The modern smartphone has long ceased to be just a means of communication, becoming a full-fledged center for managing digital tasks. Owners of Xiaomi, Redmi and POCO devices often face the need to use mobile traffic on a laptop or desktop computer when wired Internet is not available. Internet distribution (or access point creation) is a regular feature of the MIUI shell, which works stably, but has its own nuances depending on the chosen connection method. In this article, we will discuss in detail all available methods of data transmission, their advantages and configuration features.
Choosing the right method depends on your goals: whether you need the highest speed to download heavy files or just check your mail on the go. USB-The modem will provide the most stable connection without losing battery power, while Wi-Fi hotspot will allow you to connect multiple devices without wires. Understanding the differences between these protocols will help you effectively manage your smartphone’s traffic and power consumption. Below we will take a detailed look at the algorithms for each option.
Preparing a smartphone for the distribution of the Internet
Before you start setting up, you need to make sure that your smartphone is ready to work in modem mode. First of all, check whether the mobile Internet is activated and whether there are funds or an active tariff package on the balance. The MIUI shell can block the distribution of traffic if there are not enough funds in the account or if the carrier restricts the use of the phone as a router. Also make sure that the operating system version is current, since there may be errors in the communication module in old builds.
An important step is to check the settings of the access point name (APN). Often, providers automatically set the correct settings, but in some cases manual editing is required. Go to the SIM card settings menu and make sure the correct operator profile is selected. USB-Prepare a high-quality cable capable of transmitting data, not only charging the device.
- 📱 Make sure that mobile data is on and the network signal is stable (minimum) 2-3 division).
- 🔋 Check the battery level – for Wi-Fi distribution, it is recommended to have more than 30% charge.
- 📡 Turn off Traffic Savings mode if it is activated in connection settings.
- 🔒 Remove the screen lock or set up automatic unlock if you need a connection confirmation.
Don't ignore security settings before you start a handout. By default, the system suggests setting a password, and it's not recommended to change this rule at your discretion. An open network can become an entry point for attackers who will access your data or start spending your traffic. WPA2 PSK encryption protocol is the security standard for mobile access points and provides reliable connection protection.
Method 1: Distribution of the Internet through USB-cable
Use of the USB-Cables are the most reliable way to turn a Xiaomi smartphone into an external modem for your computer, a method that provides minimal latency (ping) and high data transfer speeds, which is critical for online games or video conferencing. In addition, when wired, the phone is charged at the same time, which avoids the rapid battery discharge characteristic of working in the Wi-Fi router mode.
To activate the function, you need to connect your smartphone to your PC using a cable. Once connected, Android must identify a new device. If the computer is not responding, try switching mode. USB in the notification curtain from “Charge only” to “File transfer” or «USB-In the phone settings, the path to function usually looks like this: Settings → Connection and sharing → USB-Activate the switch, and the system will install the necessary network interfaces.
☑️ Verification USB-connection
⚠️ Warning: Windows may take several minutes to automatically install drivers when first connected.If a device is defined as an "Unknown Device," try using the original cable or other device. USB-port.
It is important to note that when connecting to USB A smartphone can only work with one computer at a time, and some antivirus programs on a PC can block the creation of a new network connection, perceiving it as potentially dangerous, in which case you should add the device to the firewall exceptions. The connection speed in this mode is limited only by the cable bandwidth and the standard. USB (2.0 or 3.0, and operator network speed.
Method 2: Creating a Wi-Fi hotspot
Wireless Internet is the most popular scenario for using a smartphone as a router, a method that allows you to connect multiple devices to the network at once: a laptop, a tablet, and even another phone. To set up a access point on MIUI, go to Settings → Wi-Fi Access Point. Here you can specify the network name (SSID) and password. The system automatically offers a secure encryption option that is compatible with all modern gadgets.
In advanced hotspot settings, you can change the frequency range. 2.4 GHz is the default, which provides better signal penetration, but can be subject to interference from other devices. Switching to 5 GHz will achieve significantly higher data rate, but the signal range will be smaller, and not all older laptops will be able to see such a network. The choice depends on your priorities: range or speed.
- 📶 The 2.4 GHz range is suitable for long-distance operation and is compatible with older devices.
- 🚀 5GHz range provides high speed, ideal for streaming and downloading files.
- 🔋 Using Wi-Fi access point significantly increases the energy consumption of the smartphone.
- 🔐 It is recommended to use complex passwords (minimum 8 characters) to protect against hacking.
The MIUI shell provides a handy Portable Access Point feature that allows you to quickly turn on and off the Dispense mode through the notification curtain. You can also set up automatic hotspot shutdown if your devices are not connected to it for a certain time (for example, 10 minutes), a useful battery-saving option that prevents the Wi-Fi module from running idle.
Method 3: Distribution via Bluetooth (Bluetooth PAN)
Although this method is used less often due to speed, it can be a salvation in situations where USB-cable is unavailable and the Wi-Fi module is faulty or busy.Bluetooth technology PAN (The Personal Area Network allows you to create a network between two devices. Data transfer speed here is limited by the capabilities of the Bluetooth protocol (usually up to the end of the current period). 2-3 Mbps), which is enough for messengers, but not enough for watching videos.
To set up, you first need to pair a Xiaomi smartphone with a computer. Go to the Bluetooth settings on both devices, find each other and confirm the pairing code. After successful pairing on the phone, you need to activate the Bluetooth modem switch in the access point menu. On the computer, you should find the connected Bluetooth device in the network settings and select the “Connect through” option → “Access point”.
Why is Bluetooth Modem Slow?
The main advantage of Bluetooth is that it uses very low power compared to Wi-Fi. A smartphone can run for hours without significant charge loss. However, remember that the range is limited to a few meters, and the devices must be in close proximity to each other. Connectivity stability is also inferior to wired counterparts and can be interrupted if there are physical obstacles.
Configure the access point parameters in MIUI
The MIUI shell offers advanced access point management capabilities that are often hidden from the average user. In the hotspot settings menu, you can not only change your password, but also limit the number of devices you connect, set a traffic limit or run time, which is especially useful if you share the Internet with colleagues or friends and want to control your megabytes.
One of the key features is the ability to hide the network name (SSID). If you activate this optic, your access point will not appear in the list of available networks on other devices. To connect, you will have to manually enter the network name on the client device. This increases security, making your hotspot invisible to random passers-by with Wi-Fi network scanners.
| Setup parameter | Description of function | Recommended value |
|---|---|---|
| Frequency range | Choice between 2.4 GHz and 5 GHz | 5 GHz (for speed) |
| Max. Connections. | Limit of simultaneous devices | 1-3 devices |
| Wi-Fi timeout | Automation in the absence of customers | 10 minutes. |
| AP isolation | Prohibition of data exchange between customers | Included. |
And you should also pay attention to the "AP isolation" feature. If it's enabled, the devices connected to your smartphone won't see each other on the LAN. This is useful in public places, but it can get in the way if you're trying to transfer a file from a laptop to a tablet over a local network. For home use, this option can be turned off for convenience.
Solutions and Connection Errors
Despite Xiaomi’s stability, users may experience situations where the Internet is not being distributed or is intermittent, and one of the common problems is the “failed to connect” error on the computer side, most often due to an incorrect password or conflict. IP-Try to forget the network on the PC and reconnect by entering the password carefully, according to the register of characters.
Another common situation is that the computer sees the network but writes "No Internet access." This may indicate a problem with the settings. DNS Or the mobile Internet itself, check if the sites are opening on the smartphone itself. If so, try changing the type of access point settings on the phone. APN manually DNS-servers (e.g., 8.8.8.8 from Google) in mobile network settings.
⚠️ Note: If you are connected to USB computer can't see the modem, check the drivers installed. Some models may require driver installation ADB or specific drivers MediaTek/Qualcomm, though 10/11 They are usually automatically installed.
In some cases, carriers block traffic by determining the TTL (Time To Live) of packets. If the Internet is on the phone and the PC is not working, perhaps your tariff does not include the distribution option. The solution may require changing the value of TTL in the Android system (root rights are required) or connecting a paid service from the operator. Also try to reboot the smartphone - this often solves temporary failures of network modules.
💡
If the speed is USB Low, try to switch the port on your computer. Connect the cable directly to the motherboard (back of the PC), rather than the front panel of the case or USB-hub.
The impact of Internet distribution on the battery and system
Modem mode puts a high load on the processor and radio module of the smartphone, which leads to intense heating and rapid battery discharge. This is especially true when using Wi-Fi access points on 4G/5G networks, where the communication module is at its limit. Prolonged operation in this mode can lead to battery degradation and even trottling (decreased performance) due to overheating.
To minimize the negative impact, it is recommended to remove the protective cover during the distribution to improve the heat sink. USB-modem, the phone will charge, but the charging speed can be lower than the discharge speed under load, especially if the power supply is weak.Ideally, use the original charger and cable that supports fast charging, even if the modem mode itself does not require high currents.
- 🌡️ Control the temperature of the body - with strong heat, it is better to interrupt the distribution.
- 🔌 With long-term work, USB Use a high-quality low-resistance cable.
- 📉 Close background apps on your smartphone to reduce processor load.
- 💡 Turn down the brightness of the screen or turn off the display during the handout.
The Android core and MIUI shell have security mechanisms that can force the access point to shut down if the battery is overheated or discharged. This is normal behavior designed to keep the device running. Don't try to circumvent these restrictions with third-party applications, as this can damage the hardware components of the smartphone.
💡
USB-Connection is the only way to distribute that allows you to simultaneously work and charge your phone without the risk of rapid wear and tear of the battery.
