Today’s Xiaomi smartphones have powerful functionality that is often underutilized, and one of the most useful hidden features is modem mode, which allows you to turn your smartphone into a full-fledged router or a new router. USB-Modem in minutes, which is indispensable for travel, in the absence of wired Internet or in situations where you need to provide a stable connection for a laptop or tablet.
However, many users have difficulty initially configuring. The MIUI or HyperOS shell interface has its own features that can confuse a beginner. In this article, we will detail all the ways to make a Xiaomi modem, and eliminate common connection errors, you will learn to use all available data interfaces as efficiently as possible.
It's important to understand that the choice of method depends on your goals: If you want maximum speed for downloading files, cable connection is suitable. To connect multiple devices, you better use a wireless protocol. We will consider each option so that you can choose the best scenario for using your gadget.
Preparation of the smartphone to work in modem modem
Before you start actively distributing traffic, you need to make sure that the device is ready to work. Basic setup does not require deep knowledge, but ignoring some parameters can lead to unstable network operation. First, check whether mobile data is activated in the notification curtain.
Then you should pay attention to your carrier's APN settings, which are the parameters that make it possible to connect correctly to the provider's network. If the Internet on the phone itself is slow or intermittent, then modem modem mode will also be problematic.
⚠️ Note: Before you turn on modem modem, make sure that your plan does not have a restriction on the distribution of Internet. Some operators block or tariff traffic coming through tethering, separately from the main package.
It's also worth checking the battery power. Active Internet mode significantly increases power consumption. If you're planning a long session, it's better to connect the device to a power source, which will prevent a sudden shutdown at an important point in your life.
Setting up USB-Xiaomi modem
The fastest and most stable way to turn a phone into a network device is to use it. USB-This method provides minimal delays and charges the battery at the same time. First, connect your smartphone to your computer using a high-quality cable.
After the physical connection, go to the settings menu, you need to find the section that provides additional connectivity, the path may vary slightly depending on the firmware version, but the logic remains the same, find the Wi-Fi hotspot and the modem.
☑️ Pre-insertion check USB-modem
In the menu that opens, activate the switch. USB-If the item is inactive (gray), the system may not see the cable or the computer does not have the necessary drivers.
When you turn on the computer tray, you'll see a new network icon, and the system will define the connection as a wired Ethernet connection, and the speed will be limited only by the phone's communication module and the standard. USB-port.
💡
Use the original cable or certified analogue with data support. Cheap "charging only" cables will not allow you to activate modem mode.
Organization of Wi-Fi access point
Wireless is the most popular mode because of its versatility, allowing you to connect laptops, tablets and other phones without unnecessary wires. To set up this feature, go to the Wi-Fi Access Point menu.
It is important to set the security settings correctly. By default, the network may be open or have a weak password. Click on the network name to change the SSID (name) and set a strong encryption key. WPA2-Personal is recommended.
Special attention should be paid to the frequency range. In the access point settings menu, select the 5 GHz band if your devices support this standard, which will provide faster data rates and less ether load.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Range. | 5 GHz | High speed, less interference |
| Canal | Automobile | Optimal frequency selection |
| Encryption | WPA2-Personal | Protection against burglary |
| Max. Devices. | 4-6 | Stability of connection |
Remember to set a limit on the number of devices you can connect to, and if a dozen devices try to connect to your network, the speed will drop critically, and the phone may overheat, and the optimal number is 3-5 active customers.
Use of Bluetooth panel
Although this method is considered obsolete due to low speed, it can still be useful in emergency situations.Bluetooth modem consumes less power than Wi-Fi, and allows you to connect devices that do not have a wireless connection. USB-port or Wi-Fi module (e.g., old PDAs or specific equipment).
To activate, you first need to pair the phone and the receiving device. Make sure that Bluetooth is on both devices and they see each other. After creating a pair, go to the modem settings and turn on the Bluetooth modem.
On your computer or second phone, you need to find your device in the list of available Bluetooth gadgets. Select the option of connecting over the network or PAN-Profile: The connection installation process can take up to 30 seconds.
The speed of the Bluetooth modem
The main disadvantage is low bandwidth. However, for background synchronization of mail or messengers, this option is quite useful and saves battery power for your Xiaomi.
Optimization and hidden settings
Xiaomi smartphone owners have access to advanced settings through an engineering menu or special commands. This allows you to fine-tune the behavior of the modem. For example, you can fix the type of network so that the phone does not switch between 3G and 4G/5G, causing connection breaks.
To access advanced network settings, type in dialer code ##4636##. From the menu that opens, select Phone Information. Here you can set your preferred network type, such as LTE Only, which will force the modem to only work in the speed standard.
⚠️ Warning: Be careful when changing the settings in the engineering menu. Incorrect settings may result in loss of signal or need to reset network settings.
Also, you should turn off traffic savings for applications that need to run in the background while the Internet is being dealt, go to the traffic settings and make sure that system processes are not limited, which is especially important for the stable operation of VoIP telephony or video conferencing.
Another useful life hack is the use of third-party applications to create virtual adapters, but this is rarely necessary on Xiaomi thanks to the built-in MIUI functionality.
Addressing common problems
Although easy to set up, users can encounter errors. Often the computer sees the phone as a storage device, but not as a network card, in which case try changing the USB mode in the debugging menu or simply reconnecting the cable to another port.
If you have internet on your connected device but the pages are not loading, check your DNS settings. Try manually writing 8.8.8.8 and 8.8.4.4 addresses in the network connection properties of your computer.
💡
The main reason for the unstable operation of the modem is a weak signal of the cellular network. Before turning on the distribution, make sure that the reception indicator shows at least 3 divisions.
Overheating is another common problem. When you run in hotspot mode for long periods, especially at 5GHz, the phone can get very hot. Remove the case for better heat sink and don't put the phone on soft surfaces.
In some cases, carriers block the distribution by determining the TTL of packets, which requires more in-depth system intervention and may violate the terms of the contract with the operator, so we do not recommend using complex methods of bypassing unnecessarily.
Safety in the use of public modem
When your smartphone becomes an access point, it takes over the router, which puts the security of the connected customers in charge. Always use complex passwords that are made up of different register letters, numbers and special characters.
Don’t connect unfamiliar devices to your network. An attacker who gains access to your Wi-Fi can intercept traffic or use your connection for illegal activities. In the settings of the access point Xiaomi has a function “White list”, allowing you to allow connection only to specific devices on the Internet. MAC-address.
Check the list of connected customers in the modem menu regularly, and if you see an unknown device there, immediately change your password and block the intruder, which ensures that your personal data is safe.
