Modern wireless routers from Xiaomi deservedly occupy a leading position in the budget and middle segment of the network equipment market. miwifi_r4a_g, Also known as Xiaomi Mi Router 4A The Gigabit Edition has been a hit with affordable pricing and dual-band support, but for many users, the initial configuration of the device may seem difficult due to the interface and lack of Russification in standard firmware.
The right router setup is the foundation of a stable operation of the entire home network. If you ignore basic security parameters or make a mistake in choosing the type of connection, the Internet speed can be much lower than the declared provider. In this article, we will discuss in detail the process of connecting, setting up PPPoE, DHCP, static IP, and optimizing 2.4 and 5 GHz wireless networks for maximum coverage.
You don't have to be a network engineer to understand the 192.168.31.1 menu. We'll go all the way from unpacking the device to creating a guest network and setting up IPTV. We'll focus on the nuances of working with Chinese firmware versions and how to translate them, which is often a stumbling block for beginners.
Preparation of equipment and physical connection
Before you start the software configuration, you need to ensure the correct physical connection of all components. Xiaomi Mi Router 4A router is equipped with gigabit WAN and LAN ports, which allows you to transfer data at speeds up to 1000 Mbps. It is important to use a high-quality twisted pair cable category not lower than Cat5e to realize the potential of the device.
Connect the power supply to the router and plug the plug into the socket. Wait until the system indicator flashes yellow or blue, signaling the end of the operating system boot. Then connect the provider's cable to the WAN port, which is usually painted blue or marked accordingly.
For initial setup, you should use a wired connection to your computer or laptop. Connect the device to any of the LAN ports (yellow) using an Ethernet cable, which will provide a stable communication channel without interference typical of the wireless connection at the time of initial configuration.
If you can't use the cable, you can connect over Wi-Fi. Find a name that starts with a name on the list of available networks. Xiaomi_ or MiWiFi_, You can connect to it. You don't have a default password, the network is open. IP-router.
Log in to the web interface and language selection
After a successful physical connection, you need to log into the router control panel. Open any web browser (Chrome, Firefox, Opera) and enter in the address bar IP-192.168.31.1 or the domain name miwifi.com. If the page does not load, check the network card settings for automatic receipt IP-address.
The first screen will greet you with a greeting and a start button, and it's important to pay attention to the status of the system. If the green indicator is on, the router is ready to go. Red or yellow may indicate that there is no Internet or a need to update the firmware.
⚠️ Note: If the interface is entirely in Chinese, this is standard for global versions. To switch to English or Russian (if a patch is installed), look for the globe icon or gear icon in the upper right corner, or use the translator in the browser.
The system will suggest creating an administrator password. Remember this password, as it will be used to log in to settings and manage your Wi-Fi network. Don't use simple combinations like "12345678," as this creates a vulnerability for unauthorized access.
Some firmware versions may require you to log in through your Mi Account, a company security requirement that allows you to remotely manage your router via a mobile app, sign up or log in to an existing account to continue.
Configuring an Internet connection (WAN)
The key step is to set up the type of connection to the provider. The Xiaomi Mi Router 4A router supports the main protocols: Dynamic IP (DHCP), PPPoE, Static IP and PPTP/L2TP. The type of connection is usually specified in the contract with the ISP.
The most common option is Dynamic IP, and in this case, the router automatically receives all the necessary parameters from the provider's hardware, and you just need to select this item from the menu and click "Next." The Internet should appear instantly.
If the provider uses the PPPoE protocol (often found in Rostelecom, Dom.ru, Beeline), you must enter the login and password issued when concluding the contract. Be careful when entering: the system is sensitive to the letter register and the presence of spaces.
For users with static IP-The address will need to be manually entered IP, subnet mask, gateway and DNS-This data is also provided by the provider, and a single digit error will result in no network access.
☑️ Checking the settings WAN
Once you have selected the type of connection, the router will try to establish a connection. Connected status or the green indicator on the home page is a sign of success. If the connection is not established, check the WAN cable and the correctness of the entered data.
Configuration of Wi-Fi wireless network
Xiaomi Mi Router 4A is dual-band, supporting 2.4 GHz and 5 GHz frequencies. 2.4 GHz range provides greater wall coverage and penetration, but has a lower speed. 5 GHz frequency offers high data rate, but has a shorter range.
In wireless network settings, you can set names (SSIDs) and passwords for each band separately, and it is recommended to use complex passwords using different register letters, numbers and special characters to protect against brute force hacking.
There is a smart connection option where the router distributes the devices between frequencies, but for fixed devices that require high speeds (TVs, consoles), it is better to manually connect them to a 5 GHz network.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Maximum speed | up to 300-400 Mbps | up to 867 Mbps |
| Coverage | High. | Average. |
| Wall penetration | Good. | Low. |
| Channel loading | Tall. | Low. |
Broadcast channel choice also affects stability: In densely populated homes, it is better to use automatic channel selection or manually choose the least loaded channel, anaesthetizing the environment using Wi-Fi analyzer applications.

Advanced settings and security
The advanced settings section contains tools for power users, where you can configure Port Forwarding for game servers or video surveillance, which allows external devices to access certain services within your local network.
Parental controls allow you to restrict access to certain sites or set time intervals for the Internet for specific devices, a useful tool for monitoring children's time online.
⚠️ Note: When you turn on UPnP, devices on the network can open ports on their own, which is convenient for gaming and torrenting, but reduces security.
Guests can be activated, creating an isolated Wi-Fi segment that doesn't have access to your personal files and printers on the main network, and can change or set a time limit for guests.
Remember to update your router firmware regularly. The manufacturer releases updates to close security vulnerabilities and improve stability. Updates can be checked under Status or System Settings.
💡
If you use torrent clients on a router or PC, limit the number of simultaneous connections in the settings to avoid putting the Xiaomi 4A router processor on.
Removal and resetting of settings
Connection or speed issues can occur during operation, often with a simple reboot of the device, and if the router has stopped responding to commands or the Internet has gone missing, a complete reset may be required.
To reset, find a hole on the back that says Reset. Press it with a paper clip or needle and hold it for about 5-10 seconds until the indicator blinks. The router returns to factory settings and you have to go through the setup procedure again.
If there are constant communication breaks, check the temperature of the device. Xiaomi Mi Router 4A does not have active cooling, so place it in a well-ventilated place, away from heat sources and direct sunlight.
Speed problems can be caused by an outdated network card driver on your computer or interference from microwave ovens and Bluetooth devices. Try changing your Wi-Fi channel or moving your router to a more central part of your apartment.
💡
Full Reset removes all user settings, including Wi-Fi passwords and provider settings, and only use this feature if other problem-solving methods have failed.
Mobile application Mi Wi-Fi
To manage your router from your smartphone, Xiaomi has developed the Mi Wi-Fi app, which is available for iOS and Android. The app allows you to monitor traffic, manage connected devices and set up a guest network in a couple of clicks.
You can also install plugins through the application that extend the functionality of the router, for example, you can configure the download of files to the connected one. USB-storage or media server for the TV.
The router and the app are particularly useful for remote control, so you can turn off the network to an uninvited guest at any time, or check if the Internet is turned on for children while at work.
