Xiaomi as a USB modem: a complete guide to setup

Modern Xiaomi smartphones have long ceased to be just devices for calls, turning into powerful multimedia centers capable of performing the functions of a router. When the Wi-Fi router fails or you are on a business trip away from the usual access points, it is your Xiaomi that can be the salvation. USB-The modem allows you to broadcast mobile Internet to your computer, providing a stable and fast connection that often surpasses wireless counterparts in reliability.

Unlike the classic Wi-Fi handout, a wired connection ensures no packet loss and lower latency, which is critical for online gaming or video conferencing. In addition, the use of a cable allows you to simultaneously charge the device, avoiding the rapid discharge of the battery, which is inevitable when the access point is operating wirelessly. USB-Modem on Xiaomi smartphones, what nuances should be considered and how to eliminate typical connection errors.

Using a smartphone as a network adapter is not just a convenience, but also a necessity in situations where wired Ethernet is not available, and the use of a mobile phone is not a necessity. USB-The system is free. MIUI It provides the user with flexible tools to manage network connections, but hidden settings and drivers can raise questions for beginners. We will consider all stages of setting up so that you can at any time turn your gadget into a full-fledged Internet source for a laptop or desktop PC.

Advantages of wired connection via USB

The first and foremost advantage of using a cable is connectivity stability. Wireless networks are affected by interference from microwave ovens, neighboring routers, and even indoor walls. When you connect Xiaomi via USB, you create a direct physical connection that eliminates signal loss and provides the highest possible speed that your carrier maintains, and this is especially true for users working with large amounts of data.

The second important aspect is power consumption: when operating in Wi-Fi hotspot mode, the smartphone heats up and loses charge quickly, because the radio module is running at its limit. USB-The modem is powered by a computer, which allows you to work for hours without recharging. Moreover, Android optimizes network operation when wired, reducing the background load on the processor.

Data security is another argument in favor of cable: Open Wi-Fi networks in cafes or airports carry the risk of interception of traffic. USB-modem, you're creating a personal, secure network that only your computer can access, and it's ideal for working with sensitive information outside the office.

⚠️ Note: When using your smartphone as a modem, monitor traffic consumption. Your computer can automatically start downloading system updates or cloud files, which will quickly exhaust your mobile limit.

Preparation of a smartphone and a computer

Before you start setting up, you need to make sure that your equipment is ready to go. First of all, check whether your Xiaomi mobile data is enabled. Without an active plan or Internet bundle, the modem function will be useless. Also make sure you use quality USB-A cable that can transmit data, not just charge the battery.

On the computer side, the operating system must support network adapters via USB. In modern versions of Windows 10 and 11, as well as in macOS and Linux, the necessary drivers are often installed automatically. However, older versions of Windows may require manual installation of ADB drivers or specific Xiaomi drivers.

It is important to check the status SIM-Make sure it's properly installed and defined by the system. If you use a dual-symbol phone, select the card that has internet in the default settings. Sometimes the system may try to use data from a card that has a limited or expired fare.

💡

Use the original cable from the kit or a certified analogue. Cheap charging cables often don't have internal lines to transmit data, which will make the computer only charge the phone, but not see it as a modem.

Step-by-step activation instruction USB-modem

The process of turning on modem modem on Xiaomi devices is as simplified as possible by developers. First connect the smartphone to the computer using the help of the device. USB-After the connection, the notification may request a choice of mode of operation. USB (only charging, transferring files, etc.), but this is not always necessary for a modem, although selecting the File Transfer mode sometimes helps the system to recognize the device faster.

Next, go to the smartphone settings. The path may vary slightly depending on the version. MIUI, But it usually looks like this: Settings. → Connection and sharing → USB-In some firmware, this item may be immediately in the "Access Point" menu. WLAN". Activate the switch opposite the point USB-modem.

Settings → Connection and Sharing → USB- Modem → On-board

Once you activate this feature, a new network connection icon should appear in the tray of your computer (bottom right on Windows), the system will identify a new network device and try to install drivers, and if it goes well, the network indicator will show access to the Internet.

💡

Function USB-The modem on Xiaomi is activated only when the cable is physically connected to the PC. In the disabled state, the switch in the menu will be inactive (grey).

Set up parameters and fix problems

Sometimes the connection is not smooth and the computer can not see the Internet. In this case, it is worth checking the Device Manager on the PC. If the device is displayed with a yellow exclamation mark or as "Unknown device", the problem lies in the drivers. For Xiaomi, it often helps to install universal drivers or update software through the official utility Mi PC Suite.

Another common problem is carrier blocking, and some plans prohibit Internet distribution (Tethering), and if there is Internet on the phone and the pages on the PC are not loaded, the operator may be blocking the service. TTL-In such cases, more complex manipulation of the change may be required. TTL in roaming settings or use of third-party applications.

Also worth paying attention to the energy saving settings: In MIUI, aggressive battery optimization can turn off the USB port to save energy. Go to the battery settings and make sure that there are no strict restrictions on system or USB-related processes.

Features of working with different versions of MIUI

The MIUI shell interface is constantly updated, and the settings may change. In newer versions, such as MIUI 13 and 14, and in the new HyperOS, the menu has become more logical, but the names of items may differ. For example, in some regional firmwares (Global, EU, China), the path can lead through the "More" section of the access point menu.

Users of Chinese firmware (CN) may find that some menu items will be in Chinese, in which case you should focus on icons or use a screenshot translator, the structure of network settings in Xiaomi remains the same for all regions, only language tags change.

It is important to note that on some models with budget iron, simultaneous work is carried out. GPS, Bluetooth and USB-The modem can put a strain on the antenna module, and if you notice a drop in speed, try turning off Bluetooth while you're running, and that frees up the RF resource for more stable data transmission through the network. USB.

⚠️ Warning: Do not turn off the cable abruptly during active data transfer. Although current systems are resistant to breaks, this can cause the network adapter to freeze in Windows and have to be restarted through Device Manager.

Alternative ways to distribute the Internet

If wired methods don't work for you, Xiaomi has other options, and the classic Wi-Fi hotspot creates a coverage area around the phone that can connect up to 10 devices, which is convenient for tablets or laptops that don't have a wireless connection. USB-Type-A port, but as mentioned, it is a more energy-consuming method.

There's also the ability to distribute the Internet via Bluetooth, which is the fastest way to do this, but it uses the least amount of power, and it's good for emergencies, when you need to send a text message or a light email, and your phone's battery is running out. 1-2 Mbit/s.

💡

For maximum comfort when working with USB-Modem, fix the phone in an upright position, which will improve heat removal from the back and provide better reception of the cellular network signal, since antennas are often located around the perimeter of the housing.

The choice of method depends on your current tasks. USB-The connection is the uncontested leader in stability and ping. Wi-Fi is better for short-term access from several gadgets. Understanding these nuances allows you to effectively use the capabilities of your smartphone in any situation.
