The modern smartphone has long since ceased to be a mere means of communication, becoming a full-fledged pocket router that can provide access to the global network to any device nearby. Situations when you urgently need to send a work document, check mail or complete a project on a large screen, and there is no fixed Wi-Fi at hand, arise for every Xiaomi user. Fortunately, the MIUI operating system or its more recent version HyperOS provide flexible and simple tools for organizing such a connection.
Using mobile traffic to power a laptop is not only convenient, but often safer than connecting to open public networks at cafes or airports: you have complete control over the flow of data, know who has access to your channel, and can turn off transmissions at any time. In this article, we will discuss in detail three main methods of connection: USB-cable, via Wi-Fi and Bluetooth, and also consider the nuances of the settings that will help to avoid common errors.
Before you start setting up, make sure your plan includes the option of using your smartphone as a modem, as some carriers block or charge this option separately. Also check the balance and availability of packet traffic so that an unexpected Internet shutdown does not interrupt the important download or video call process at the most inopportune time.
Preparation of the smartphone and checking the settings of the mobile network
The foundation of a stable connection is the correct configuration of the access point in the smartphone itself. Before you try to make friends with your laptop and phone, you need to make sure that mobile Internet works correctly and quickly. Open the notification curtain and activate the data transfer, then try to open any page in the browser. If sites load slowly, you may need to move to the best reception zone or switch between 4G and 5G standards.
An important step is to check the settings of the access point APN, which come automatically from the operator, but sometimes require manual adjustment. Go to the Settings menu, select the section SIM-maps and mobile networks, then click on your operator name and find the access point (APN). Here you should select an active profile corresponding to your tariff; if the Internet is not working, reset your settings. APN factory-level.
⚠️ Warning: Before actively distributing the Internet, make sure that the phone does not include traffic saving mode in the background for system processes, otherwise the laptop can see the network, but not receive data.
Also worth paying attention to is the firmware version of your Redmi or Poco device. Older versions of MIUI may have encountered speed-limiting bugs that were patched in later security updates. Regular system updates ensure not only the stability of the communication modules, but also protection against vulnerabilities in data transmission.
For users who plan to use the phone as a modem often, it is recommended to set a traffic limit or a warning about its consumption, which will help to avoid unpleasant surprises at the end of the billing period, when the operator can significantly reduce speed or write off additional funds for exceeding the package.
Method 1: Distributing the Internet through USB-cable (USB-modem)
The most stable and energy efficient way to connect a laptop to the network is to use the USB-This method is ideal for stationary work at the desk, because it not only provides high data transfer speeds, but also charges the smartphone battery, preventing it from quickly discharging. To start, you will need a serviceable cable, preferably original, coming with the device, or a high-quality analogue with data transmission support.
Connect your phone to your laptop through USB-By default, the device can go into charging only mode, so you need to manually activate the modem function. Go to Settings, go to Connect and Sharing (or Additional Features in older versions) and find the item USB-Modem, switch the slider to active position.
☑️ Verification USB-connection
Once the function is activated, Windows or macOS automatically recognizes the new network connection, and the computer will perceive the phone as a wired Ethernet connection, which usually means lower ping and lower packet loss compared to wireless methods, which is especially important for online games or video conferencing, where channel stability is critical.
If the connection did not happen automatically, it is possible that the computer does not have the necessary drivers. In most cases, Windows 10 and 11 download them themselves through the update center, but older versions of the OS or specific Xiaomi models may require the installation of ADB drivers or proprietary software Mi PC Suite.
💡
Use USB 3.0 ports (usually blue) on your laptop for maximum channel bandwidth, especially if your tariff allows speeds above 100 Mbps.
It is worth noting that when using USB-In the modem, some operators can determine the type of device and block the distribution if the tariff prohibits it. USB-The modem often masks the fact of the distribution more effectively than the Wi-Fi access point, since the traffic looks like a regular Internet surfing from a mobile device.
Method 2: Creating a Wi-Fi wireless access point
The wireless method is the most popular because of its versatility and no wires required. To turn your Xiaomi into a router, open the notification curtain and find the Access Point icon. If it's not in the quick menu, go to Settings → Connection and Sharing → Wi-Fi Access Point.
The first step in setting up is to configure the network security configuration. Click on your access point name or the Settings button to change the settings. Create a strong password using a combination of letters and numbers, and select the WPA2 PSK or WPA3 encryption standard if all your devices support the new protocol, which will protect your channel from unauthorized access by unauthorized persons.
The important parameter is frequency range. In the access point settings menu, you can choose between 2.4 GHz and 5 GHz. The 2.4 GHz range provides more coverage and better penetration through walls, but has less speed and is more noisy. The 5 GHz range offers high speeds, ideal for streaming video, but has a smaller range.
⚠️ Attention: Active use of the Wi-Fi hotspot significantly accelerates battery discharge and can cause heating of the smartphone case.
Xiaomi devices also have a “Whitelist” feature, or a restriction on connected devices, which you can manually specify which gadgets are allowed to connect to your network by blocking all other login attempts, an additional security measure that ensures that even if a password is leaked, outsiders will not be able to use your traffic.
Once the hotspot is turned on, the laptop needs to open a list of available Wi-Fi networks, find your phone name (often called a model by default, such as the Redmi Note 10), and enter a previously set password.
Method 3: Connect via Bluetooth (to save energy)
Although this method is less commonly used due to the relatively low data rate, it can be a lifeline in situations where you need to keep your phone battery as long as possible or when you need to keep it on the phone. USB-Bluetooth modem consumes significantly less power than Wi-Fi module, which allows the phone to run in the distribution mode for hours.
The setup process requires pairing devices. Turn on Bluetooth on both devices: on your phone through a curtain or settings, on your laptop through system settings. On your computer, search for devices, find your Xiaomi in the list and click "Plug in." On the phone screen, you'll see a request to confirm the pairing with the code — make sure the codes match, and confirm the action.
Once paired successfully, activate modem mode. On the phone in the Connect and Sharing menu, turn on the Bluetooth modem. On your computer, this step may differ: on Windows 10/11, go to Settings → Devices → Devices → Devices and Printers (or Bluetooth and other devices), find your phone, right-click, and select Connect via → Access Point.
Bluetooth modem connection speeds typically don't exceed 1-2 Mbps, which is enough for messaging, emailing, or navigation, but is completely unsuitable for watching high-resolution video or downloading large files. However, as an emergency option, this technology has proven to be great.
Comparison of methods of connection and selection of the optimal option
The choice of the particular method of distribution depends on your current tasks and environmental conditions. Each of the methods examined has its own strengths and weaknesses, which must be considered to achieve the best result. Below is a comparative table that helps you to quickly navigate.
| Parameter | USB-modem | Wi-Fi access point | Bluetooth modem |
|---|---|---|---|
| Speed. | High (up to 1 Gbps) | Medium/High (up to 300 Mbps) | Low (up to 2 Mbps) |
| Stability | Maximum | Depends on the interference. | Medium |
| Battery consumption | Charging the phone | High-pitched | Minimum |
| Number of devices | 1 (usually) | 10. | 1 |
If you are in an office or at home and need to work several hours in a row, it is definitely worth choosing. USB-This ensures that the laptop has a stable Internet connection and the phone does not run out at a critical moment, and the wired connection eliminates the risk of interception by intruders nearby.
When you're on the road, in a cafe, or meeting with colleagues, when you need to show a presentation quickly or share files, Wi-Fi is indispensable. The ability to connect multiple devices at the same time makes this method the leader in versatility. However, always monitor your work time so you don't end up with a dead phone.

Problem Solving and Speed Optimization
Even with the right setup, users can experience problems such as slow speeds or intermittent connection breaks. One common cause is overheating of the smartphone. When the data is being transmitted, the processor and radio module heat up, and the system can artificially reduce performance to protect the components.
Another problem may be choosing an overloaded Wi-Fi channel. If you use the 2.4 GHz band in an apartment building, the signal can be “clogged” by neighbor routers. In the settings of the Xiaomi access point, there is often an option to automatically select the channel, but you can try manually setting the channel 1, 6 or 11, checking their load with special analyzer applications.
⚠️ Note: If the laptop sees the network, but writes "Without Internet access", try on the phone to switch the mobile Internet to "Only" mode. 4G" Preferred network type, sometimes switching automatically between 3G/4G causes modem malfunction.
It's also worth checking the firewall and antivirus settings on your laptop. Sometimes security software blocks a new network connection, classifying it as public and dangerous. Try temporarily disabling the firewall or changing the network type to "Private" in Windows network connection settings.
For those who have unlimited internet, it is important to know that operators often use TTL (Time To Live) technology to detect the distribution. When you connect a laptop, the TTL value changes, and the operator blocks access. You can change TTL through special applications or root rights, but this requires advanced knowledge and may violate the terms of the contract with the operator.
