Smartphones are no longer just callers, becoming full-fledged digital space management centers where the Internet distribution function plays a key role. Owners of Xiaomi, Redmi and Poco devices often face the need to quickly provide access to the network to a laptop or tablet using mobile traffic. Standard activation procedure seems simple, but the MIUI shell or its new version of HyperOS hides many subtleties, ignoring which can lead to inability to connect or quickly discharge the battery.
In this article, we will not only take a closer look at the basic steps to start a modem, but also delve into the hidden settings that allow you to optimize network operation for specific tasks. You will learn how to properly adjust the frequency range for maximum speed or signal range, and how to hide your network from prying eyes. Understanding these nuances will allow you to use your smartphone as a full-fledged router without losing communication quality and with minimal power consumption.
Before we get into the technical details, it’s worth noting that the menu interface may vary slightly depending on the version of the Android operating system and regional firmware. However, the logic of the operation remains the same for the entire ecosystem, and knowing the principles will allow you to easily navigate even in updated menus. We will look at universal paths and specific commands that are guaranteed to lead to the desired result.
Basic activation through the control panel
The fastest way to start modem modem modem is to use the top notification curtain, but many users miss the option of fine-tuning right in this menu. You just swipe top-down twice to reveal the full list of shortcuts, and find an icon called "Access Point" or "Hotspot." Clicking on the icon itself instantly activates the function, while a prolonged tap (or click on the arrow next to it) will open the settings menu where you can change the password and the network name.
If you don't have a standard icon in the curtain, you can add it through the Quick Access panel editing menu, which will make it much easier to use. This method is ideal for situations where the Internet is needed "here and now", and there is no time to dig into the deep menus of the system. However, to work constantly or adjust specific parameters, you still need to go to the main settings of the device through the Settings application.
It is important to understand that activation through the curtain often uses the latest saved options, which may not be optimal for the current situation. For example, if you previously set a password with complex characters or selected a 5 GHz range that the old device does not see, you still have to go to the full menu. So basic activation is only the first step that the correct configuration should follow.
Setting up the access point in the MIUI and HyperOS menu
For deep customization, go to Settings → Connection and Sharing → Wi-Fi Access Point. This is where all the levers of control over your personal hotspot are concentrated. Unlike stock Android, Xiaomi’s shell offers advanced functionality, including managing a white list of devices and setting a shutdown timer.
The first thing you need to do is to set a secure network name (SSID) and password. It is recommended to use a mixed register of letters and numbers to prevent the possibility of collecting the key by neighbors or bystanders. In the "Access Point Name" field, it is better not to use personal data, such as surname or apartment number, for digital hygiene and security purposes.
☑️ Network security setting
Special attention should be paid to the “Range of Frequency” parameter. By default, the system can choose automatic mode, but for maximum compatibility with all gadgets (especially older laptops or IoT devices), it is better to explicitly specify 2.4 GHz. If the priority is the speed of transferring large files and all customers support the new standard, choose 5 GHz.
⚠️ Attention: When choosing a 5GHz band, the range of the signal is significantly reduced, and the ability to pass through walls is reduced. If you plan to work in another room, you better switch to 2.4GHz.
Extended settings: SSID hiding and limits
The Xiaomi hotspot settings menu has a feature that is useful for privacy-minded people: By activating the Hide Device option, you will make your network invisible to general scanning, and you can only connect to it manually by entering the exact network name (SSID) and password on the client device.
This feature is useful in crowded areas where attackers can use packet sniffers to analyze open network traffic, but it is worth remembering that a “hidden” network is not a guarantee of complete anonymity, since when connected, the device still broadcasts requests.
How to connect to a hidden network?
You can also set a traffic limit or shutdown timer in this section, and the Timer feature will automatically turn off the access point if no one is connected to it for a specified time (e.g. 10 minutes), a critical setting to prevent battery drain if you forget to turn off modem mode after you've finished working.
Compatibility issues and frequency selection
One of the most common problems is when a laptop or tablet simply “can’t see” the network created by a smartphone, which is 90% due to incompatibility of frequency bands. Old network adapters are physically unable to operate in the 5 GHz band, which is becoming the standard for today’s flagship Xiaomi.
To solve this problem, you need to force the access point to 2.4 GHz mode. This range provides lower speed, but has better penetration and compatibility with devices released more than 5-7 years ago.
Below is a table to help you choose the optimal range depending on your tasks and equipment:
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Transmission speed | Up to 150-300 Mbps | Up to 800+ Mbps |
| Signal range | High (up to 50 m) | Medium (up to 20 m) |
| Pathability of walls | Good. | Bad. |
| Compatibility | Nearly 100% of devices | Only modern gadgets |
| Stability | Maybe it's noisy. | High, less interference. |
If the problem persists after switching the frequency, try changing the channel in the router settings (if the distribution is from it) or rebooting the network module of the smartphone, turning on and off the air mode.
Distribution of Internet via USB and Bluetooth
Wi-Fi is not always the best way to transmit the Internet.If you want maximum connection stability and minimal latency (ping), consider a wired connection through the Internet. USB-This method also allows you to charge your smartphone at the same time, which is not possible with an active Wi-Fi access point.
For activation USB-modem connect the phone to the computer with a cable, go to Settings → Connect and share and turn on the switch «USB-The system will automatically install the drivers, and the computer will perceive the connection as a wired Ethernet network.
💡
Use the original cable for USB-Cheap charging cables often don’t have data lines, which means the computer won’t see the phone despite charging indications.
A Bluetooth modem is an archaic, but sometimes the only option for very old devices or specific hardware, and the transmission speed is extremely low (no more than 2-3 Mbps), but the power consumption is minimal, and this feature is turned on in the same menu as other types of access.
Battery optimization and safety
The access point mode is one of the most energy-intensive processes in a smartphone. The radio module runs at high power, the processor constantly processes network packets, and the screen, if it is turned on, finishes the rest of the charge. To Xiaomi smartphone does not run out in an hour of work, follow the optimization recommendations.
First, reduce the brightness of the screen or turn it off after connecting clients. Second, close the background applications that may consume traffic or CPU resources. In the battery menu, you can activate the power saving mode, but make sure that it does not limit the operation of network services.
⚠️ Warning: During active Wi-Fi distribution, the phone may become noticeably hot. Do not cover the device with a pillow or blanket to prevent overheating and possible battery shutdown or damage.
From a security perspective, never leave a default password access point or worse, no password.Attacker connecting to your network could theoretically try to intercept unencrypted traffic or access your device's shared folders if they are open.
💡
The most effective way to save battery when running an access point is to turn off the smartphone screen and use it. USB-Connecting instead of Wi-Fi where possible.
Frequent questions and troubleshooting
Even if all instructions are followed, specific errors characteristic of firmware may occur. MIUI. Users often ask why the internet on a connected device doesn't work even though the Wi-Fi icon is on, usually by checking for mobile traffic and working properly. SIM-map.
Sometimes the system blocks the distribution because of carrier restrictions, and some plans prohibit the use of the phone as a modem, and changing the TTL (Time To Live) setting will help, but this requires more knowledge and perhaps root rights, which is beyond the standard instruction.
If nothing works, try resetting your network settings, which will delete stored Wi-Fi passwords and Bluetooth settings, but often resolves software conflicts of communication modules.
