How to Enable a Modem on Xiaomi: A Detailed Guide

Modern smartphones brand Xiaomi has long ceased to be just devices for calls, turning into full-fledged multimedia centers and working tools. One of the key features that ensure mobility and constant access to the Internet is the ability to use the phone as a mobile phone. USB-This is especially true in situations where wired connection is not available and mobile speed is not available. 4G or 5G Users often face the need to distribute the Internet to a laptop or desktop computer, but standard system settings do not always work out of the box as expected.

Enabling modem modem on shell devices MIUI HyperOS may require a number of additional actions hidden in the depths of the engineering menu or requiring activation through debugging. USB. USB-The modem allows not only to share traffic, but also to charge the device at the same time, which distinguishes this method from the usual distribution over Wi-Fi, which quickly lands the battery. In this article, we will discuss in detail all known ways to activate the function, ranging from standard settings to advanced methods for experienced users.

Understanding the network interfaces in Android is essential to successfully solve connectivity problems. If you plan to use your smartphone as a network adapter for your PC, it’s important to consider the drivers and operating system versions. We’ll look at the nuances of working with Xiaomi Redmi and Poco, where software can have unique limitations. Prepare for some steps to require care, but the result of a stable high-speed connection is worth it.

Standard activation of the Wi-Fi access point

The most obvious and often used way to turn a smartphone into a router is through the built-in function of the access point. USB-It doesn't require cables or drivers, but it's worth remembering that the Wi-Fi module consumes much more power, and the phone can get a lot of heat when you're working under load. To activate, you need to go to the settings, where network management is made in a separate block.

The MIUI interface may vary depending on the version, but the logic remains the same. You need to find the partition that connects and shares data. Here are the main switches that allow you to start the router mode. The system automatically creates a network with a name that contains the model of your device, for example, Redmi Note 12, and protects it with a password that can be changed for increased security.

• 📱 Open the Settings app and find the Connection and Sharing section or Wi-Fi Access Point".
• 🔌 Activate the Wi-Fi Access Point slider and configure the network name if necessary (SSID) and complex password.
• ⚙️ In advanced settings, select the security standard WPA3-Personal Maximum protection of transmitted data.
• 📶 Make sure the frequency range is set to 5GHz if your devices support this standard for increased speeds.

⚠️ Note: When using a 5GHz access point, the signal range may be smaller than at 2.4GHz, but the data rate will be significantly higher.

It’s important to note that some carriers may block or restrict traffic if your plan doesn’t include this option.In such cases, mobile internet may stop working on connected devices even though the smartphone itself will open sites. Bypassing such restrictions often requires changing the APN setting, which we’ll talk about in the next sections.

Setting up USB-modem through the developer menu

Often users are faced with a situation when connecting a cable to a computer point"USB-The modem is gray or completely absent from the menu.This is not a defect of the device, but a feature of the Android architecture that hides this feature until the active feature is detected. USB-To unlock the ability to use the smartphone as a network card, you need to activate the hidden developer menu.

The first step is to enable USB debugging. Find the About Phone option in the settings and quickly press 7-10 times on the MIUI version or build number until you notice that you have become a developer. Then a new "Additional" or "Extended Settings" section will appear in the main settings menu, where the desired switch is hidden. Without debugging on USB, the system will not allow you to control port modes.

After activating the developer menu, connect the phone to your computer with a quality cable. Go to the Debugging section. USB" and find the switch"USB-Modem. Now it should be active. If you use Xiaomi Black Shark or game models, make sure that in game mode there is no restriction on background data transfer, which can block the network interface.

⚠️ Note: Use of the original cable is critical: Cheap "charging-only" cables have no data lines, and a computer won't see the phone as a network device.

You may need to install drivers on your computer. Usually Windows 10 and Windows 11 automatically find the software you need through the Update Center. If that doesn't happen, you may need to manually install ADB drivers or Xiaomi specific drivers. Once you successfully install a new network adapter in your Device Manager, you'll have a new network adapter that will go through the Internet.

Addressing the lack of a paragraph USB-modem

The situation where the menu item remains inactive even after connecting the cable and turning on debugging is quite common, this may be due to the fact that the phone has identified the connection as "Charge Only". USB. Pull the notification curtain after connecting the cable, click on the notification Charging through USB" and select the "File Transfer" mode, or"USB-modem" if such option is available immediately.

Another reason could be a software conflict or a temporary malfunction in the work of the network services of Android. Try to reboot both devices — and the smartphone and the computer. Sometimes it helps to reset the network settings on the phone, but remember that this action will remove saved passwords from Wi-Fi and settings Bluetooth devices. Xiaomi Mi and older models also relevant to check the cable for physical damage.

If standard methods don't work, you can use third-party applications like USB Tunnel or Easy Tether, which create a tunnel connection bypassing system constraints. However, they require the client part to be installed on the computer and may have speed limits in free versions. This is an extreme measure when the standard RNDIS or ECM protocol doesn't work properly.

APN Configuration to Bypass Operator Restrictions

Many mobile operators implement traffic signaling (TTL) systems by blocking Internet access for modem-connected devices. To circumvent this limitation, change the access point (APN) settings. TTL (Time To Live) tells the operator's network equipment how many "jumps" a packet can make. The default is 64 on the phone, and the default is 128 or 255 on the computer. The operator sees the difference and blocks the connection.

To change this setting on Xiaomi, you need to go to the mobile network settings, select your SIM-Map and find "Access Points (APN)". Click on the active access point (for example, the Internet or mts). In the menu that opens, scroll down to the "Type" field. APN" Or create a new access point. APN" Add the dial-up networking value to existing values, such as default,supl,dun.

A more advanced method involves changing the very value of TTL in system files, which requires Root rights. Without superuser rights, you can try to change the value in the "APN" field (dot name), adding special commands there if the provider allows, but this rarely works. New versions of Android 12/13/14 may appear in the APN menu a separate "TTL" field where you can immediately write a value of 65 (64+1) or 128 to match the traffic signature from the PC.

After making changes, be sure to turn on and off "Flight Reim" to restart the communication module and apply the new settings. USB-The modem of the computer did not work, try to clear the cache of the application "Settings" or reset the settings APN before the factory and repeat the data entry procedure.

Using Bluetooth modem as an alternative

When USB-The port is busy, and the Wi-Fi module is damaged or requires energy conservation, and a Bluetooth modem comes to the rescue, which provides the lowest data rate of any of the surveyed, but has low power consumption and stability of the connection over short distances. For older laptops without a Wi-Fi adapter, this may be the only way to access the network through a Xiaomi smartphone.

The setup process starts with pairing devices. Make sure Bluetooth is on both your phone and your computer. In the Bluetooth menu on your PC, select device search, find your Xiaomi and enter the confirmation code. After successfully pairing your phone in the Connection and Sharing section, activate the Bluetooth modem switch.

• 🔗 On your computer, go to Devices and Printers (or Bluetooth and Other Devices").
• 📱 Find your phone, right-click and select Connect via" →"Access point” (or similar point).
• 🌐 Wait for the network icon to appear in the tray, which will mean a successful installation PPP-linkage.

⚠️ Note: Bluetooth modem connection speeds rarely exceed 1-2 Mbit/s: This is enough for instant messengers and email, but not enough for watching high-resolution video.

It's worth noting that Android allows you to connect only one device to a Bluetooth modem at a time. If you need to distribute the Internet to multiple gadgets, this method will not work. In addition, the range is limited to 10 meters in line of sight, and the walls significantly weaken the signal. However, for Bluetooth DUN emergencies, the profile remains a reliable tool in the user's arsenal.
