One device has a stable mobile internet connection and another requires a network connection, and Android ecosystem owners often use a bundle of smartphones from different manufacturers, such as Xiaomi as a modem and Samsung for work or entertainment. Technology of data transmission via Wi-Fi, Bluetooth or USB-cable is built into the operating system kernel, but shell interfaces MIUI One UI may have their own characteristics.
The process of organizing a local network between devices does not require root rights or installing third-party software. All the necessary tools are in the standard settings menu, which is open by default. However, in order to ensure a stable and secure connection, you need to properly configure encryption settings and select the appropriate signal frequency. In this article, we will discuss in detail all the steps of setting up the access point and methods for eliminating common errors.
The main advantage of using the Xiaomi and Samsung bundle is the high compatibility of data protocols. Both manufacturers are actively using Wi-Fi Direct standards and modern WPA3 security protocols, which ensures reliable protection of transmitted traffic. Understanding the basic principles of communication modules will allow you to quickly deploy a network anywhere in the world, whether it is an office, train or remote location without wired Internet.
Preparation of Xiaomi device to work in modem modem
Before you start broadcasting the signal, you need to make sure that the Xiaomi device is activated mobile data transfer. Without this step, all further actions will be meaningless, since the smartphone will have nothing to broadcast to the external network. SIM-cards and signal level at the top of the screen, as weak reception directly affects the speed of distribution.
Then you go to system settings. The path may vary slightly depending on the version of the MIUI shell or HyperOS, but the logic remains the same. You need to find the partition responsible for connecting and sharing data, usually located at the top of the list of parameters or in a separate menu "Connections and Sharing".
- 📱 Make sure that the mobile internet is on and working correctly.
- 🔋 Check the battery level, as modem modem is very energy consuming.
- 📶 Make sure that flight mode is not turned on, blocking all wireless interfaces.
⚠️ Attention: With the active distribution of the Internet, the smartphone battery discharges into 2-3 It is recommended to keep the device connected to the charger or power bank to avoid sudden shutdown.
An important step is to check the network name and password settings. By default, the system often generates a random access point name, which can be difficult to search. You can change the SSID (network name) to any combination of characters you understand, and set a strong password to prevent unauthorized access to your traffic.
Configure the settings of the Wi-Fi access point on MIUI
When you enter the hotspot menu, you will see the option “Setting up the Wi-Fi hotspot” — which is where the key parameters that determine how your Xiaomi device will be seen by Samsung and other gadgets are located.
Modern smartphones support two main ranges: 2.4 GHz and 5 GHz. The first option provides longer range and better wall penetration, but has a lower data rate. The second range, 5 GHz, offers significantly higher speeds and less interference, but its range is smaller and older devices may not see it.
For most current Samsung Galaxy models, the best choice is 5GHz if the devices are close to each other. If you plan to use the Internet in another room or in a lot of obstacles, you better switch to 2.4GHz for connection stability. Remember to save the changes by clicking the tick in the upper right corner of the screen.
Hidden APN settings
You can also set a traffic limit or a shutdown timer on this menu, and the "Disable Access Point" feature saves battery life if no one is connected for a long time, and it's a useful option to activate if you forget to turn off modem mode after use.
The process of connecting Samsung smartphone to the network
Once the hotspot on Xiaomi is activated, you can go to the setting of the receiving device. Take a Samsung smartphone and unlock the screen. Network search is standard for any version of Android, but we will describe it in detail to eliminate any misunderstandings.
Open the settings and select the Wi-Fi section. Make sure the Wireless Power slider is active. The device will start scanning the surrounding space and in a few seconds display a list of available networks. Find the name (SSID) you set on the Xiaomi phone or the standard model name in the list.
| Parameter | Value on Xiaomi | Action on Samsung |
|---|---|---|
| Network name (SSID) | Manually specified | Select from the list |
| Password. | Minimum 8 characters | Enter when connected |
| Security protocol | WPA2/WPA3 Personal | Automatically. |
| Frequency | 2.4 GHz or 5 GHz | Automatically. |
Click on the network name. The system will request a password. Enter the character combination set to Xiaomi and click "Connect." If the password is correct and the signal is sufficient, the status "Connected" will appear on the screen and the Wi-Fi icon will appear in the status bar. From now on, traffic to Samsung will go through the Xiaomi mobile network.

Alternative ways to transmit the Internet: USB and Bluetooth
Wi-Fi is not always the best solution. In situations where maximum stability is required or where the battery power of the receiving device is saved, it is worth considering a wired connection. USB-Kaela allows you to simultaneously transfer data and charge a Samsung smartphone, which is impossible when working through a Wi-Fi module.
For implementation USB-Connect both devices with a high-quality cable. On Xiaomi, the access point menu (or notification curtain with the cable connected) needs to activate the item "USB-At Samsung, at this point, a request for debugging permission or use may appear. USB, Computers and laptops also work very well with this method, defining the phone as a network card.
A Bluetooth modem is an option for emergencies when other methods are not available, and the data rate is much lower, and it is unlikely to be suitable for watching videos or downloading large files, but for texting, emailing or navigation, this method is quite suitable and consumes minimal energy.
- 🔌 USB-The modem provides the highest connection stability.
- 🔋 Wired connection allows you to charge the receiving device.
- 📉 Bluetooth is only suitable for lightweight tasks due to low speed.
⚠️ Note: When connecting to USB Drivers can automatically install on your computer. If that doesn't happen, make sure your PC has Android components installed. USB Driver or Mi program PC Suite.
It is important to note that when using USB-Some antivirus software on the computer may perceive the phone as a potentially dangerous network device, in which case you need to add the device to the exclusion list. Also make sure the cable is in good working order and supports data transfer, not just charging, as cheap cables often lack internal contacts to transmit information.
💡
Use the original USB-C cable that came with your smartphone. Cheap counterparts often can't withstand long loads and can cause data rate drops or ports to overheat.
Solving Common Connection Problems
Even with the right setup, there can be situations where Samsung sees the network but doesn't connect, or there's a connection and the Internet doesn't work. IP-address or malfunction DHCP-It's a simple restart of the Wi-Fi module on both smartphones.
Another common problem is encryption protocol incompatibility: If Xiaomi has WPA3 installed, and Samsung is an old model, it may simply not see the network or refuse to enter a password. The solution is to switch the security type to WPA2-Personal in the access point settings.
It's also worth checking the date and time settings. If one device has a time lost, the security certificates may not pass the check, and the connection will break immediately after you set it up. Synchronize time over the network on both devices to rule out this error.
💡
If the Internet does not work with Wi-Fi connected, try changing the IP settings from DHCP to Static on the receiving device in the network properties and manually prescribe the address, for example, 192.168.43.100.
In rare cases, the problem lies with carriers, some data plans block the ability to distribute the Internet (Tethering technology), the operator sees that the traffic is not from the smartphone, and blocks the connection, and you can bypass this restriction by changing the TTL parameter, but this requires deeper knowledge and perhaps root rights, which is not recommended for ordinary users.
Safety and optimization of traffic consumption
When you share the Internet, you become the administrator of your own mini-network. It's important to understand who's connected to your access point. In the access point menu on Xiaomi, there's a section called Connected Devices, where you display all active gadgets. If you see an unfamiliar device, change your password immediately.
To save traffic on Samsung, you can enable data saving mode, which will prevent automatic downloading of app updates, high-resolution photo sync and other background processes that can quickly exhaust your mobile package. Set a traffic limit in the access point menu itself, so that the system automatically turns off the distribution when it reaches a specified volume.
Guest mode is another useful feature, which allows you to create a temporary network with limited time or traffic limits for guests, and this is true if you need to quickly transfer a file or show a site, but you do not want to give permanent access to your main network.
