The modern rhythm of life dictates its rules, and it often happens that a fixed router is not available and a stable connection is urgent. Owners of Xiaomi, Redmi and Poco devices can easily turn their smartphone into a full-fledged router. This solution allows you to quickly connect a tablet, laptop or other gadget to the global network using mobile traffic.
The configuration process in the MIUI or HyperOS shell is as simple as possible and takes just a few seconds. However, there are nuances that affect data transfer speed and security level, and understanding these features will help avoid connection problems and excessive battery consumption.
In this article, we will take a closer look at all the available ways to organize a wireless network, compare their performance and look at common errors, and learn how to set priority frequencies, set strong protection and optimize power consumption when operating in modem mode.
Basic ways of organizing access points
Xiaomi smartphones offer three main options for transferring the Internet connection to other devices. Each method has its own technical features, advantages and speed limits. The choice of the specific method depends on the capabilities of the receiving device and your current tasks.
The most popular and convenient option is to create a Wi-Fi hotspot. This method requires no wires and allows you to connect several gadgets at once. The signal is transmitted over a radio channel, which provides a high speed comparable to a conventional home router, but increases the load on the battery.
For tablets without Wi-Fi or to save phone charge, a wired connection via USB is ideal. In this case, the smartphone acts as an external modem, transmitting data over the cable, which provides stable ping and no radio interference, which is critical for online games or video calls.
⚠️ Attention: When in use USB-modem make sure the cable supports data transfer, not just charging.Cheap "charging-only" cables won't allow you to establish a connection.
The third option is Bluetooth, which is the least energy-intensive, but also the slowest way, which is suitable for sending small amounts of text or working with mail, but is not suitable for watching videos or downloading heavy files, and the speed is rarely higher than 1-2 Mbps.
Setting up Wi-Fi access point in MIUI and HyperOS
To activate the router mode, you need to go to system settings. The path may vary slightly depending on the version of the shell, but the logic remains the same. Open the Settings menu and find the Wi-Fi Access Point section, which is often hidden in the Connection and Sharing submenu.
In the window that opens, you need to set a network name (SSID) and password. By default, the system offers a random set of characters, but it is better to set a clear name and a complex security key, which will prevent unauthorized access to your traffic.
The frequency range is particularly important. Current models offer a choice between 2.4 GHz and 5 GHz. The first option offers greater range and compatibility with older devices. The second range offers significantly higher speeds but a smaller coverage range.
☑️ Setting up the security of the access point
After switching on the Wi-Fi Access Point torque, the smartphone will start broadcasting the signal. On the tablet, you need to find the network you created in the list of available connections and enter the previously installed password. A successful connection is confirmed by the appearance of a Wi-Fi icon in the status bar.
Organization of wired connection via USB
Cable use is the choice of professionals who value stability over mobility. First, connect your smartphone to your tablet (or computer) with a quality USB Type-C or Micro-USB cable. The system will automatically identify a new device and suggest use cases.
Unlike Wi-Fi, you don't have to enter passwords, but you can see a request for debugging permission or use on your phone screen. USB-modem. Agree to the request to activate the data transfer. In some cases, you need to activate the debugging mode on the data transfer. USB developer menu.
The advantage of this method is that it can charge your smartphone at the same time, and when you're actively distributing Wi-Fi, the battery drains very quickly, and the cable provides a constant supply of energy, which allows you to work for days without interruption, which is especially important when traveling or without outlets.
⚠️ Note: If the tablet can’t see the Internet, try switching mode USB in the notification menu from “Charging” to “File Transfer” or «USB-modem».
It's worth noting that when you connect to a computer, the system can automatically install drivers, and on Android tablets, this process usually happens unnoticed by the user, and the main thing is to make sure that the mobile Internet on the phone itself is active and works correctly.
Advanced settings and network optimization
MIUI and HyperOS shells provide tools to fine-tune the distribution, and you can find the "Setting up the access point" item in the access point menu, which hides important parameters that affect the performance and security of your connection.
One of the key features is setting a traffic limit, so you can set a maximum amount of data, and then the distribution will automatically shut down, and that will save you from the unexpected cost of using a limited gigabyte tariff.
Hidden Network is also available, and if you activate this mode, your access point name will not appear on the list of available networks on other devices, and you will need to manually enter your SSID and password to connect, which increases privacy.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Frequency range | 5 GHz (for speed) | High speed, smaller radius |
| Encryption | WPA2-Personal | Maximum data protection |
| Time out | 10 minutes. | Automatic shutdown when simple |
| Max. Devices. | 1-3 | Reducing the load on the processor |
Don't forget about timeouts. If you set the access point to automatically shut down when there are no connected customers, you can save a lot of battery power. The smartphone will stop wasting resources on signal emission when it is not needed.
How to hide the access point completely?
Solving Typical Connection Problems
Despite the ease of customization, users may experience situations where the tablet sees the network but doesn't connect, or the connection is there and the pages aren't loading, most often the problem lies in the wrong frequency range or outdated network settings.
If the tablet cannot receive IP-Address, try changing your standard Wi-Fi channel on your smartphone. In dense buildings, the channels can be overloaded by neighbouring routers. Switching the access point menu to another channel often solves the problem of unstable connections.
Another common reason is mobile carrier blocking, and some plans prohibit the use of the phone as a modem or require a separate payment for this service, in which case even if the connection is successful, the Internet will not work.
⚠️ Note: Operators can determine the distribution of the Internet by value TTL. Changing this option requires root rights and is not guaranteed on all Xiaomi models.
It is also worth checking the date and time settings, and if the time is lost on a smartphone or tablet, security certificate errors may occur, which blocks access to the device. HTTPS-Synchronizing time over the network usually eliminates this error instantly.
The impact of Internet distribution on the battery and system
Modem mode is one of the most energy-intensive processes in a smartphone, and the active transmission of data over a Wi-Fi radio channel and the simultaneous operation of the 4G/5G module lead to rapid heating of the case and intense battery discharge, which in hot weather can provoke the trottling of the processor.
To minimize harm, it is recommended to remove the protective case during a long distribution to improve heat sink. USB-Connecting or reducing screen brightness and closing background applications.
Long-term access point operation also causes accelerated battery wear, and continuous heating and cooling cycles have a negative impact on lithium polymer battery chemistry, so don't keep your phone in router mode 24/7 unnecessarily.
💡
Use the “Energy Saving” mode on your smartphone while you’re sharing the internet, which will limit the background activity of other apps and extend battery life.
Newer versions of HyperOS have smart cooling algorithms that can limit the speed of the dispensing during critical heating, a normal defense system response aimed at preserving hardware components of the device.
💡
The safest and fastest way to distribute is through USB-cable, as it eliminates radio interference and provides charging of the phone.
