In today’s digital world, a smartphone has long ceased to be just a phone, becoming a universal tool for communication and entertainment. Often situations when you need to urgently connect to the global network from a laptop or tablet, and access to fixed Wi-Fi is not. Owners of Xiaomi, Redmi and POCO devices can easily turn their gadget into a full-fledged router using the built-in functions of the Android operating system with the shell of MIUI.
The process of creating an access point, or Hotspot, on devices of this brand is as simple as possible and does not require the installation of third-party software. However, despite the simplicity, there are many nuances that affect the stability of the connection and data transfer speed. In this article, we will discuss in detail how to set the modem modem modem modem mode, which options to choose for maximum performance, and how to avoid common errors when connecting third-party devices.
Consider not only the standard Wi-Fi distribution method, but also alternatives such as: USB-A modem and Bluetooth panorama that can be useful in specific situations, and understanding how these features work will allow you to stay online at all times, regardless of external circumstances. It is also important to consider the impact of the distribution of traffic on the battery autonomy and temperature of the device.
Preparation of a smartphone and checking mobile traffic
Before you activate the access point, you need to make sure that your device is ready to work in modem modem. The first step is to check if there is an active connection to the network of the cellular operator. Make sure that the upper right corner of the screen displays 4G or 5G icons, as the speed of the transfer depends directly on the quality of the signal received. If the indicator shows EDGE or G, using the smartphone as a router will be inefficient due to low bandwidth.
The second critical aspect is the status of your data plan, and many carriers limit or separately charge the distribution of the Internet to other devices. ⚠️ Warning: Before activating modem modem, be sure to check with your operator the tariff conditions to avoid unexpected charge-offs or blocking of the service (TTL), to determine that traffic is being distributed, so it is recommended to study the forums for your operator in advance for current settings.
Also worth checking is battery power. Access point mode is an energy-intensive process that can quickly drain a smartphone. It is recommended to connect the device to a charger or power bank if you plan a long session. Also, make sure that the phone does not run background processes that consume a huge amount of traffic, such as updating games or downloading movies, so as not to share a channel with the connected devices.

If you plan to use your phone as a router for a long time, remove the protective case for better heat sink, as the Wi-Fi module can get very hot.
Setting up a Wi-Fi hotspot on Xiaomi
The main and most popular way to distribute is to create a wireless Wi-Fi network. First, you need to go to the settings menu of your Xiaomi. Find a section that is usually called “Wi-Fi Access Point” or “Portable Wi-Fi.” The path may vary slightly depending on the version of the MIUI shell or HyperOS, but the logic remains the same. Often this item is hidden inside the Connection and Sharing menu.
Once you log into the access point settings menu, you will need to specify a network name (SSID) and password. Network name can be any, but it is better to avoid special characters that may not display correctly on some devices. Password must be strong, contain at least 8 characters, including letters and numbers, to prevent unauthorized access to your traffic. Using the WPA2-Personal security protocol is standard and provides an adequate level of protection.
In advanced settings, you can choose a frequency range. The default is often 2.4 GHz, which provides longer range but less speed. If your plug-in devices support the 5 GHz standard, it makes sense to switch to it for a more stable connection and faster speed, especially if you are in an apartment building with many neighborhood networks.
☑️ Setting up the access point
Distribution of the Internet through USB-cable
If the wireless connection is unstable or requires maximum speed and minimal latency, the best solution is to use the device. USB-This method also allows you to charge your smartphone at the same time, which solves the problem of fast battery discharge. To implement this method, you will need a quality cable that can transmit data, not just charge the device.
Connect your smartphone to your computer or laptop through USB-The port may be asked to operate on the phone screen. USB, Select Charge or File Transfer, although often the system itself determines whether to activate the modem. Then, on the smartphone, in the same Access Point menu, find the switch «USB-"Modem" and activate it. The computer must automatically determine the new network connection and install the necessary drivers.
The advantage of wired connectivity is that there is no interference and a higher level of security, because access to the network requires a physical connection. USB-The modem will not be able to distribute Internet over Wi-Fi from the phone, because the communication module switches to wired data mode. This is a hardware-level limitation of most mobile chipsets.
⚠️ Attention: When in use USB-Modems on Windows computers may require drivers, which are usually installed automatically, but in rare cases, they will have to be downloaded from the manufacturer's official website.
Using Bluetooth to distribute the network
Bluetooth Tethering is the least popular, but sometimes the only way to share the Internet. The speed of data transfer via Bluetooth protocol is much lower than through Wi-Fi or USB, so this method is only suitable for texting, working with messengers or navigation. For heavy tasks such as streaming videos or downloading files, this method is ineffective.
To set up, you must first pair Xiaomi smartphone with the receiving device (laptop, tablet or other phone) through the standard Bluetooth menu. After successfully pairing and confirming access codes, on the smartphone in the access point menu, activate the option “Bluetooth modem”. On the receiving device in the Bluetooth connection settings, you need to select the option to use network access through this device.
The main advantage of this method is extremely low power consumption compared to Wi-Fi. A smartphone can run in Bluetooth mode for hours without significant loss of charge. However, the latency in such a connection will be high, making it impossible to use online games or video calls.
Advanced settings and optimization of MIUI
MIUI offers a number of additional features for access point management. One of the useful options is to set a traffic limit. You can set a limit of, say, 1 GB, after which the Internet distribution will automatically stop, which will save you from unexpectedly exhausting the data packet if you forget to turn off modem mode.
You can also manage a list of connected devices in the settings. MAC-The addresses of all the gadgets that are currently using your Internet. If you notice an unknown device, you can lock it directly from the interface or change the password of the access point. Regular monitoring of the customer list helps control traffic consumption.
Another important feature is the shutdown timer, which allows you to set up an automatic shutdown of the hotspot if no device is connected to it for a certain time (e.g., 5 or 10 minutes), which prevents the battery from running out of value when you forget to turn off the handout mode after use.
Hidden settings through the engineering menu
For advanced users, you can manually change your Wi-Fi channel. If automatic channel selection leads to unstable work, you can try to capture a particular channel (for example, 1, 6 or 11 for 2.4 GHz) that is less crowded in your area.
Comparison of distribution methods and problem solving
To make it easier for you to choose the right way to distribute the Internet, we have prepared a comparative table of the main characteristics of each method, which will help you quickly navigate depending on your current needs and operating conditions.
| Parameter | Wi-Fi Hotspot | USB-modem | Bluetooth |
|---|---|---|---|
| Transmission speed | High (up to 100+ Mbps) | Maximum (stable) | Low (up to 2-3 Mbps) |
| Energy consumption | High. | Low (charging in) | Very low. |
| Number of devices | Up to 10 (depending on model) | 1 | Up to 7 devices |
| Range of action | Up to 15-20 meters | Cable length | Up to 10 meters. |
Often, users have a problem when devices see the network, but the Internet does not work. First of all, check whether the mobile Internet is working on the smartphone itself by opening any site in the browser. If the sites do not load, the problem is on the operator's side or in the settings of the access point (APN). Try resetting the access point to the factory and create a new one.
Another common problem is frequency incompatibility. If the laptop is old and does not support the 5 GHz standard, and the phone is forced to choose this range, the connection will not take place. In this case, you need to switch to 2.4 GHz. Also make sure that the smartphone does not turn on the power saving mode, which can block the background operation of the Wi-Fi module.
💡
For maximum speed and stability, always choose USB-modem if the laptop is nearby. For mobile devices, the best choice is Wi-Fi 5 GHz.
