Modern smartphones Xiaomi And Redmi have long ceased to be mere devices for making calls, turning into powerful tools for work and entertainment. One of the most sought-after features in a user's arsenal is the ability to turn a gadget into a full-fledged Wi-Fi routerThis is especially relevant when traveling, at the dacha, or in offices where wired internet is unavailable or blocked by the administrator.
The process of setting up an access point in MIUI or HyperOS is intuitive, but it hides many nuances. Proper configuration allows you to not only ensure a stable connection for your laptop or tablet, but also effectively manage it. charge consumption batteries, as well as control connected devices.
In this article, we'll cover every step of activating tethering mode in detail, from basic settings to advanced security options. You'll learn how to optimize data transfer speeds and avoid common mistakes smartphone owners often make. Xiaomi.
Basic hotspot setup in MIUI and HyperOS
The first thing you should do is enter the settings menu. The shell interface MIUI The details may vary depending on the Android version and regional firmware, but the logic remains the same. You need to find the section responsible for wireless connections, where the desired functionality is hidden.
Click the gear icon on your desktop or in the notification shade. In the menu that opens, find Wi-Fi hotspotIn some firmware versions it may be hidden inside a folder Additional functions or Connection and sharingThis is where the switch that activates the Internet sharing mode is located.
Once the slider is turned on, the phone will immediately begin broadcasting the network. However, the default network name (SSID) and password may be too difficult to remember or, conversely, too generic, which is undesirable from a security standpoint. It's recommended to immediately go to the profile settings to set a descriptive name and a strong access key.
☑️ Check before switching on
Please note that when activating the hotspot, the system may warn you about increased power consumption. This is normal. operating system, as the radio module switches to intensive operation mode. If you're planning a long session, it's best to connect your smartphone to a charger.
Choosing a Frequency Band: 2.4 GHz vs. 5 GHz
One of the key parameters affecting connection speed and stability is the choice of frequency band. In the access point settings Xiaomi It's often suggested to choose between 2.4 GHz and 5 GHz. Understanding the differences between them will help you optimize your network for specific tasks.
The 2.4 GHz band is more versatile and compatible with older devices that don't support modern communication standards. It provides better coverage and signal penetration through walls, but is often congested by neighboring routers and household appliances, reducing actual speeds.
The 5 GHz band offers significantly higher data transfer rates and is less susceptible to interference. However, its range is shorter, and the signal penetrates obstacles less effectively. If your laptop or tablet is in close proximity to your phone, choosing 5 GHz is optimal for video streaming or online gaming.
The impact of range on battery
Using the 5 GHz band requires more power from the smartphone's radio module, which results in faster battery drain compared to 2.4 GHz. If battery life is a priority, choose 2.4 GHz.
In some cases, the client device may not see the network if an incompatible band is selected. If your laptop doesn't detect the access point, try changing the frequency in your phone's settings to 2.4 GHz. This is the most common compatible standard, which is supported by almost any Wi-Fi adapter.
Setting up security and hiding the network
The security of transmitted data should be a priority, especially when using public networks or when sharing internet in crowded areas. MIUI allows you to choose the encryption type, and here you shouldn't skimp on security.
Always choose an encryption protocol WPA2 PSK or WPA3If your devices support the new standard, use an open network or outdated WEP, making your traffic vulnerable to interception by attackers who could gain access to passwords and personal information.
For increased privacy, you can use the SSID hiding feature. This will prevent your network name from appearing in the list of available connections on other devices. To connect, you'll need to manually enter not only the password but also the exact network name.
⚠️ Note: Hiding your SSID isn't a complete protection against security professionals, but it does effectively prevent prying eyes from neighbors and automatic connections from unauthorized devices in crowded areas.
Remember to change your password regularly, especially if you've shared your network with third parties. A complex password containing mixed-case letters and numbers is virtually impossible to brute-force within a reasonable timeframe.
Managing connected devices and limits
Functional Xiaomi Provides convenient tools for monitoring who uses your internet. You can see a list of connected devices, their IP addresses, and their traffic consumption in real time.
The hotspot management menu often includes a data limit setting. This is a useful option if you have a limited data plan. You can set a threshold at which internet sharing will automatically stop, preventing unexpected charges.
You can also set a sleep timer. You can program your phone to turn off the hotspot after a certain amount of time or when no one is connected. This helps conserve battery if you forget to turn off tethering.
| Parameter | Description | Recommendation |
|---|---|---|
| Max devices | Connection limit | 4-6 devices |
| Range | Signal frequency | 5 GHz for speed |
| Encryption | Type of protection | WPA2/WPA3 |
| Time-out | Auto power off | 10 minutes |
Limiting the number of connected devices is an important feature. Without setting a limit, theoretically, multiple devices could connect to your network, leading to a critical drop in speed and overheating of the smartphone. The optimal limit is considered to be 4-5 devices.
Troubleshooting connection and speed issues
Despite the stability of work Android, users may encounter situations where devices don't see the network or the internet is unstable. Often, the problem lies in APN settings or IP address conflicts.
If your laptop detects the network but won't connect, try resetting your phone's network settings. This will reset all Bluetooth, Wi-Fi, and mobile data settings to factory defaults, eliminating any software configuration errors.
Another common cause of slow speeds is a weak cellular signal. A hotspot can't operate faster than your carrier's incoming connection. Make sure the indicator on the screen shows 4G or LTE, not EDGE or 3G.
⚠️ Note: If you use a VPN on your phone, shared internet may not work for connected devices by default. Special traffic forwarding settings or the use of client apps are required.
In some cases, changing the Wi-Fi channel can help. If there are multiple networks in the same room, the channels may overlap. Using Wi-Fi analysis apps can help you find a free channel and manually enter it into the access point settings.
The impact of Wi-Fi distribution on battery and heating
Hotspot mode is one of the most power-hungry processes for a smartphone. The radio module simultaneously receives a signal from the tower and transmits data via Wi-Fi, causing the device's body to heat up significantly.
During prolonged use, it's recommended to remove the phone's case to improve heat dissipation. Overheating can lead to throttling (reduced processor performance) and accelerated degradation of the lithium-polymer battery.
There's a myth that using Wi-Fi is more harmful to a phone than regular use. In fact, it's overheating that's harmful. Monitoring the phone's temperature and not leaving it in direct sunlight or under a pillow will help it last longer.
To minimize the load, you can disable the search for other devices in the Wi-Fi and Bluetooth settings when not in use. This will reduce background radio activity and slightly extend battery life.
Additional features and hidden settings
For advanced users Xiaomi Offers access to advanced settings through the engineering menu or dedicated apps. However, even standard tools can achieve excellent results.
For example, you can configure the hotspot to automatically turn on when connecting to a specific Bluetooth device in your car. This is accomplished through automation scripts built into the shell or available through third-party utilities.
It's also worth mentioning the option of sharing the internet via a USB cable. This method provides the most stable speed and simultaneously charges the phone, eliminating the problem of battery drain, but it requires a physical connection.
⚠️ Note: The settings interface may vary depending on the MIUI version (12, 13, 14) and processor type (Snapdragon or MediaTek). If you don't see the option, check the menu location in the official documentation for your model.
Using a USB modem is often preferable for stationary work on a laptop, as it creates less electromagnetic radiation and does not occupy the Wi-Fi radio channel, allowing the phone to simultaneously connect to another wireless network.
Why does my phone battery drain quickly when the hotspot is turned on?
This is due to the radio module's dual function: it receives a 4G/5G signal from the base station and simultaneously transmits a Wi-Fi signal. Both processes require high voltage. Furthermore, active data transmission puts a strain on the processor, which also consumes power.
Is it possible to share Wi-Fi if there is no SIM card on the phone?
No, to share mobile data, you need an active SIM card with a data plan that includes a data plan. However, you can share the Wi-Fi your phone receives from another network (repeater mode), but this feature is not supported on all models. Xiaomi and requires Android 10 and above.
How can I find out the password for the created access point?
The password is displayed in the hotspot settings menu. Tap the eye icon or edit profile to see the current password. If you've changed it and forgotten it, you can reset the network settings to factory defaults, but then you'll have to set up the name and access key again.
Does Wi-Fi sharing affect the speed of mobile internet on the phone itself?
Yes, it does. The connection is shared between the phone itself and connected clients. If a connected laptop starts downloading large files, page loading speeds on the smartphone may significantly decrease due to the limited bandwidth of the radio module.
