How to distribute the Internet from Xiaomi phone to your computer via USB: full instruction

Xiaomi’s modern smartphones allow mobile internet not only to be used on the device itself, but also to be distributed to other gadgets — including computers. One of the most stable and energy-efficient ways to do this is by connecting through a mobile phone. USB-Unlike Wi-Fi, this method does not consume the battery of the phone, provides a higher data rate and works even in low signal conditions.

However, many users face difficulties in setting up USB-modem: the system does not recognize the connection, drivers do not install automatically, or the speed is lower than expected. MIUI, work-related USB-We will give step-by-step instructions for all current versions of Xiaomi, including Android models. 12/13/14.

You'll learn how to activate modem modem properly, what Windows or Linux settings you'll need to change, and what to do if your computer doesn't see the network.

• 📱 Go to Settings. → The phone. → Updating the system.
• 🔄 Click on “Check Updates” and install the available packages.
• 📲 After the update, restart the device.

Also pay attention to the energy saving settings. MIUI aggressively optimises background processes, which can interrupt data transmission through USB. To avoid this:

1. Open Settings → Battery and Performance.
2. Select Battery Consumption Management for applications.
3. Find the settings in the list (or USB-modem, if such a point exists) and set a mode for it without restrictions.

💡

If you have a Xiaomi Redmi Note 10 Pro or a newer model, in the developer settings (Settings) → The phone. → Version. MIUI — Tap 7 times) activate the debugging option USB. This will help to avoid problems with device recognition on the PC.

2. Connecting the phone to the computer and choosing the mode USB

When the phone is ready, connect it to the computer using the original USB-The use of cheap cables often leads to unstable connection or complete lack of data transmission. USB.

You must choose to transfer data (or MTP), And then on the drop-down menu — USB-On some Xiaomi models, for example, POCO X3 Pro) this paragraph may be referred to USB-internet USB-Tethering. If there is no such option, follow the following steps:

Please contact the notification "Charging through" USB"|Select "Data transmission" (MTP)|Check for a point "USB-modem|If there is no item, go to Settings → Access Point and modem-->

If you're optional USB-The modem is not on the menu, this may be due to the:

• 📵 Lack of active SIM-maps or mobile data.
• 🔒 Operator restrictions (some tariffs block tethering).
• 🛠️ Outdated firmware or custom recavery (for example, TWRP).
• 🔧 Active mode Only charging in the developer settings.

On Windows computers 10/11 After selecting the modem modem, the system must automatically install the Remote driver. NDIS. If this does not happen, check Device Manager (Network Adapters section). If there is an exclamation mark next to the Xiaomi device, you will need to manually install drivers.

3. Set up a computer to work with USB-modem

Once a phone is successfully connected, the computer must determine a new network connection, which is usually automatic, but sometimes additional setup is required — especially on Windows 7 or Linux distributions.

3. Press Additional and manually specify DNS (For example, 8.8.8.8 from Google).

4. Solving common problems

Even with the right setup, Xiaomi users often encounter common mistakes, and let’s look at the most common ones and how to fix them.

Particularly noteworthy is the problem of tethering blocking by operators, where some mobile operators (such as Tele2 or Iota) restrict Internet distribution at unlimited rates, to circumvent this restriction:

• 📲 Install PNet or ClockworkMod Tether on your phone (root rights required).
• 🔧 Change. TTL-meaning ADB: adb shell settings put global tether_dun_required 0
• 🌐 Use it. VPN on a phone (such as WireGuard) to mask tethering traffic.

💡

5. Optimization of connection speed and stability

By default. USB-Xiaomi modem may not work at full speed. MTU (Maximum Transmission Unit and prioritization of traffic. Here's how to improve productivity:

To start, check your current connection speed with Speedtest. If the results are significantly lower than expected (for example, instead of 100 Mbps, you get 10 Mbps), follow the following steps:

1. On Windows, open the command line on behalf of the administrator and type: netsh interface ipv4 Show subinterfaces Remember the current value MTU Xiaomi connection (usually 1500).
2. Change. MTU on 1472 (Best for mobile networks: Netsh interface ipv4 set subinterface "ID_SUPPLEMENTS" MTU=1472 store=Persistently ID_Please enter the number from the previous team.
3. Reconnect. USB-modem and check the speed again.

Additional optimization methods:

• 🔌 Use it. USB 3.0 port (usually blue) – this will increase bandwidth.
