How to distribute the Internet from Xiaomi phone to your computer via USB: the complete guide

Modern smartphones Xiaomi and Redmi have powerful functionality, which often allows you to replace a full-fledged mobile router. USB-A modem is not just a way to access the network when Wi-Fi is not available, but also a solution for situations requiring maximum connection stability. USB Ensures less ping and no radio interference, which is critical for online gaming or video conferencing.

Unlike wireless transfer, which quickly lands the battery and heats the case, cable connection provides simultaneous charging of the device, which is especially true for owners of models with a smaller battery or long-term operation in access point mode. In this article, we will discuss in detail how to activate modem modem on MIUI and HyperOS smartphones, and also solve typical driver problems in the Windows environment.

Advantages of Wireless Connection over Wi-Fi Access Point

The switch to wired mode is justified primarily by the requirements for channel stability. Wi-Fi radio is affected by a variety of factors, from microwave ovens to neighboring routers operating at the same frequency. Cable connection eliminates the loss of data packets due to interference, providing predictable speeds.

In addition, USB-themed (as the modem mode is technically called) saves battery power. When working through Wi-Fi, the smartphone functions as a full-fledged transmitter, which causes the processor and communication module to heat up. When wired, the phone receives power from the computer, and the Wi-Fi module can be turned off programmatically if it is not used to receive the signal.

⚠️ Warning: With prolonged use of modem modem, the smartphone may get hot.Do not cover the device with a cloth and ensure air flow to the back, especially if you are simultaneously charging it from a powerful power supply.

Data security is also important: cable transmission makes it impossible to intercept signals from the air, which is important when dealing with sensitive corporate information in public places. USB provides a direct connection between two devices without the involvement of intermediate nodes.

Preparation of equipment and software

Before you start setting up, you need to make sure that the physical connection is working. Successfully activating the modem modem on Xiaomi will require a high-quality cable that can transmit data, not just charge the device. Cheap “charging only” cables will not allow the computer to see the phone as a network device.

Basic drivers must be installed on the Windows side of the computer. Usually, the system automatically finds the software it needs when it first connects, but in rare cases, it may be necessary to manually install ADB drivers or Android SDK components. Check for operating system updates, as they often contain patches for network protocols.

It’s also worth checking your mobile carrier’s plan in advance, some providers block or limit the speed of Internet distribution, while others may charge an additional fee to use your phone as a router, and make sure you have a tethering-enabled package.

However, if the automatic setup didn't work, you can check the adapter settings. press Win + R, type in ncpa.cpl and press Enter. In the window that opens, find a connection that is usually called "Ethernet" with a number or smartphone icon. IPv4 It costs automatic receipt IP-address.

In some cases, especially on corporate computers with tight security policies, administrators may block the installation of new network drivers. If you see a device with an exclamation mark in Device Manager, you may need administrator rights to install the driver. RNDIS (Remote Network Driver Interface Specification).

Problem Solving: Drivers and Connection Errors

The most common problem when trying to distribute the Internet is that the computer does not see the phone or sees it only as a drive, in which case you need to go to Device Manager (right-click on Start and select the appropriate option), find the section "Network adapters" or "Other devices." If there is an unknown device with a yellow triangle, you need to update the drivers.

Try right-clicking on the device and select "Update driver" → "Automatic Search. If that doesn't work, download Google's universal driver. USB Driver or drivers specifically for Xiaomi from the official website of the developers. Also helps to switch debugging mode on the site. USB.

Close background apps that are heavily consuming traffic, such as cloud photo syncs or streaming services, to free up a channel for the main device, and make sure that the phone does not have a traffic saving mode that can artificially lower the connection speed for the PC.

To extend the battery life and ports, it is recommended to use a cable of sufficient length so that the phone is not in a strained state.The constant vibration from notifications or calls can shatter the USB connector on the phone or computer when used actively.
