How to distribute the Internet from Xiaomi phone to laptop through USB-cable: full guide

In situations where Wi-Fi routers are not available and mobile internet is the only window into the digital world, Xiaomi users often resort to the hotspot function. However, standard wireless connection does not always provide the proper stability or speed, especially when downloading large files or during video calls, this is where wired connectivity comes to the rescue, which guarantees minimal delays and no interference from neighboring networks.

Use of the USB-The cable for data transfer between the smartphone and the computer is a time-tested method that is relevant for all Redmi models and the Internet. POCO. This approach not only saves the battery power of the phone, but also allows you to turn your gadget into a full-fledged external modem with high bandwidth.

In this article, we will discuss the configuration process in detail. USB-shell-modem MIUI You will learn about the intricacies of choosing a cable, installing the necessary drivers in Windows and solving the typical problems that owners of Xiaomi equipment face when trying to organize wired traffic sharing.

Advantages of wired connection over Wi-Fi hotspot

The switch to cable offers tangible advantages over traditional Wi-Fi, primarily ping stability, which is critical for gamers and those working with remote servers, and wireless signals are subject to interference, while physical contact provides a secure communication channel.

In addition, when using Wi-Fi access point smartphone is subjected to significant heat stress, which can lead to trottling processor and reduced data transfer speed. wired connection relieves the load from the wireless module Wi-Fi, allowing the system to work in a more gentle mode.

Security is also important: cable data transmission eliminates the risk of interception by attackers within wireless range, especially when dealing with sensitive corporate information in public spaces.

• 🚀 Maximum connection stability without speed jumps.
• 🔋 Simultaneous charging of the device during the distribution of traffic.
• 🔒 High level of protection of transmitted data from external interference.
• 📉 Reducing the load on the smartphone radio module and reducing heating.

It is important to understand that the speed of the Internet will ultimately be limited by your ability to use it. SIM-But by minimizing the loss on the transmission side from phone to PC, you can get the most out of the available channel.

⚠️ Attention: When used actively USB-The modem in the background can update applications or sync cloud services, which quickly exhaust your traffic.

Equipment requirements and cable preparation

For the successful implementation of the plan, you will need not only a Xiaomi smartphone and a computer, but also a high-quality one. USB-Many users make the mistake of using cheap cables designed solely for charging, which have no internal data lines to transmit.

Check the integrity of the connectors on both devices. Dust or contact oxidation can lead to unstable connections when the system detects and loses the modem. It is recommended to use the original cable from the delivery kit or a certified analogue with a label that supports data transfer.

Make sure your computer is properly maintained. USB-It is advisable to connect the smartphone directly to the motherboard (back of the system unit) or use ports. USB 3.0 (blue) for better bandwidth, although the standard 2.0 is sufficient for an internet connection.

If you use a laptop, check if the power supply is turned off. USB-Power saving ports: Sometimes the Windows operating system may limit the current required for external devices to function properly, causing the modem to malfunction.

Setting up USB-modem on Xiaomi smartphone

The process of activating the function on the Android side is quite simple, but has its own characteristics depending on the version of the MIUI shell. The first thing you need to connect the phone to the computer using the prepared cable and wait for the system to determine the device.

After the physical connection, go to the settings menu. The path may be slightly different, but most often it is in the Settings section. → Connection and sharing → USB-In some versions of the firmware, this item can be hidden until the cable is connected.

At the time of switching on the toggle USB-The modem system can request confirmation or alert you about possible traffic consumption. USB or a network connection symbol other than Wi-Fi.

⚠️ Note: If the computer does not see the network after turning on the function, try to switch the mode of operation. USB. To do this, pull the notification curtain down, click on the connection notification. USB and select the "File Transfer" mode, or"MTP", Although the modem is often suitable and the modem "Only Charge", but drivers may not stand up.

In rare cases, newer versions of Android require manually selecting a network type. If the automatic definition does not work, go to the mobile network settings and make sure that the preferred 4G/LTE or 5G network type mode is enabled, as in 3G Only mode, the speed can be critically slow.

Installation of drivers and setting up Windows

Windows 10 and 11 have good built-in support for mobile devices, but Xiaomi sometimes requires manual driver installation to work properly. If an unknown device with a yellow exclamation point appears in the Device Manager, this is a signal to action.

Most often, the system automatically pulls up standard RNDIS (Remote Network Driver Interface Specification) drivers. If this does not happen, you can try updating the driver through Device Manager by selecting "Update Driver" → "Automatic Search".

If you fail, use the MIUI-built debugging mechanism. Enable developer mode by clicking seven times on the build number in the About Phone section, then in the Developer Menu, find the Select USB Configuration option and set the RNDIS (USB Ethernet) value.

The sequence of actions for the developer mode:


1. Settings → About the phone




2. 7 times press "Version MIUI"




3. Settings → Advanced settings → For developers




4. Find "Select the USB configuration"




5.Select RNDIS

Once you change configuration, reconnect the cable. The system must identify a new network device. If that doesn't work, it may be that the system has disabled the Remote Access Connection Manager service, which you need to activate via services.msc.

Comparison of speed and stability of connection

To objectively assess the effectiveness of the method, consider a comparative table of the different ways of distributing the Internet from Xiaomi phone to laptop, the data are averaged and depend on the conditions of reception of the signal of the base station.

As you can see from the table, USB-The connection is winning in almost every way, except for mobility. You're tied to the length of the cable, but you get a connection quality close to wired Ethernet.

The difference is particularly noticeable when working with heavy content: streaming 4K video, downloading game updates or working with cloud databases is much smoother. TCP/IP protocol works more readily with a wired connection, less often initiating the resending of lost packets.

💡

USB-The modem provides the best balance between speed, ping and power consumption, making it the perfect choice for stationary work behind a laptop.

Solving Connection Problems and Errors

While it’s easy to set up, users may face a number of common problems, including one that a computer sees the phone as a charger, not as a modem, in which case switching the USB mode that I mentioned earlier or replacing the cable with a better one can help.

Another common situation is that there is Internet on the phone, the modem icon is on, but the computer has a status "No Internet access." Check your carrier's APN settings. Sometimes you need to prescribe special access point settings for distribution, although for most modern tariffs this is done automatically.

• 📶 Check if the traffic has ended. SIM-map.
• 🔄 Restart both devices – phone and laptop.
• 🛡️ Turn it off. VPN on the phone before switching on the modem.
• ⚙️ Reset your network settings in Xiaomi’s Recovery Menu.

If the problem is with Windows drivers, try removing the device in Task Manager along with the driver, and then reconnect the cable.The system will try to install the driver again, which often eliminates software conflicts.

⚠️ Note: Some carriers block or limit the speed of the Internet distribution to other devices (TTL-If the speed drops sharply after connecting the laptop, perhaps your tariff does not imply unlimited distribution.

Also worth mentioning is the IPv6 issue: In rare cases, Windows prefers IPv6, which is not fully supported by the operator. Try checking the "IP version 6 (TCP/IPv6)" box in the network adapter properties, leaving only the fourth version.

Optimization of work and useful tips

Extend the battery life with frequent use USB-The modem is advised not to keep the phone in a case if it is too warm. Although the load is less than with Wi-Fi, the processor still works more actively than usual.

Use traffic monitoring apps to control data consumption. Android or third-party utilities built in will help set limits and avoid a nasty surprise at the end of the month.

💡

If you use your phone as a modem often, create an inclusion shortcut. USB-modem on the desktop through the application "Shortcuts" in MIUI, Not to go into the menu every time.

Remember to reboot your smartphone periodically. Prolonged modem operation can lead to a buildup of temporary errors in the Android network stack, which is solved by a simple reboot.

When choosing a location for your phone while you're working, give preference to the areas with the best signal reception. Put the gadget closer to the window or on the hill - this will directly affect the speed that your laptop will get.
