Modern smartphones have long ceased to be just devices for calls, turning into full-fledged control centers for the digital space, including the function mobile routerXiaomi device owners often need to quickly connect their laptop or tablet to the internet when they're out of range of a fixed-line network. The unique MIUI interface, and now HyperOS, offer advanced hotspot configuration options that are often hidden from the average user in standard menus.
The process of activating internet tethering on devices of this brand has its own nuances, different from stock Android or iOS. This applies not only to the visual interface, but also to the logic of the power-saving system, which can aggressively limit background processes. Understanding how to do it correctly configure network settings will allow you to avoid connection interruptions and save battery power when using your device as a modem for a long time.
In this guide, we'll walk you through every setup step, from basic activation to advanced frequency manipulation and network hiding. You'll learn why your laptop sometimes doesn't detect a network and how to set the correct range. 2.4 GHz or 5 GHz And what hidden settings can dramatically impact connection stability. Proper setup will turn your smartphone into a reliable internet source for the entire team or family.
Basic hotspot activation via settings
The easiest and most obvious way to enable tethering is through the system's default settings menu. First, unlock the screen and find the app. Settings, which usually looks like a gear. In the list of categories, you should find the section Connection and sharing, although on some firmware versions it may be called simply "Connections" or located in the top block of main parameters.
After moving to the desired section, a menu will open in front of you, where you need to select an item Wi-Fi hotspotThis is where all the key controls for your virtual router are located. The switch at the top of the screen activates the feature, making the device visible to other devices. However, simply turning on the switch isn't enough to ensure secure and stable operation.
⚠️ Note: When you first turn it on, the system may request permission to use geolocation. This is a standard Android requirement for network scanning; failure to do so may result in unstable access point operation.
Next, pay attention to the network name (SSID) and password. By default, Xiaomi generates the phone model name, which isn't always convenient. Recommended Change the name to something more descriptive and set a complex password using a combination of letters and numbers to prevent unauthorized access from neighbors. Changes are saved automatically when you exit the menu.
☑️ Pre-launch check
Setting up frequency range and safety standards
One of the most important and often overlooked settings is frequency band selection. In the access point menu, usually under the "Access Point Setup" or "Advanced" subsection, you can find this option. AP rangeHere the user is offered a choice between 2.4 GHz And 5 GHzUnderstanding the difference between them is critical to ensuring compatibility with all your devices.
Range 2.4 GHz is the most versatile and compatible. It penetrates walls better, but has a lower speed and is very noisy in apartment buildings. Range 5 GHz Provides high data transfer rates and is less susceptible to interference, but has a shorter range and may not be supported by older laptops or tablets. The choice depends on your current needs: speed or range.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Speed | Up to 150 Mbps | Up to 866 Mbps and higher |
| Range | High | Average |
| Penetration of walls | Good | Bad |
| Compatibility | Almost 100% | Only modern devices |
This section also configures the security standard. Always select WPA2-Personal or WPA3-Personal, if your devices support the new protocol. Using the outdated WEP standard or an open network makes your data vulnerable to interception. Modern versions of MIUI also offer an option to select the protocol version, which is best left as is. Auto for maximum compatibility.
Hiding the network and managing connected devices
To enhance privacy, Xiaomi owners can use the SSID hiding feature. This option is located in the same access point settings menu and is called Hide network or Stealth modeWhen this setting is enabled, your phone stops broadcasting the network name, and it won't appear in the list of available Wi-Fi networks on other devices.
To connect to a hidden network, the user must manually enter the exact network name (SSID) and password in the receiving device's Wi-Fi settings. This creates an additional barrier to accidental connections, although it doesn't provide complete protection against sophisticated hackers using traffic sniffers. Nevertheless, it's a useful feature for office environments or crowded areas.
Managing currently connected clients is done through the "Connected Devices" section. This displays a list of all devices currently consuming your data. You can see the device name, its MAC address, and the amount of data transferred. The system allows you to block unwanted users with one click by adding them to the blacklist, which will immediately stop all data transfer to that address.
Is it possible to find out what exactly connected users are doing?
No, your phone's standard features only show connection status and traffic volume. Viewing packet contents (images, messages) requires specialized sniffing software and root access, which is beyond Android's standard functionality.
It's important to check this list periodically, especially if you notice a sudden drop in your mobile internet speed. An unauthorized connection can not only consume your data but also reduce network response speed due to the limited bandwidth of your smartphone's Wi-Fi module.
Energy saving and sleep timer
Using your smartphone as a hotspot is a power-hungry process that quickly drains the battery. MIUI/HyperOS is equipped with intelligent mechanisms for monitoring power consumption. The hotspot settings often include an option to Sleep timer, which allows you to set a time after which Wi-Fi will turn off automatically if no one is connected to it or if there is no activity.
Additionally, pay attention to your system battery settings. Aggressive power saving can kill background internet tethering, especially if your phone's screen is off. To avoid this, go to battery settings, find the "Tethering" app or the corresponding system process, and set a strategy. No restrictions.
⚠️ Caution: When using Wi-Fi hotspots, your phone may become very hot. Avoid using heavy cases while using the router, and don't leave the device in direct sunlight or on soft surfaces that block heat dissipation.
There's also a feature that turns off the hotspot when no devices are connected. This feature is activated by a separate switch and is useful for those who forget to turn off the tethering mode. This prevents unnecessary battery drain in your bag or pocket when you've already stopped using the internet on your tablet.
USB modem: an alternative to wireless transmission
A wireless connection isn't always the best solution. If you need maximum stability, minimal latency (ping), and simultaneous device charging, a wired connection is better. USB modem Allows you to stream internet from your phone to your computer via cable, eliminating signal loss and radio interference.
To activate this mode, you need to connect your smartphone to a PC or laptop via a USB cable. Then, in the settings menu, where you can find the Wi-Fi hotspot, the option will become active. USB modemIt needs to be switched to the "On" position. The computer's operating system will automatically recognize the new network connection and install the necessary drivers.
The advantages of this method are obvious: data transfer speed is limited only by the USB port and mobile internet speed, not by Wi-Fi standards. Furthermore, the phone charges while in use, offsetting the power consumption. However, it's important to remember that sharing internet via USB and Wi-Fi from the same phone is usually impossible—the systems switch between the two modes.
Troubleshooting and fixing connection errors
Despite a well-functioning system, users may encounter common problems. It often happens that a laptop sees the network but is unable to connect, displaying the error "Failed to connect." In this case, the first thing to check is whether mobile Internet Check the phone itself and see if there's a balance. Without an active data stream from the external network, the hotspot won't work.
Another common issue is devices not detecting the network at all. Resetting the access point to factory settings or changing the broadcast channel in the advanced settings (if this option is available in your firmware version) can help. Sometimes, simply restarting the Wi-Fi module or completely rebooting the smartphone, which clears the network service cache, can help.
- 📶 DNS Error: If you have internet access but the pages aren't loading, try setting up a static DNS (e.g. 8.8.8.8) in the connection settings on the receiving device.
- 🔋 Fast discharge: Make sure Super Power Saving mode, which blocks background network activity to save battery life, is not enabled.
- 📡 Unstable signal: Try changing the band from 5 GHz to 2.4 GHz or move to an area with better cellular network reception.
In some cases, the problem lies with the telecom operator. Some data plans prohibit or limit tethering. The operator can detect this based on the TTL value. Bypassing the restrictions requires more complex manipulation of system files or root privileges, which is not recommended for regular users due to the risk of voiding the warranty.
Why does my Xiaomi phone drain quickly when the hotspot is turned on?
When operating in AP mode, the Wi-Fi module consumes significantly more power than in client mode. It constantly broadcasts a signal and processes requests from connected devices. Furthermore, if the cellular signal is weak (1-2 bars), the phone increases its transmit power, which, combined with the Wi-Fi module, leads to intense heating and rapid battery drain.
Is it possible to share Wi-Fi if the phone is connected to another Wi-Fi?
This feature (Wi-Fi Repeater) is available on most modern Xiaomi smartphones running Android 10 or higher, as well as on models with dual-band Wi-Fi modules. However, it doesn't work on all models. You can check this by trying to enable the hotspot while the phone is already connected to a Wi-Fi network. If the system switches you to mobile data, it means the device doesn't support both client and hotspot mode simultaneously.
How to change the MAC address of an access point on a Xiaomi?
In the default MIUI/HyperOS settings, the ability to change the access point's MAC address is hidden. This is done at the system level for unique identification. Changing the MAC address typically requires root access and the use of specialized apps or editing system configuration files, which is a complex procedure for advanced users.
