The modern smartphone has long ceased to be just a means of communication, becoming a universal tool for work and entertainment, which often acts as a mobile router. Owners of Xiaomi, Redmi and Poco devices may face the need to distribute the Internet to a laptop or tablet when stationary Wi-Fi is not available or is unstable. The function of the Wi-Fi hotspot in the shell of MIUI and HyperOS is implemented in a flexible manner, allowing not only to broadcast the signal, but also to fine-tune security and power consumption parameters.
Turning on the modem modem is a process that takes seconds, but knowing the nuances of the settings will help you ensure a stable connection and protect your data from unauthorized access. In this article, we will discuss all the stages of activation in detail, look at hidden settings of frequency ranges and answer frequent questions of users, learn how to manage connected devices and optimize the operation of your smartphone in the distribution mode.
Quick activation through the notification curtain
The easiest and fastest way to run the Internet distribution on Xiaomi devices is to use the Quick Access Panel, which is enough to unlock the screen and swipe down from the top edge of the display to open the notification curtain. In the second row of icons, there is usually a widget called Access Point or Modem Modem, which is activated with a single touch.
If you don't find the right switch on the visible part of the screen, click on the edit icon (usually a pencil or three dots in the corner) and drag the modem icon to the active area. Once turned on, the indicator in the status bar will change, signaling the beginning of the broadcast of the Wi-Fi signal, which is ideal for situations when the Internet is urgently needed and there is no time to delve into the settings menu.
⚠️ Note: When activated through the curtain, the default default default password is used. For security, it is recommended to immediately check the settings of the network name and access key in the full menu.
Keep in mind that fast activation does not allow you to select a frequency range or adjust the traffic limit. This is the basic method that uses standard WPA2-Personal security protocols. If a third party device with a saved password tries to connect to your network, it will gain access automatically, so changing the access key regularly remains an important precaution.
Detailed setting of the access point in the system menu
For a deep configuration of network settings, you need to go to the system settings menu. On modern versions of the MIUI 14 or HyperOS shell, the path is as follows: open Settings, select Connection and Sharing (or just Additional Features on older versions), and find the Wi-Fi Access Point. This is where all the necessary tools for professional settings are hidden.
In this section, you can change the network name (SSID) to make it unique and easily recognizable among many neighboring signals, and you can also set a password where the system specifies the complexity requirements of the security key, and you should use a combination of letters of different register and numbers at least 8 characters long to protect against brute-force attacks.
☑️ Checking security settings
The network name concealment feature deserves special attention. If you activate the Hide Device option, your smartphone will stop broadcasting SSID on air. To connect, other users will have to manually enter the network name in their gadget's Wi-Fi settings, which greatly increases the level of privacy, since random passers-by will not see your access point in the list of available connections.

Frequency range choice: 2.4 GHz vs. 5 GHz
One of the key settings that affect connection speed and stability is the choice of frequency range. Xiaomi access point menus often offer a choice between 2.4 GHz and 5 GHz. Understanding the difference between the two is critical to the proper operation of the modem in different conditions.
The 2.4 GHz range is more versatile and compatible, it provides better signal penetration through walls and obstacles, and is supported by the vast majority of older and budget devices. However, this range is often overloaded with signals from neighboring routers, microwave ovens and Bluetooth gadgets, which can lead to a drop in speed and increased ping.
Technical details of ranges
In turn, the 5GHz band offers significantly higher data rates and is virtually free from interference in apartment buildings. It is an ideal choice for watching 4K video, online games or downloading large files to a connected laptop. However, the range of such a signal is smaller, and it requires line of sight or minimal obstacles between the phone and the client device.
⚠️ Attention: When switching to 5 GHz old devices (released before) 2013-2014 You may not see your hotspot. If your laptop doesn't find the network, try to go back to the Internet. 2.4 GHz.
Managing Connected Devices and Limits
The control over those who use your traffic is through the customer management menu. Xiaomi interface displays a list of all currently connected devices with their MAC-This allows you to quickly identify uninvited guests who may have picked up a password.
The system allows you to set strict limits on the number of connected gadgets. Even if the password is known to ten people, the smartphone will only allow a specified number of devices (usually up to 10), locking a particular device is made in one click: just click on the client name in the list and select the option to Lock or Disable.
- 📱 Identification: The device name is often displayed automatically, making it easier to find your laptop or tablet in the listing.
- 🚫 Blacklist: Locked devices will not be able to connect even knowing the correct password until the lock is removed.
- 📊 Statistics: You can see how much traffic each customer has spent since the last reset of the statistics.
It is important to monitor the connection list regularly, especially if you are using a traffic-restricted tariff.Some apps on connected devices can automatically run a system update or cloud storage sync, which will quickly exhaust your mobile package.
Optimizing energy consumption and working in the background
Modem mode is one of the most energy-intensive processes for a smartphone. The constant operation of the radio module for transmission leads to rapid battery discharge and heating of the case. The MIUI system has built-in protection mechanisms that can interrupt the access point to save energy.
To avoid a sudden shutdown, you need to set up a self-disconnect timer, which turns off the access point if no one connects to it for a predetermined time (e.g. 10 minutes), which is useful if you forgot to turn off the modem after use, but can interfere if you need a permanent connection.
💡
For long-term operation in modem modem, it is recommended to connect the smartphone to the charger and remove the protective case for better heat removal, since the heating can reach 40-45 degrees.
Also worth checking is the battery settings for system services. In the Battery and Performance section, make sure that the access point service does not have strict background activity restrictions. Sometimes aggressive Xiaomi optimization can "kill" the handout process if the smartphone screen is turned off for a long time.
⚠️ Warning: Extended access point operation in high ambient temperatures can lead to battery degradation.Try not to cover your phone with a blanket or pillow while you're running.
Solving Common Connection Problems
Despite the stability of the Android shell on Xiaomi, users may experience situations where devices see the network but can not connect, or the connection is there, but the Internet does not work, most often the problem lies in the incompatibility of encryption protocols or DNS error.
If your laptop says "Can't connect to this network," try changing the security type from WPA3 (if it's on default on new models) to a more compatible WPA2-Personal. Also helps resetting the access point settings to factory values through the Reset settings menu at the bottom of the configuration screen.
- 🔄 Reboot: Banal shutdown and turn on mobile Internet often solves the problem of lack of access to the network.
- 📡 Channel change: Some firmwares have manual Wi-Fi channel installation; channel change can remove interference.
- 📝 Verification APN: Make sure that the access point is correctly spelled out in the mobile network settings (APN) your operator.
In rare cases, the problem may be on the side of the carrier, which blocks the distribution of traffic (tethering) on certain tariff plans. If all settings are correct, but the Internet does not work, it is worth contacting your mobile operator support for more details of the tariff conditions.
💡
In 90% of cases, the connection problem is solved by changing the frequency range (from 5 to 2.4 GHz) or changing the type of encryption to WPA2.
