Modern smartphones of the line Xiaomi Redmi Mobile devices have long ceased to be mere calling devices, becoming full-fledged mobile hubs capable of providing internet access to an entire office while traveling or at the dacha. Enabling modem mode is a basic but critical feature that allows you to transform a mobile 4G or 5G signal into a stable wireless network. Users often need to quickly share data with a laptop or tablet, and understanding the intricacies of the operating system is crucial. MIUI or HyperOS here becomes the decisive factor for success.
The process of activating the access point on devices Xiaomi Each operating system has its own unique features that distinguish it from stock Android. The system has advanced security and power-saving features that can interfere with normal data sharing if not configured correctly. In this article, we'll cover all configuration steps in detail, from basic enablement to fine-tuning frequency bands and managing connected clients.
Basic activation of the access point via the curtain and settings
The fastest way to launch tethering is using the quick access panel, but for initial setup, it's best to use the full system menu. This will allow you to set a secure password and choose a network name to prevent neighbors or passersby from accessing your data. The standard path in current firmware versions is as follows: open Settings, then go to the section Access point and modem.
Inside this menu you will see a switch Wi-Fi hotspot, which needs to be activated. The system may warn you that tethering will increase battery consumption, and this is true: the radio module starts working in enhanced mode, broadcasting a signal constantly. Once enabled, nearby smartphones will be able to access the network with your device's model name, for example, Redmi Note 12.
⚠️ Attention: Before sharing your internet, make sure your carrier plan allows you to use your phone as a modem. Some carriers block data sharing or charge for it separately from your main gigabyte package.
To change network settings, click on the name of the active access point. Here you can change the SSID (network name) to something more recognizable and set a strong password using encryption. WPA2-PersonalIt is not recommended to leave the network open, as transmitted data can be intercepted by malicious users, especially if you are in a public place.
Advanced frequency settings and device compatibility
One of the key features of setting up distribution on Xiaomi The ability to select a frequency range is a plus. By default, the system uses the 5 GHz band, which provides high speed but has a shorter range and poorer wall penetration. If your client devices (old laptops or tablets) don't see the network, you'll need to switch to the 2.4 GHz standard.
To do this, find the item in the access point menu Setting up an access point or AdditionallyYou'll be able to select a frequency range. Using 2.4 GHz guarantees maximum compatibility, as this standard is supported by virtually every device with a Wi-Fi module released in the last 15 years. However, speeds in this range may be lower due to congestion in the airwaves from neighboring routers.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 300-450 Mbps | Up to 866 Mbps and higher |
| Range | High (up to 30-40 m) | Medium (up to 15-20 m) |
| Penetration of walls | Good | Low |
| Compatibility | Almost 100% of devices | Only modern gadgets |
You can also set a traffic limit in the advanced settings. Function Traffic limit Allows you to set the data limit after which the hotspot will automatically turn off. This is a useful option for controlling costs if you don't have an unlimited data plan. You can set the threshold to 1 GB, 5 GB, or any other value that suits your usage scenario.
Managing Connected Clients and Security
You can control who is connected to your network through the menu. Connected devicesThis section displays a list of all devices currently using your data. You can see the devices' MAC addresses and the amount of data transferred to them, which helps identify "freeloaders" who might have guessed your password.
If suspicious activity is detected, the system allows you to instantly block a specific device. Simply click on the client's name and select the block option. This will block network access for that MAC address, even if the password remains the same. This is more effective than changing the password again if you want to allow access to friends but block strangers.
- 🔒 Blacklist: Add unwanted devices to the blacklist for permanent blocking.
- 👁️ Monitoring: Monitor the number of connections in real time through the widget in the curtain.
- 🚫 Number limit: Set the maximum number of connected devices (usually up to 10) to avoid overloading the channel.
In such cases, use the MAC address as a guide, comparing it with the address on the sticker under the laptop battery or in the phone settings.
Network visibility issues and solutions
Users often encounter a situation where the access point is Redmi It's enabled, but other devices simply don't see it in the list of available networks. This could be caused by a temporary software glitch in the Wi-Fi module or a frequency conflict. The first step should always be to turn access point mode off and on again, every 10-15 seconds.
If restarting doesn't help, check your hidden network settings. In some versions MIUI There's a "Hide Device" option that makes the access point invisible to general scanning. You can only connect to this network by manually entering the SSID. Make sure this option is disabled if you want the network to appear in the default view.
⚠️ Attention: The settings interface may vary slightly depending on the version of the shell (MIUI 12, 13, 14, or HyperOS). If you can't find the item, search for "access point" in the settings.
Another possible cause is a full network service cache. In this case, resetting your network settings can help, but be careful: this will delete saved passwords for all previously connected Wi-Fi networks. Before resetting, make sure you remember the passwords for your home and work networks.
What to do if the network is visible but does not connect?
Often, the problem lies in the incorrect encryption type or password. Try temporarily setting a simple password consisting of numbers to eliminate typing errors. Also, check whether the client device has a static IP address that conflicts with the range of addresses assigned by the phone.
Energy saving and modem stability
Wi-Fi hotspot mode is one of the most energy-consuming processes on a smartphone. The active operation of the radio frequency module and processor leads to rapid heating of the case and draining of the battery. Xiaomi has aggressive power saving algorithms that can automatically turn off the hotspot if the screen is dark for a certain amount of time.
To prevent accidental shutdown, you need to set a sleep timer. In the access point menu, find the item Turn off the access point automatically and set it to "Never" or the maximum time interval. This will ensure the network remains stable even if you're not actively using your phone while sharing.
- 🔋 Battery optimization: Add the Hotspot app to the power saving exceptions list.
- ❄️ Cooling: Remove the case from your smartphone when using it for a long time to avoid overheating.
- 🔌 Nutrition: If possible, keep your phone connected to a charger.
It's also worth keeping in mind that when actively downloading large files on client devices, the phone may become noticeably hot. In hot weather or direct sunlight, this can lead to throttling (reduced performance) and a drop in internet speed. Try keeping the device in the shade or on a hard surface to improve heat dissipation.
☑️ Checklist for stable distribution
Using a USB modem as an alternative to Wi-Fi
If wireless sharing doesn't provide the required stability or the speed isn't satisfactory, consider a wired USB connection. USB modem Allows you to transfer internet from your phone to your computer via a cable, eliminating signal loss and providing additional charging for your smartphone while it's running.
To activate this mode, connect your phone to the PC with a cable, then go to the menu Access point and modem and activate the switch USB modemThe computer will recognize the new network connection as if you had connected an Ethernet cable. This method is especially useful for desktop PCs without Wi-Fi adapters.
The advantage of a USB connection is the absence of electromagnetic radiation in the room and lower power consumption compared to Wi-Fi broadcasting. Furthermore, a cable connection is less susceptible to external interference, which is critical for video calls or online gaming, where ping is crucial.
Why does the access point turn off by itself after 10 minutes?
You likely have the automatic power-off timer enabled to save power. Check the settings under "Turn off hotspot automatically" and change the timer to a longer time or disable it completely. This can also happen if no one is connected to the network.
Is it possible to share Wi-Fi if the phone is connected to a Wi-Fi router?
On most modern models Xiaomi Redmi Android 10 and above support this feature (Wi-Fi Repeater). The phone receives a signal from one router and distributes it further, changing the SSID. However, this drains battery life and can reduce overall speed.
What is the best password to use for a hotspot?
Use a combination of uppercase and lowercase letters and numbers, at least 8 characters long. Avoid simple sequences like "12345678" or your date of birth. Encryption must be set to WPA2-Personal or WPA3, if available.
Does tethering affect battery life?
Yes, charge and discharge cycles are depleted faster, and heat generated during active use can negatively impact battery chemistry during use. Try not to leave your phone in hotspot mode for days on end.
