Connection to the Internet through USB-Xiaomi's smartphone cable is a reliable way to distribute the network when Wi-Fi or mobile hotspot are not available, USB-The modem provides a stable connection without loss of speed, minimal battery consumption and protection from external interference. However, many users face problems: the phone is not defined as a modem, drivers are not installed, or the connection is constantly broken.

In this article, we will discuss all the current ways of activation. USB-modem on Xiaomi devices (including Redmi, Poco and Mi), consider the typical errors and their solutions, and give recommendations for optimizing the connection.

• 🔄 Update. MIUI The latest stable version (especially important for the Redmi Note) 10/11 POCO X3/X4).
• 🔌 Use the original cable – cheap analogues may not support data transfer.
• 🛠️ Check the ports. USB On the computer: try other connectors (especially the ones you use) USB 3.0).
• 📱 Turn off the energy saving for USB in battery settings (can block data transmission).

⚠️ Note: Some Xiaomi models (e.g. Redmi) 9A POCO M3) USB-The modem is disabled by default in regional firmware. If the option is not in the menu, you will need to manually activate via the ADB (let's take it down).

adb devices

(Your device should be displayed. If not, check the drivers.)

adb shell settings put global tether_dun_required 0

adb shell am start -n com.android.settings/.TetherSettings

After execution of commands in settings there will be a hidden option USB-If that doesn't happen, try an alternative command:

adb shell content insert --uri content://settings/system --bind name:s:tether_dun_required --bind value:i:0

⚠️ Attention: On devices with MIUI 14 and may require additional permission WRITE_SECURE_SETTINGS. To obtain it, you need root rights or a patched boot image (for example, through Magisk).

Method 3: Use of third-party applications (without root)

If standard methods don’t work, you can use apps from Google Play that activate the app. USB-modem through the detours:

• 📲 PdaNet+ — Xiaomi supports no root, but requires drivers to be installed on PC.
• 🔗 ClockworkMod Tether – works on most devices, but can brake on weak chips (Helio) G35/G80).
• 🚀 USB Tunnel – optimized for MIUI, The paid version removes the traffic restriction.

Instructions for PdaNet+:

5. Typical errors and their solutions

Even after the right setup USB-The modem can be unstable. Let's look at the most common problems and how to fix them.

If none of the methods worked, check:

• 🔍 Integrity USB-cable - try another wire.
• 📵 Flight mode – it blocks all network functions, including modem.
• 🔋 Battery charge - at a level below 15% MIUI can turn off the modem.

💡

If USB-The modem is unstable on Windows 11, disable Automatic parameterization in network connection properties.

6. Optimization of connection speed and stability

To maximize speed and minimize cliffs, follow these guidelines:

1. Turn off background apps that consume traffic (such as updates or cloud backups).
2. Use USB 3.0 – it provides speeds up to 5 Gbps versus 480 Mbps for USB 2.0.
3. Set traffic priority: On Windows: Control Panel → Network Connections → Properties → QoS. On Android: Turn off automatic app updates in Google Play.
