Why Xiaomi smartphone can replace the router for laptop
Modern smartphones Xiaomi on the basis MIUI They can provide mobile Internet as well as specialized 4G/5G-This solution helps when you don't have Wi-Fi and you need to work on your laptop urgently, and the main advantages of this approach are mobility (the Internet will be where the operator has coverage), no additional devices and the ability to flexibly control traffic through the phone settings.
Technologically, the distribution of the Internet with Xiaomi is implemented in three ways: through a Wi-Fi access point (the most popular option), by cable. USB-modem (to save battery power) and Bluetooth (if other methods are not available), each of them has its own nuances, such as, USB-Connectivity makes the connection more stable, but requires wires, and Wi-Fi hotspot is more convenient for multiple devices at once. MIUI 14/15 Android 13/14.
It is important to consider that the speed and stability of the connection depends not only on the Xiaomi model (for example, Redmi Note 12 Pro+ or POCO F5 support 5G), but also on the tariff of the mobile operator. Some tariffs limit the speed when you distribute the Internet or block this feature altogether โ check the conditions with your provider before setting up.
Preparing Xiaomi phone for the distribution of the Internet
Before you set up your internet distribution, make sure your Xiaomi is ready for the task.
- ๐ถ Mobile network: the phone must be active data transfer (icon) 4G/5G or LTE Check the balance and connection status in the operator's application.
- ๐ Battery charge: the Internet is actively used up. If the charge is below 30%, connect the phone to the charger or use it. USB-modem (it burns the battery less).
- ๐ Software updates: outdated version MIUI It can cause crashes. Update the system to Settings. โ The phone. โ Updating the system.
- ๐ก๏ธ Security: if the phone is installed VPN or firewall, temporarily disable them - they can block data transmission.
Pay special attention to mobile network settings, and in some regions, operators default to limit the speed at the handset (called tethering) to remove the restriction:
- Open the Settings. โ SIM-maps and mobile networks.
- Choose yours. SIM-map and go to the Access Point (APN).
- Click on the active APN profile and check the APN type parameter.Put the dun value through the comma (for example, if there was default,supl, make default,supl,dun).
- Save the changes and restart the phone.
โ ๏ธ Attention: Change APN If the Internet is lost after editing, return the original settings or contact the operator for support.
Method 1: Distributing the Internet through Wi-Fi hotspot
This is the most versatile method that works on all Xiaomi models โ from the budget Redmi A2 to the flagship Xiaomi 14 Ultra. Advantages: you can connect several devices at the same time (laptop, tablet, other phone), a range of up to 10 meters, high speed (up to 866 Mbps on Wi-Fi 6).
Instructions for setting:
- Open Settings โ Access Point and modem (on some firmware, the path may differ: Settings โ Connections โ Access Point).
- Activate the portable access point switch.
- Click Access Point Settings to Ask: ๐ Name of the network (SSID): Think of a unique name (for example, Xiaomi_Hotspot_123). ๐ Password: minimum 8 Use letters and numbers (for example, characters, MiHot5pot2026!). ๐ก Range: Choose 5 GHz for higher speed (if the laptop supports) or 2.4 GHz for better compatibility.
Save the settings and turn on the access point.
Now on the laptop:
- Open the list of available Wi-Fi networks (network icon in tree or Start โ Settings โ Network and Internet โ Wi-Fi).
- Select a network with your access point name, enter a password and connect.
| Parameter | Recommended value | Explanation |
|---|---|---|
| Security | WPA2-PSK or WPA3-PSK | WPA3 is more reliable, but not all devices support it. WPA2 is a universal option. |
| Frequency band | 5 GHz (priority) or 2.4 GHz | 5 GHz is faster but less range. 2.4 GHz is more stable over distance. |
| Auto-disconnection | Never in 10 minutes. | If you set "Never," the battery will run down faster. |
| Max. Connected devices | 5โ10 | The more devices, the lower the speed for each. |
โ ๏ธ Attention: Some tariffs block the distribution of Internet via hotspot (especially on unlimited rates).If after connecting the laptop shows "No Internet access", check the Internet. SMS from the operator or call in support. Alternatively, use USB-modem (modem).

Method 2: Connecting through USB-modem (most stable modem)
If you want maximum connection stability (for example, for video conferencing or online games), a USB modem is the best choice. This method also saves battery power from the phone, since the power comes from the laptop. Minus - requires a USB-Type C cable (or Micro-USB for older models).
Step-by-step:
- Connect your phone to your laptop with a cable. Use the original cable or a certified cable (cheap cables may not transmit data).
- On the phone in the notification menu, select the connection mode Data Transfer (or USB-The modem, if such an option appears automatically).
- If no automatic connection has occurred, go to Settings. โ Access Point and modem โ USB-modem and activate the switch.
- On your laptop, wait for the drivers to install (usually 10 to 30 seconds), and then a new connection (e.g., Ethernet or Ethernet) will appear in the list of network connections. USB-networker).
On Xiaomi models with Qualcomm processor (for example, POCO X5 Pro) USB-The modem can run faster than on phones with MediaTek chips (e.g. Redmi). 12C), If the speed is lower than expected, try to turn off. USB-debugging โ The phone. โ Version. MIUI (Click on version 7 times, then return to Additional โ For developers).

If the laptop does not see the phone USB-modem, try another port USB Or reboot both devices. Sometimes it helps to disable the charge optimization function in the Xiaomi battery settings.
Method 3: Internet distribution over Bluetooth (alternative)
It's less popular, but it's useful if you don't have cable and your phone's Wi-Fi isn't working, it's slower (up to 3 Mbps), but it's resistant to interference and saves battery life, and it's good for texting or mail, but not for streaming video.
How to set up:
- Turn on Bluetooth on your phone and laptop.
- On your phone, go to Settings โ Access Point and modem โ Bluetooth modem and activate the function.
- On your laptop, find the phone in the list of available Bluetooth devices and pair (a confirmation code may be required).
- After pairing in the Bluetooth laptop settings, select your Xiaomi and click Connect via โ Access Point.
Features of Bluetooth modem:
- ๐ Delays: Ping can reach 300โ500 ms (unsuitable for online gaming).
- ๐ Speed: maximum bandwidth โ about 3 Mbps (enough for messengers and mail).
- ๐ Energy consumption: battery consumption is lower than Wi-Fi, but higher than that of the USB.
โ ๏ธ Warning: Some Windows 11 laptops may lose the speaker sound after being connected via Bluetooth. To fix, go to Settings โ System system โ Sound and manually select the main audio device.

Solving common problems
Even with the right setup, you can have failures, and here are the typical situations and ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| The laptop connects to Wi-Fi, but the Internet does not work | Operator blocks distribution or incorrect APN settings | Check the APN (sign dun), reboot the phone or call the operator |
| USB-modem is not defined | Lack of drivers or faulty cable | Install Mi Phone Manager, try another cable or USB port |
| Bluetooth connection is constantly broken | Interference from other devices or an outdated version of Bluetooth | Disable other Bluetooth gadgets, update drivers on your laptop |
| Low Internet speed | Weak network signal or operator restriction | Move closer to the window, check the fare, try it. USB-modem |
If none of these methods work, reset the network settings on your phone:
- Go to Settings โ About the phone โ Reset settings.
- Select Network Reset (donโt reset all settings!).
- After restarting, repeat the handout setting.
For advanced users: If the problem is related to MIUI, you can try to turn on the developer mode and activate the debugging option over USB, and then enter in the laptop terminal:
adb shell settings put global tether_dun_required 0This command resets the requirement for APN dun, which sometimes helps bypass operator restrictions.
๐ก
If after all the manipulations the Internet on the laptop did not work, the problem may be in the operator's tariff. Call support and check if the distribution of Internet (tethering) on your tariff is allowed.
