Smartphones are no longer just call devices, becoming fully mobile routers that can provide a stable connection to any equipment. Owners of Xiaomi, Redmi and POCO devices often face the need to quickly access the network from a laptop or desktop computer where there is no built-in Wi-Fi module or Ethernet cable is not connected. The function of the access point in the shell of MIUI is implemented very flexibly, allowing you to choose between a wireless connection and a wired mode, which is especially important for work on trips or when a home provider fails.
However, despite the apparent simplicity, the customization process can have its own nuances, depending on the version of Android and the interface modifications. USB-The cable is often more stable and energy efficient than wireless mode, but requires the correct setup of drivers on the computer. In this article, we will take a detailed look at all the available connection methods, from standard settings to hidden engineering menus that will help you bypass operator restrictions or fix connection errors.
Preparation of a smartphone and checking the tariff plan
Before you start actively setting up the access point, you need to make sure that your mobile Internet is working correctly and has enough speed to transfer data to other devices. Turn off the Wi-Fi on the smartphone itself and try to open a few “heavy” pages or run high-resolution video to check the stability of the cellular signal. If the speed is low, the traffic distribution to the PC can be ineffective, as encryption and routing protocols put additional strain on the phone processor.
An important step is to analyze your mobile carrier plan. Many providers automatically track the TTL (Time To Live) of packets and block the distribution of traffic if they see that it is not used on the smartphone itself. In some cases, operators simply charge an additional fee for using the phone as a modem, so it is recommended to clarify the terms of your tariff in advance to avoid unpleasant surprises with the balance.
⚠️ Warning: Uncontrolled Internet distribution can quickly exhaust your traffic packet. High-quality video and game updates on PC consume gigabytes of data much faster than mobile apps.
Make sure your device is on and 4G/LTE is activated, as 3G speeds will be critically low for full computer performance, and check if the phone has a traffic saving mode that can limit background activity and connection speeds for connected customers.
Method USB-modem: stable wired connection
The most reliable way to provide a computer with access to the network is to use the USB-This method is ideal for situations where maximum speed and minimal latency are required, such as online games or video conferencing, where Wi-Fi instability is unacceptable. To start, connect your smartphone to your PC using high-quality cable, preferably original or certified, as cheap analogues can only support charging without data transfer.
After the physical connection, you need to activate the appropriate mode in the Android settings. → Connection and sharing → USB-The system automatically detects the connection and tries to install the necessary drivers, although in modern versions of Windows 10 and 11 this process often occurs without user intervention.
☑️ Verification USB-connection
If your computer can’t see the network, you may need to manually install ADB drivers or Xiaomi-specific drivers, which can be found on the official support website. Windows Device Manager should have a new device in the Network Adapters section that identifies your phone as a network card.
⚠️ Note: When connecting through USB The phone can get hotter than usual due to simultaneous charging and active data transfer.
One of the main advantages of a wired connection is the absence of radio interference and a higher level of security, since data is transmitted over a physical channel, which is more difficult to intercept remotely. In addition, the smartphone battery does not discharge, but instead charges, which prolongs the battery life in the field conditions.
Setting up a Wi-Fi access point on Xiaomi
The wireless method is most popular due to its versatility and lack of need for additional cables. To distribute Wi-Fi from your phone, lower the notification curtain and find the Access Point icon, or go to Settings → Connection and Sharing → Wi-Fi Access Point. Here you can not only turn on the feature, but also customize network settings in detail for security.
The most important parameter is the choice of the security standard and frequency range. In the access point settings menu, it is recommended to choose the WPA3-Personal or WPA2-Personal encryption protocol to prevent unauthorized access to your network. It is also worth paying attention to the choice of the range: 2.4 GHz provides longer range and compatibility with older devices, while 5 GHz gives a higher speed but has a shorter range.
To change the network name (SSID) and password, click on the appropriate fields in the settings menu.The password should be complex, contain letters and numbers to prevent neighbors or passers-by from picking up the key, who may try to connect to your open network.
💡
Use it. QR-Quick connection code. Xiaomi access point menu has a "Share" feature QR-code, scanning which, the guest will connect without entering a password.
Keep in mind that active Wi-Fi distribution significantly increases power consumption. If you plan to work long hours, it is best to keep your phone connected to the charger, even if the battery does not drain instantly.
Using Bluetooth to distribute the Internet
Although this method is used less often due to the speed of data transfer, it can be a rescue in emergency situations when the data transfer speed is reduced. USB-The cable is forgotten, and the Wi-Fi module on the PC is defective or missing. the connection speed over the Bluetooth channel is limited by the specifications of the protocol and rarely exceeds the specifications of the protocol. 1-2 Mbps, which is enough only for loading pages of text or working with mail, but not enough for streaming video.
To set up, you must first pair the devices: turn on Bluetooth on both devices, find your phone in the list of available on your computer and confirm the pairing code. After successfully creating a pair, in the Bluetooth settings on the PC, you need to select your device and click “Connect via» → «Access point».
On the smartphone side, you also need to activate the appropriate switch. Go to Settings → Connection and Sharing → Bluetooth modem and turn on the function. Without this step, even if you successfully pair, the Internet will not be transmitted.
The main advantage of Bluetooth modem is extremely low power consumption compared to Wi-Fi. The phone can work in this mode for hours, almost without heating, which makes this option suitable for long trips, where every percentage of battery charge is important.
Solving driver and network visibility problems
A common problem when connecting Xiaomi to Windows is the lack of RNDIS drivers that are responsible for the operation of Ethernet devices via USB. If an unknown device with an exclamation mark appears in the Device Manager or the phone is determined only as a media player, you need to manually update the driver. To do this, select “Update driver” → “Research for drivers on this computer” → “Select a driver from the list of available drivers”.
In the list of hardware types, find Network Adapters, and in the list of manufacturers, select Microsoft. USB RNDIS remote NDIS Internet-based Sharing Device: Once this driver is installed, the system must correctly recognize the phone as a network card and assign it to the network card. IP-address.
| Problem. | Possible cause | Method of decision |
|---|---|---|
| PCs don't see the network | RNDIS drivers not installed | Manual installation through Device Manager |
| No Internet access | DNS or APN error | Resetting network settings or re-creating a point |
| Low speed. | 2.4 GHz channel overload | Switch to 5GHz band |
| The phone's running out fast. | Use of the USB-power-cable | |
| Connection error | Blocking by the operator | Changing TTL or using third-party applications |
In some cases, a simple network reset helps. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Note that this action will remove saved passwords from Wi-Fi networks, but often resolves software conflicts.

Bypassing distribution blockages from operator
Many mobile operators are implementing Internet Distribution Detection (Tethering Detection) systems, analyzing the data of the Internet. TTL by default in Android and MIUI This parameter is often 64, and when you connect a PC, it decreases by 1 (becomes 63), which signals the operator that the tariff conditions are violated. TTL system-level.
The easiest way to avoid Root Rights is to use third-party apps from Google Play, such as «TTL Master" or analogues. These utilities allow you to change the system parameter through ADB-commands or special scripts, making traffic from the computer indistinguishable from the traffic of the smartphone itself for the provider.
adb shell su -c"echo 65 > /proc/sys/net/ipv4/ip_default_ttl"This command, executed through a computer with ADB installed and superuser rights on the phone, changes the TTL to 65. When you pass through the phone, the value decreases to 64, and the operator sees the standard package. However, on modern versions of Android, this may require unlocking the bootloader.
⚠️ Note: Changes in system settings may disrupt some network services. TTL will stop working messengers or sites, return the default value.
An alternative method is to use proxy servers or VPN-Tunnels that encrypt all traffic, hiding packet headers from being analyzed by the provider, but this method can significantly reduce connection speeds due to encryption and remoteness of servers.
💡
Changing TTL is the most effective way to bypass locks, but requires caution and an understanding of network protocols.
