In today’s world, a smartphone has long since ceased to be just a phone, becoming a universal tool for work and entertainment. Often there is a situation when you need to urgently connect a laptop or tablet to the global network, and free Wi-Fi is not nearby. This is where the Xiaomi Redmi owners come to the aid of a technology known as Tethering, which allows you to turn your gadget into a portable router.
Many users come across this term in their settings, unaware that the complex name hides the usual function of distributing the Internet. Understanding the principles of Tethering will help you not only quickly provide Internet to other devices, but also optimize traffic consumption, as well as secure the data transmitted. In this article, we will discuss in detail all aspects of the operation of this system in the shell of MIUI.
The essence of the process is that the mobile device acts as a gateway between the operator’s cellular network and connected customers. Xiaomi Redmi is famous for its flexible settings system, which allows you to finely manage the distribution parameters. This gives an advantage over standard Android smartphones, where the capabilities are often limited to basic functions.
The essence of Tethering technology and the principle of operation
Tethering comes from the English word for “tethering” or “binding.” In a mobile context, it means using a smartphone as a modem to provide Internet access to other devices. Unlike simple Bluetooth file sharing, it involves fully routing traffic over a 4G or 5G mobile network.
There are three main ways to implement this feature, each with its own power consumption and speed features. Xiaomi Redmi supports all current data protocols, making it a versatile tool.
- 📡 Wi-Fi hotspot is the most popular method, creating a wireless network around a smartphone with high data rates.
- 🔌 USB-modem – wired connection, providing maximum stability and at the same time charging the battery.
- 🔵 Bluetooth panorama – energy-saving option for transferring small amounts of data, suitable for older laptops.
It is important to understand that when activating any of these modes IP-Your smartphone’s address changes and it starts to function DHCP-servers for connected clients. MIUI It automatically reconfigures network interfaces to ensure seamless operation, but it is worth considering that the active use of Tethering significantly increases the load on the processor and radio module of the device.
⚠️ Note: When using Wi-Fi access point mode, the case of the smartphone can significantly heat up due to the simultaneous operation of the receiver and transmitter at high frequencies.
The technology works at the level of system services of the operating system, so it does not require third-party applications to activate it. SIM-A card with a connected packet of Internet traffic.Telecom operators often track the use of Tethering, as tariffs for smartphones and modems may differ.
Setting up a Wi-Fi hotspot in MIUI
The setting of the wireless access point in Xiaomi Redmi smartphones is intuitive, but hides a number of useful options. To get started, you need to go to the settings menu and find the section responsible for connecting and sharing data. The interface may vary slightly depending on the version of MIUI, but the logic remains the same.
First, you need to activate the mobile Internet, because you can't distribute Wi-Fi without it, and then the system is ready to configure the security settings and the network name, and properly configuring these settings will protect you from unauthorized access to your traffic.
To enter the settings menu, follow the following steps:
- Open the Settings app on the main screen.
- Go to Wi-Fi Access Point or via the Connect and Sharing path.
- Click on Setting up the Wi-Fi hotspot to edit the settings.
In the window that opens, you need to specify an SSID (network name) and password. It is recommended to use a complex password using different register letters and numbers to prevent brute force hacking. You can also choose a frequency range: 2.4 GHz provides better compatibility, and 5 GHz provides higher speed and less noise.
Special attention should be paid to the traffic limit that can be set right in this menu. Xiaomi Redmi allows you to automatically disable the access point after exhausting a given amount of data, which saves from unexpected costs.
☑️ Check before activating the access point
Use of the USB-stable-connection modem
When maximum speed and minimum latency are required, a wired connection through the wired network is the best choice. USB-This is a method known as cable. USB Tethering, often ignored by users, is devoid of many of the disadvantages of wireless communication, primarily the lack of radio interference and stable ping, which is critical for online games or video conferencing.
To activate this mode, you need to physically connect the Xiaomi Redmi smartphone to your computer or laptop using a high-quality cable. The system will automatically determine the connection, but the modem mode will have to be turned on manually in the corresponding menu. The computer recognizes the device as a new network card and will try to get it. IP-address.
The advantages of wired connectivity are obvious: the smartphone does not discharge, but instead charges from a USB port. In addition, data transfer speeds are limited only by the capabilities of the cable and USB standard, not by the range of Wi-Fi. This is ideal for stationary work in places with poor wireless reception.
However, there are some nuances to be aware of: some enterprise computers may block the installation of drivers for new network devices, which may require installing Xiaomi USB Driver drivers or changing the system security settings.
⚠️ Warning: When connecting to public computers (libraries, internet cafes) avoid mode USB-modem, as this creates a direct communication channel between devices, which may not be secure.
If your computer can’t see the Internet after you turn on the function, try changing it. USB-The problem is often the damage to the wires of the cables that are responsible for the transmission of data, even if the charging is normal.
Bluetooth Panorama: Saving Energy
A third, less popular but energy-efficient way to distribute the Internet is Bluetooth panorama, which is relevant in situations where the Xiaomi Redmi battery is critically low and access to the network is urgent. Data transfer speeds are much lower than over Wi-Fi, but this is enough to send mail or messengers.
The setup process requires pairing both devices. First, you need to turn on Bluetooth on your smartphone and on the receiving device, perform (pairing), and then activate the “Bluetooth modem” function in the settings menu. On the client side, you will also need to choose a network connection via Bluetooth.
The main advantage of this method is the minimum power consumption of the radio module. Bluetooth Low Energy technology allows the smartphone to work in the distribution mode much longer than with active Wi-Fi radiation, which makes the method ideal for emergency situations on the road.
It is worth noting that connection speeds rarely exceed 1-2 Mbps, which is not enough to watch high-resolution video. Delays (ping) can also be high, making it impossible to use VoIP telephony or online games.
Why does the Bluetooth modem work slower?
Comparison of Internet Distribution Methods
To choose the best option for your situation, you need to clearly understand the differences between the three methods described. Each of them has its own niche application, and there is no universal solution for all cases. Below is a comparison table that will help you navigate the characteristics.
| Parameter | Wi-Fi hotspot | USB modem | Bluetooth |
|---|---|---|---|
| Maximum speed | High (up to 400+ Mbps) | Very high (depends on cable) | Low (up to 2 Mbps) |
| Battery consumption | High-pitched | Charging the device | Minimum |
| Stability | Medium (depending on interference) | Maximum | Low. |
| Number of clients | Up to 10 devices | 1 | 1-2 |
As can be seen from the table, Wi-Fi wins in versatility and the ability to connect many gadgets. USB-Connectivity is the undisputed leader in stability and no impact on battery power. Bluetooth occupies the energy-saving niche, sacrificing speed for battery life.
You also need to consider the type of task you want to see. 4K-If you want to download heavy files to a PC, you'll need to use cable, but if you just need to send a text message or coordinates in a navigator, Bluetooth is the smartest choice.
Security issues and operator restrictions
Tethering carries certain risks that you can’t forget: By opening up your network, you potentially allow other devices to see your traffic unless you use additional security, which is why setting a strong password and using WPA3 (or at least WPA2) encryption protocol are mandatory.
Cellular operators often implement Internet distribution detection systems (DPI). They're analyzing. TTL-requests and other package settings to determine that the Internet is not being used on the smartphone itself, but on a third-party device, and in response, the operator can either block the connection or charge an additional fee.
- 🔒 Encrypting traffic – use it VPN on a smartphone to hide the nature of the data transmitted from the provider.
- 👀 Connection monitoring – check the list of connected devices in the Xiaomi Redmi access point menu regularly.
- ⚙️ Change of change TTL — Advanced users can change the meaning TTL in system files to hide the fact of distribution (root access is required).
Xiaomi Redmi owners should be careful when connecting to unknown devices. Attackers can try to inject malicious code or intercept a session if the device automatically accepts connections without confirmation. Always require proof of pairing.
💡
For maximum security, change the password from the hotspot each time you give the internet to strangers, and turn off the network visibility feature (hidden SSID) if you only connect your devices.
Optimization and extension of battery life
Internet is one of the most energy-intensive things in a smartphone, the radio is powered up, the processor processes packets, and the screen, if it's on, also consumes power. To keep Xiaomi Redmi from running out at the worst possible time, you should use built-in optimization tools.
The MIUI hotspot settings have a feature called "Switch off the hotspot automatically," which allows you to set a timer or condition by the number of connected devices that will stop giving the Internet, which saves the battery if you forgot to turn off the feature after use.
It is also recommended to reduce the brightness of the screen or turn it off altogether, since in modem modem the screen is not needed. AMOLED-Xiaomi also slightly reduces power consumption when actively using the settings menu.Switching off background apps on the smartphone itself will free up the processor resources.
⚠️ Warning: Do not cover your modem smartphone with a blanket or pillow. Active heat generation in a confined space can cause overheating and emergency shutdown of communication modules.
If you're planning a long Internet session, it's best to keep your smartphone connected to an external battery (Power Bank), which compensates for the high energy consumption and allows you to work for hours without interruption. Tethering, in conjunction with Power Bank, turns your smartphone into a full-fledged mobile router.
💡
Proper setting of auto-disconnect timers and the use of external power is the key to long-term and safe operation of the smartphone in modem mode.
