Distributing the Internet from Xiaomi to a computer via Bluetooth

In situations where the Wi-Fi router is not available, USB-The cable is lost or not working, Bluetooth technology comes to the rescue. Xiaomi smartphone owners often use them as modems, but not everyone knows about the possibility of creating a Bluetooth boardnet to transfer traffic to a laptop or desktop PC. This method is especially relevant for older computers without Wi-Fi modules or in cases where you want to minimize the power consumption of a smartphone.

Although the speed of connection via Bluetooth modem is significantly inferior to modern Wi-Fi standards, the stability and versatility of this protocol make it an indispensable tool in the arsenal of any user. The process of setting up on devices with a shell MIUI or HyperOS has its nuances, which we will discuss in detail.

Unlike fast but energy-intensive Wi-Fi, a Bluetooth connection consumes significantly less battery power, which is critical for long trips or business trips when it counts for minutes of battery life. Next, we’ll look at a step-by-step algorithm that will turn your phone into a reliable source of Internet.

Benefits and Limitations of Bluetooth Modem on Xiaomi

Using a Xiaomi smartphone as a Bluetooth modem has a number of undeniable advantages, the main of which is compatibility. Virtually any laptop released in the past 15 years has a Bluetooth module, while Wi-Fi adapters may be missing or faulty. In addition, the range and penetration of the signal here are less critical, since devices are usually in close proximity to each other.

But it's a realistic assessment of the technical capabilities. The bandwidth of the channel is limited by the Bluetooth standard. If your phone supports Bluetooth 5.0 and your computer only 4.0, the speed will be limited to the older version. The maximum theoretical speed is rarely more than 2-3 Mbps, which is enough for instant messengers, mail and navigation, but not enough for streaming video.

⚠️ Attention: When using a Bluetooth modem actively, the smartphone can heat up less than when operating in Wi-Fi access point mode, but constant data transfer still puts a strain on the power controller.

Connectivity stability is also important: the protocol is less susceptible to external interference from microwave ovens or neighbor routers, which often happens in the 2.4 GHz band. This makes Xiaomi’s Bluetooth modem a predictable tool for working with text data and light web pages in noisy air conditions.

Preparation of Xiaomi smartphone to work in modem

Before you start setting up, you need to make sure that your Xiaomi device has the basic data functions enabled. Unlike some other brands, the MIUI interface bogs down some settings deeper into the menu, so it’s important to consistently check all settings. The first step should always be to enable mobile data, as this channel will be broadcast on the PC.

Go to the settings and find the connection section. Depending on the shell version (MIUI 12, 13, 14 or the new HyperOS), the path may be slightly different, but the logic remains the same. You need to activate the device's visibility for external gadgets, otherwise the computer will not detect the phone when scanning.

• 📱 Make sure that SIM-The card is active and has a positive balance or connected tariff with the Internet.
• 🔋 Charge your smartphone to a minimum 40-50%, Internet use is slower than Wi-Fi, but it consumes more energy.
• 👁️ Turn on Bluetooth visibility in the settings so that the PC can find the device to pair.

Special attention should be paid to operating system versions. Older versions of Android or MIUI may have encountered bugs in the Bluetooth stack that were patched in security updates. Check for updates in Settings → About Phone → MIUI version to rule out software failures.

Step-by-step: activation of modem modem

After the preparatory phase, we move on to the direct activation of the function. In the shell of Xiaomi, this switch is located in the menu of access points. Navigating the menu requires care, since the item can be called differently depending on the localization of the system.

Open the settings and go to Access Point and modem. Here you'll see some options: Wi-Fi hotspot, USB-We need a third option, move the slider to the active position, and the system can warn you that Bluetooth will be turned on forcefully if it was turned off, confirm the action.

Settings → Connections and Sharing → Access Point and Modem → Bluetooth modem

It's important to understand the difference between simply turning on Bluetooth and activating modem modem. Even if the devices are paired, the Internet won't go until you switch a special switchboard in the settings menu, and it's done for safety, so you don't accidentally start to waste traffic.

⚠️ Note: Once the Bluetooth modem is turned on, Xiaomi can automatically turn off the Wi-Fi distribution if it was active.

Now your smartphone is ready to receive a connection request. It will appear on the list of available devices as a network source, but only after successfully pairing with the computer. Remember that the device name in Bluetooth should be clear so that you do not confuse it with the neighboring gadgets.

Combination of the computer and smartphone Xiaomi

The next step is on the computer side, and regardless of the operating system (Windows 10, 11, or Linux), the algorithm is similar, so you have to find the device on the list of available devices and do pairing, and the key here is to check the confirmation code that will appear on both screens.

In Windows 10 and 11, open the settings through the Start menu and select Devices or Bluetooth and Devices. Click Add Bluetooth or other device. The list should show your Xiaomi (or the name you gave it). Click on it and check the numerical code.

Once paired successfully, the device will change its status to Connected, but that doesn't mean that it has the Internet, the computer sees the phone as a headset or input device, but not as a network adapter. It often requires an additional step in the control panel to activate the data transfer.

• 💻 Open the Control Panel" →"Devices and Printers (Relevant for Windows 10).
• 📱 Find your phone icon, right-click and select Connect via" →"Access Point (Internet)
• 🔄 Wait for the network icon to appear in tray instead of the standard Bluetooth icon.

In some cases, Windows can automatically determine the type of network and start the Internet without manual intervention through the control panel. If this does not happen, check the Device Manager. In the "Network adapters" section, a new device called Bluetooth Network Connection should appear.

Set up a network connection in Windows

If the automatic setup doesn’t work, you’ll have to manually tell the system that the Bluetooth channel should be used to access the network. In modern versions of Windows 10 and 11, this happens almost unnoticed, but in corporate networks or on older OS builds, manual edits may be required.

Go to Network and Internet Options and select Adapter Settings. Here you will see a list of all network interfaces. Find a connection marked as Bluetooth Network Connection. If it is disabled (gray icon), right-click and select "Enable".

Sometimes the system may try to use this connection as the main network, even if the Internet is not through it (for example, if the phone lost the 4G signal), in which case, in the adapter properties, you can uncheck the IPv6 protocol or change the interface label to prioritize other connections.

⚠️ Note: When connected via Bluetooth, Windows can define the network as "Public." This is the right choice from a security perspective, but it can block some local services. If you need access to a printer on the network, change your profile to "Private".

Checking the health is done by simply opening the browser, and if pages load slowly, that's OK for this type of connection, but as long as there are no DNS errors, if the Internet doesn't work, try turning off and re-enable the Bluetooth modem in your phone's settings.

💡

To speed up the work of web pages through a Bluetooth modem, turn on the "Traffic Saving" mode in the browser or use text versions of sites. This will reduce the load on a narrow communication channel.

Problem Solving and Diagnostics

Despite the simplicity of the technology, users often face difficulties, and the most common problem is that devices mate, but the Internet does not appear. DNS-And then you can use a static registration. DNS (For example, from Google: 8.8.8.8) in the protocol properties IPv4 computer-based.

Another common situation is a communication breakdown at short intervals, which can be caused by the power saving of the Bluetooth adapter itself in your laptop. Go to Device Manager, find your Bluetooth module, open properties, and in the Power Management tab, uncheck the checkmark for permission to turn off the device.

If Xiaomi isn’t visible to the computer at all, make sure the phone isn’t in “Invisible” mode and you’re in the process of finding devices, sometimes by cleaning up the list of old pairings on both devices and creating a new pair from scratch.

• 🔄 Rebooting both devices often solves 90% of communication protocol problems.
• 📶 Make sure the phone is not on flight mode and the icon is on. 4G/LTE.
• 🛡️ Antivirus on PC can block new network connection – check the security logs.

In rare cases, the problem lies in the Bluetooth drivers on the computer. Outdated drivers may not support the PAN (Personal Area Network) profile necessary for the distribution of the Internet. Updating drivers from the website of the laptop manufacturer or adapter can fix the situation.

💡

The main reason for the unstable work is outdated Bluetooth drivers on the PC or aggressive energy saving, which breaks the connection into simplicity.
