How to connect Xiaomi phone to your computer as a USB-modem

In situations where fixed Internet is not available or Wi-Fi signal is too weak, the smartphone becomes the only salvation for access to the network. Owners of Xiaomi and Redmi devices often use the gadget not only for calls, but also as a full-fledged tool for work. USB-Internet cable is the most stable and energy efficient way to provide a computer with access to the global network.

Unlike wireless Wi-Fi hotspots, wired USB connections ensure minimal latency (ping) and no data packet loss, especially for online games, video conferencing or downloading large files, and the smartphone charges from the computer at the same time, so you don’t have to worry about battery drain during a long session.

The process of configuring the MIUI or HyperOS interface is as simple as possible, but it requires attention to detail. You will need a good cable and a basic understanding of how the Android operating system manages network connections. Let's break down all the steps in detail so that you can quickly activate the Internet on your PC.

Conditions and equipment preparation

Before you start setting up, make sure you have a serviceable one. USB-Many cheap cables, which come with portable batteries or cheap gadgets, are designed only for charging and do not have the necessary wires to transmit the signal. If your computer can’t see your phone at all, try replacing the cord with an original or certified phone.

You also need to make sure that your mobile operator plan includes data services and does not exhaust the traffic limit. USB-The modem consumes the same amount of data as when using the browser on the phone itself. Operators can block the distribution of traffic to other devices, so check the terms of your tariff in advance.

• 🔌 Correct. USB-cable (preferably original Xiaomi).
• 📱 Smartphone with active SIM-map and mobile internet enabled.
• 💻 Computer or laptop with serviceable USB-port.
• ⚙️ Installed basic drivers ADB (usually put automatically).

Check if the mobile Internet is on on the device itself. Without an active 4G/LTE connection, you can't distribute, sometimes enabling flight mode and then turning it off to reboot the communication module.

⚠️ Note: Some carriers determine the type of device from which a request is made and can block traffic if they see that the Internet is being handed out on a PC. Use this feature with caution if you have a tariff with limited traffic.

Step-by-step activation instruction USB-modem

The process of turning on the modem in the MIUI shell takes no more than a minute. First connect the phone to the computer using a cable. After the connection, the Android system will default to Charge Only mode. You need to change this setting so that the computer recognizes the network interface.

Open the settings menu and find the Connections and Sharing (or Additional Features in older versions) section. This is where the basic network interface management tools hide. USB-If the device is inactive (gray), the cable is not connected or the computer can't see the device.

After turning on the slider in the upper right corner of the smartphone screen will appear USB icon. on the computer in the tray (near the clock) should appear a notification about the connection of a new network device. Windows will automatically install the necessary drivers, if they have not been downloaded before.

If the driver hasn't been automatically installed, you may not have the basic Android components in the system. In this case, try connecting your phone to USB debugging mode, but it doesn't usually require that to run the modem, just switching the USB mode in the notification curtain to File Transfer, although the modem often works in charging mode.

Set up a network on a Windows computer

Once the function on the phone is successfully enabled, the computer's operating system must determine the new network connection. RNDIS remote NDIS Internet-based Sharing Device: A computer perceives a phone as a normal network card with an external IP-address.

In most cases, the setup is automatic. However, if the Internet is not available, check the settings. IP-Open the control panel. → Network and Internet → Network Control Center. Find an active connection that matches your phone and make sure to be on the protocol. IPv4 It is necessary to automatically receive the address.

Sometimes Windows can give the connection a status of "No Internet access." In this case, try resetting the network settings. Open the command prompt on behalf of the administrator and type in the command netsh winsock reset, then restart the computer, which will clear the cache of network sockets and often solves the problem.

💡

If the driver is not installed automatically, try manually specifying the path to the driver in Device Manager: select "Update driver" → "Find on this computer" → specify the folder where the Android SDK Platform Tools is installed.

Solving common problems and errors

Users often face a situation where the phone is charging but the modem is not turned on.This may be due to port locking. USB into BIOS I'm not sure if you're using a motherboard or not having access rights on Android, and I want you to check if you're not using a data ban on your phone. USB.

Another common problem is conflict. IP-If your computer is already connected to another network (e.g. via Ethernet or Wi-Fi), router conflicts may occur. USB-linkage.

• 🔄 Reboot: Reboot both phone and computer – this solves 80% of driver problems.
• 🔌 Change the port: Connect the cable to another USB-port, preferably USB 2.0, as they work more consistently with modems.
• 🛡️ Antivirus: Temporarily disable firewall or antivirus that can block the new network interface.

If nothing works, try to enable USB debugging mode. Go to Settings → About Phone and 7 times click on the MIUI build number. In the Developer menu, activate USB Debugging. This can help the system correctly identify the device.

⚠️ Warning: Do not remove the abruptly cable during active data transfer.This can damage the phone's file system or freeze the Windows network adapter, requiring a restart.

Impact on battery and data security

Using a smartphone as a modem greatly increases the load on the processor and radio module, but when connected via USB, the phone receives power from the computer. It is important to monitor the temperature of the case: if the device is very hot, it is better to remove the case for better heat sink.

Unlike an open Wi-Fi network, USB-The connection is physically secure, data is not transmitted by air, which prevents the ability to intercept passwords by neighbors, but when connecting the phone to other people's or public computers, be careful: In file transfer mode, an attacker could theoretically access your data.

For maximum security when using other people's PCs, always choose "Charge Only" or"USB-modem" avoiding "file transfer mode (MTP)". In modem modem, your computer sees only the network interface and does not have access to photos, contacts or files on your device.

Comparison USB-modem and Wi-Fi access point

The choice between wired and wireless handouts depends on your goals. USB-The modem provides higher connection stability and lower power consumption, since the phone does not waste resources to create a Wi-Fi field.

Wi-Fi access point is more convenient if you need to connect several devices at the same time (tablet, laptop, smart watch). However, the range is limited, and the phone battery in this mode discharges very quickly, even when connected charging, due to heating.

💡

USB-A modem is a choice for stationary work with a single device, where ping stability and no delays are important, for example, for video calls or online games.

If you're working with big data or you're in important negotiations, always give cable preference. Wireless is good for quick access to mail or instant messengers, but doesn't guarantee the quality (QoS) needed for heavy tasks.
