the wireless access point.

Basic settings of the Internet and wireless network

Once you've logged in, you'll be taken to the main menu of the web interface, which displays the Internet connection status, if the provider's cable is connected correctly, the router will automatically try to determine the connection type, and in most cases, Dynamic IP (DHCP) is used, and the Internet will start working immediately.

For more complex configurations, such as PPPoE (often used by providers like Rostelecom, Bilain, Dom.ru), you need to go to Settings → Internet. Choose the type of connection and enter the username and password issued by the provider in the contract. Errors in one character will lead to the inability to log in, so check the register of letters carefully.

Next, you set up the wireless module. Go to the Wi-Fi settings section. Here, you should do the following:

• 📶 SSID (Network name: Replace the standard name with any convenient one, avoiding special characters and Cyrillic for maximum compatibility with older devices.
• 🔒 Security: Select the encryption mode WPA2-PSK or WPA3, if supported by customers, avoid using Open mode or WEP.
• 📡 Channel and width: For the 2.4 GHz band (only available in the model) 4C) It is best to set a channel width of 20 MHz for stability or 40 MHz for speed if the ether is not loaded with neighbors.

⚠️ Note: Xiaomi Mi Router model 4C It only works in the 2.4 GHz band. Do not try to find settings for 5 GHz, as this equipment does not physically support this frequency range.

After making all the changes, be sure to click the "Save" or "Apply" button. The router can restart to apply the new Wi-Fi settings. The computer connected by cable will retain the connection, and the wireless devices will need to be reconnected with a new password.

DHCP-So you can set the range of addresses you give, for example, from 192.168.31.100 to 192.168.31.200, and the time you rent an address, and this is useful for creating static references. MAC-address.

Function MAC Filter allows you to create a whitelist or blacklist of devices, you can deny access to the network to specific devices, or, conversely, only allow connection to trusted gadgets. MAC-the address of the network adapter of the device that you need to limit.

Also worth checking out is the System Update section, which is convenient, but in some regions it may be delayed or buggy, and it is recommended to check for a new firmware version manually periodically through the Status → System Status → Upgrade menu.

Recommended sequence of actions during updating:


1. Save the current configuration (Backup).




2. Connect the PC to the router with a cable.




3. Download the firmware file from the official website.
