Modern smartphones Xiaomi And Redmi with shell MIUI have long since evolved into full-fledged pocket computers, capable of not only consuming content but also actively sharing an internet connection. The mobile hotspot feature is one of the most sought-after features, allowing for quick access Wi-Fi access to a colleague's laptop, tablet, or device without a wired network. However, default system settings sometimes conceal nuances that can significantly impact data transfer speed and connection stability.
Unlike pure AndroidThe proprietary firmware of a Chinese manufacturer has its own menu and network module logic. Users often encounter situations where internet access is unstable, drains the battery quickly, or is completely unavailable to other devices. Understanding the operating principles roaming and frequency ranges within the ecosystem MIUI will help to avoid typical configuration errors.
In this article, we'll walk you through the entire process, from enabling the basic feature to fine-tuning hidden settings that aren't always immediately obvious when you first explore the interface. You'll learn how to choose the right frequency band, limit the number of connected devices, and secure your network from unauthorized access. Proper setup will turn your smartphone into a reliable internet connection for any device.
Basic hotspot setup in MIUI
The process of activating modem mode in the shell MIUI The developers have simplified it as much as possible for comfortable use. To get started distribute InternetSimply pull down the notification shade and tap the "Access Point" icon, or delve deeper into the system settings for more detailed configuration. The standard path usually looks like this: Settings → Wi-Fi Hotspot, where the main switches are located.
When first turned on, the system will prompt you to set a network name (SSID) and password, which will be used to authenticate clients. It is recommended to immediately set a strong encryption key using the standard WPA2 or WPA3to prevent unauthorized individuals from intercepting your traffic in public places. Simple passwords like "12345678" are easily guessed by automated means, putting your personal data at risk.
- 📱 Click the gear icon in the access point menu to access advanced options.
- 🔒 Select your security type WPA2-Personal for maximum compatibility with older devices.
- 📡 Make sure the frequency range is set to automatic or selected manually depending on your needs.
⚠️ Note: In some versions MIUI When you turn on the hotspot, mobile Internet on the phone itself may be automatically disabled unless the corresponding option is activated in the developer menu or network settings.
The settings interface may vary slightly depending on the firmware version (Global, China, EU), but the key elements remain the same. If you plan to use tethering for extended periods, it's best to remove the protective case for improved heat dissipation.
Choosing a Frequency Band: 2.4 GHz vs. 5 GHz
One of the most important parameters affecting the speed and range of your improvised network is the choice of operating frequency. In the access point settings Xiaomi a choice between ranges is often available 2.4 GHz And 5 GHzEach of them has its own physical limitations and advantages that must be considered when connecting different types of client devices.
The 2.4 GHz band is more versatile and compatible with the vast majority of gadgets released in the last 15 years. It has better penetration through walls and obstacles, providing coverage over a larger area. However, data transfer speeds are limited and are highly dependent on airborne noise from nearby routers and household appliances.
The 5 GHz frequency, on the other hand, offers significantly higher speeds and connection stability, which is critical for watching 4K video or playing online games. However, the signal range in this range is significantly shorter and penetrates building structures less effectively, so devices must be connected in close proximity to the smartphone.
Why can't some devices see the 5 GHz network?
Not all network cards support the 802.11ac or ax standard. Older laptops and budget tablets may not physically have a module for the 5 GHz band, so they simply won't show your network in the list of available ones. Switch to 2.4 GHz for compatibility.
For modern flagship smartphones and laptops, 5 GHz is the optimal choice, as it allows you to fully realize the potential of 4G/5G mobile internet. However, if you plan to connect older devices, IoT devices, or gadgets with simple communication modules to the access point, it's best to stick with the standard 2.4 GHz band to avoid connection issues.
Limiting the number of connections and managing traffic
Functional MIUI It allows you not only to share the internet but also to strictly control who has access to it. The access point menu includes a "Connected Devices" option, which displays all current clients and their MAC addresses. You can block an unknown device at any time by simply clicking on it and selecting the appropriate menu item.
In addition to manual blocking, the system offers a limit on the number of simultaneous connections. This is a useful feature for saving battery life and preventing bandwidth congestion when dozens of devices are trying to connect to your phone. A reasonable limit is usually considered to be 3-5 devices, ensuring comfortable speeds for all users.
| Parameter | Recommended value | Impact on the system |
|---|---|---|
| Device limit | 3-5 pieces | Reduces CPU and battery load |
| Wi-Fi timeout | 10 minutes | Automatically turns off the point when there are no clients |
| IP range | By default | Ensures correct issuance of addresses to clients |
It's also worth noting the timeout feature, which automatically turns off the hotspot if no one is connected for a set period of time. This prevents you from forgetting to turn off tethering and wasting battery life. This setting is located in the same menu as password management.
☑️ Network security check
Troubleshooting visibility and connectivity issues
Users often encounter a situation where the hotspot is enabled, but other devices simply don't see it in the list of available networks. First, check to see if the network name (SSID) is hidden in the privacy settings. If the hiding feature is enabled, you'll have to manually enter the network name on the connecting device, which isn't always convenient.
Another common cause of problems is an IP address conflict or a malfunction in Android network services. In this case, a simple restart of the communication module helps: turn on airplane mode for 10-15 seconds, then turn it off. This will force the device to re-register with the carrier's network and reset the network settings.
⚠️ Note: If you use a VPN service on your phone, the hotspot may not work or may not work correctly. Some apps block traffic forwarding through the hotspot for security reasons.
If your device connects but the internet isn't working ("No internet access"), check your DNS settings. Mobile providers sometimes require specific settings or block traffic distribution to certain ports. In such situations, changing your DNS to public addresses, such as those from Google or Cloudflare, may help, although this won't work in the mobile interface. MIUI This is not always done explicitly.
Power consumption and battery optimization
Hotspot mode is one of the most power-hungry smartphone usage scenarios. The radio module operates at full power, constantly transmitting data, which leads to rapid battery drain and heat generation. Device owners Xiaomi Those with fast charging technology have better luck, but even they can notice a decrease in battery capacity over time if they use the feature frequently.
To minimize damage, it's recommended to reduce screen brightness to a minimum or turn off the display completely while tethering. The screen is the second-largest power consumer after the radio, and turning it off will significantly extend the battery life of the modem. It's also a good idea to close background apps that may be consuming data.
- 🔋 Use the original charger when using the hotspot for a long time.
- ❄️ Remove the thick protective case to improve case cooling.
- 📉 Disable photo and cloud syncing while sharing.
System MIUI has built-in overheat protection mechanisms that can forcibly disable the hotspot or reduce data transfer speeds if the processor temperature reaches critical levels. If you notice your phone getting hot, take a break and let it cool down to prevent battery degradation.
Additional features and hidden settings
For advanced users who want to get the most out of their Xiaomi At most, there are additional configuration methods available through the engineering menu or ADB commands. For example, you can change the transmitter's signal strength or set up static IP addresses for clients, although the standard interface doesn't provide these capabilities.
One useful feature is the ability to generate a QR code for quick connection for guests. Instead of typing a complex password, you can share your phone screen, and your contact can connect by simply scanning the code with the camera. This option is usually available directly under the hotspot name in the settings menu.
Also worth mentioning is the USB modem feature, which allows you to share your internet connection via a cable. This method provides a more stable connection, lower latency (ping), and simultaneously charges your phone, making it ideal for desktop use with a laptop.
⚠️ Note: Settings interfaces and available features may vary depending on the Android version and specific MIUI version (Global, Russia, China). If you don't see this option, it may be hidden in your software version.
Regularly updating your smartphone's firmware ensures you receive the latest security patches and improvements to network modules. Xiaomi periodically releases patches that eliminate connection bugs and improve compatibility with various client device operating systems.
Why does my Xiaomi hotspot turn off by itself after a while?
This is a standard system behavior to save power. If no device is connected to the access point for the time specified in the timeout settings (usually 1, 5, or 10 minutes), the system automatically powers off the module. You can change this interval or disable automatic power-off in the access point settings menu.
Is it possible to share WiFi if the phone is connected to a WiFi network?
On most modern smartphones Xiaomi with Android 10 and above and recent versions MIUI This feature (Wi-Fi Repeater) is available. However, on older models or in some regions, enabling the hotspot may automatically disable Wi-Fi reception, switching the phone to 4G mobile data.
How to hide your network name (SSID) on Xiaomi?
In the standard access point settings menu, find the "Hide Device" or "Hide SSID" option. Once enabled, the network will no longer appear in the general list, and you'll need to manually enter the exact network name on the client device to connect.
Is it safe to use public DNS when sharing internet?
Using public DNS (e.g., Google 8.8.8.8) on your phone can speed up website loading and bypass ISP blocking, but all client traffic still goes through your phone. For complete security, we recommend using trusted DNS services that support DNS-over-HTTPS encryption, if your firmware supports it.
