In today’s world, mobile internet has become a critical resource, and it often happens that a desktop computer or laptop requires immediate access to the global network, and a wired provider is unavailable or faulty. Xiaomi smartphones equipped with a MIUI shell or the new HyperOS offer powerful tools to create their own access point, turning a device into a full-fledged router. This process, known as modem modem or Hotspot, allows you to stream 4G/5G mobile Internet to other gadgets at high speed.
However, despite the apparent simplicity, users often face nuances: the computer does not see the network, the connection is constantly interrupted or the data rate does not meet expectations. The difference between the frequencies of 2.4 GHz and 5 GHz, WPA3 security settings and the features of the Android system energy saving can significantly affect the stability of the connection. Understanding these technical details will allow you to avoid typical errors and configure the Internet distribution as efficiently as possible.
In this guide, we will take a closer look at the activation algorithm of the access point on Xiaomi devices, consider advanced SSID concealment and connected customer management settings. You will learn how to choose the optimal frequency range for specific tasks, whether it is streaming video or transferring large files, and will also address security issues so that your communication channel remains protected from unauthorized access by unauthorized persons.
Activation of the access point in the interface MIUI and HyperOS
The process of enabling modem modem on Xiaomi smartphones is standardized, but has its own features depending on the version of the operating system. To quickly start the function, just lower the “curtain” of notifications from top to bottom and find the icon “Access Point” (or “Hotspot”). If the icon does not appear on the first screen of widgets, click on the pencil or edit button to add it to the active list. This is the fastest way, but it does not give access to the delicate settings.
For a deeper configuration, you need to go to the system menu. Open Settings, find the Access Point and modem section (in some versions it may be simply called Connections and Sharing). Here you will see the Wi-Fi Access Point switch. This is where key settings like network name (SSID) and password are available. Changing this data by default increases security and makes it easier to identify your network among neighbor signals.
Importantly, in the HyperOS shell, the interface may look a little different, with larger fonts and a changed logic for grouping items. If you can't find the right partition right away, search by settings by typing in "Access Point" or "Modem" and the system will redirect you to the right menu subsection, which is especially convenient on devices with a lot of installed applications.
☑️ Checking before handout launch
After activation of the function, the corresponding indicator will appear in the upper right screen, usually in the form of two staples or an antenna icon. Attention: the active access point significantly increases the battery consumption and heating of the device body. It is recommended to keep the phone on charge or in a cool place during prolonged use.
Frequency range choice: 2.4 GHz vs. 5 GHz
One of the most important settings that is often ignored is the choice of frequency range for broadcasting.In the settings menu of the access point Xiaomi has a “Range of frequencies” where you can choose between 2.4 GHz and 5.0 GHz. Understanding the difference between them is critical to ensure a stable connection with the computer. 2.4 GHz standard has a longer range and better penetration through walls, but it is more loaded with neighboring routers and household appliances, which can reduce speed.
The 5GHz range provides significantly higher data rates and is less prone to interference, but has a shorter range and is less likely to pass through obstacles. If your computer is in the same room with your smartphone and you need to transfer a lot of data or play online games, choosing 5GHz will be the best solution. Old network adapters on computers may not support this standard, so if you have problems with network detection, you should switch to 2.4GHz.
Some Xiaomi models with the latest communication standards have a “No Limits” option or automatic selection, where the system itself determines the best channel. However, for a fixed PC connection to your phone, manual setting often gives a more predictable result. If you use a laptop with modern Wi-Fi 6 network cards, be sure to try 5 GHz mode for maximum performance.
⚠️ Note: When switching the frequency range, the active access point may temporarily shut down. All connected devices will need to reconnect as the technical parameters of the network will change.
Security setting and SSID hiding
Security of data is the number one priority when using public networks or even a personal access point in crowded places. Xiaomi hotspot settings recommend using WPA2-Personal encryption protocol or, if devices support, WPA3-Personal. These standards provide reliable encryption of traffic, protecting your passwords and personal correspondence from being intercepted by attackers.
One of the advanced features available in the security menu is Hide Device, which when activated, your smartphone stops broadcasting the network name (SSID) to the air. To connect, your computer will need to know the exact network name and manually enter it through the Connect to a Hidden Network menu, which creates an additional layer of protection, making your access point invisible to random scans.
The password must be complex, containing different register letters, numbers and special characters. Avoid using simple combinations like “12345678” or date of birth. The password setting menu in MIUI has a “Show password” button, which allows you to visually check the entered characters before saving settings, avoiding errors when entering from the PC keyboard.
What does the SSID coverup do?
Regular password change is also good practice, especially if you suspect that access may have been used by outsiders, and you can always see a list of connected devices on the access point menu, which allows you to quickly identify “uninvited guests” and block their access.
Computer Connection and Customer Management
Once the access point on Xiaomi is activated and configured, the process of connecting on the computer side is no different from connecting to a regular router. On a PC, you need to open a list of available Wi-Fi networks, find your smartphone name and click “Connect”. The system will request the password you set earlier. After successful authentication in the Windows tray or in the macOS menu, the connected network icon will appear.
The connected customers are managed directly from the phone, and the access point menu shows the number of active devices. MAC-The blacklist allows you to block specific devices even if they know the password, and it's especially useful in crowded places where passwords are theoretically possible.
To keep the connection running on your computer, it is recommended that you set up your network profile as “Private” (in Windows), which will allow the device to be visible to other trusted devices on the network, but hide it from public networks. If the connection is established but the Internet is not working, try on your computer to perform a DNS reset command or simply reconnect the network adapter.

The maximum number of connected devices directly affects the Internet speed for each client and the temperature of the smartphone.
Solving common problems and errors
Despite the well-functioning Android system, users may face situations when the computer does not see the network or can not get a computer. IP-The common cause is conflict. IP-It's a simple way to turn off and turn on the flight mode on your smartphone, which reboots the radio module, and it's also worth checking if the mobile traffic restriction in the access point settings is worth it.
If the computer sees the network, but the connection is constantly reset, the problem may be in the power saving settings. The MIUI system aggressively optimizes the background processes. You need to go to the battery settings, find the Access Point application or the Wi-Fi system process, and set the No Limits mode, which will prevent the system from turning off the communication module to save energy.
Another common problem is the “failed to connect” error or endless receipt. IP-In this case, you should try to forget the network and delete its profile, and then reconnect. On the phone, you can try changing the broadcast channel (if there is such an advanced setting) or switching the frequency range from 5 GHz to 2.4 GHz and back to provoke a reconfiguration of the network interface.
⚠️ Note: If a warning appears when connecting that the network does not provide a secure connection, it is normal for a local access point unless you use additional access points. VPN-The key is that you have an encryption icon.
Optimization of energy saving and extension of work
Wi-Fi distribution is one of the most energy-intensive processes for a smartphone. Active transmission of the radio module, constant communication with the base station of the mobile operator and the computing load lead to rapid discharge and heating. To minimize the consequences, it is recommended to reduce the brightness of the phone screen to a minimum or turn off the display completely, as it is an additional source of heat.
Xiaomi's hotspot settings include a "Time Out hotspot" feature. Set a value like 5 or 10 minutes. This ensures that if you forget to turn off the handout after you've finished your PC, the phone will automatically turn off the Wi-Fi module, saving battery power, especially when the phone is used as a modem on trips.
💡
Use the original charger and high-power cable during Wi-Fi distribution, which will offset the power consumption and prevent battery degradation due to micro-discharge cycles.
It also costs (disable) intangible background apps on the phone itself. The fewer tasks a smartphone processor performs in parallel with the Internet, the less it heats up, and closing heavy games or the navigator in the background will help maintain connection stability and temperature of the device.
Use of the USB-modem
If the wireless connection is unstable or requires maximum speed and minimum latency (ping), it is worth considering the option of connecting via a wireless connection. USB-cable, mode USB-Xiaomi modem allows you to transmit an Internet connection over a wire while charging the phone, which eliminates signal loss through the air and reduces battery load, since the power comes from the computer.
To activate this mode, connect your smartphone to your PC with a cable, go to the Access Point and modem menu and turn on the switch «USB-The computer will automatically detect the new network device, and the advantage is that there is no radio wave emission near the user and no neighbors can intercept the signal.
But USB-Connectivity has its limitations: you are "tied" to a computer with a cable length, and at the same time you will not be able to distribute the Internet to other wireless devices from your phone (in most standard configurations). USB It depends on your priorities: mobility and multiconnection versus stability and speed.
