How to set up the Internet on Xiaomi Poco X3: from Wi-Fi to 4G/5G

Xiaomi Poco X3 remains a popular choice among users who value performance and functionality at an affordable price, but even with such a device, it can be difficult to set up the Internet β€” whether it is connecting to Wi-Fi, activating mobile data or solving problems with slow speed.

The Poco X3 features support for dual 4G (Dual VoLTE) and 5G capabilities in the Poco X3 Pro/GT. But even if your model is limited to 4G, the right network configuration can significantly improve communication quality. We will look at official ways of configuring through the phone menu, as well as alternative methods for cases where standard solutions do not work.

1. Wi-Fi Connection: Basic Setup and Problem Solving

The first thing you start with is connecting to a wireless network, and on the Poco X3, you do it through a standard menu, but there are a few things you should know about:

  • πŸ“Ά Automatic connection: The phone remembers the networks you previously connected to (SSID It is not broadcast, it must be added manually.
  • πŸ”’ Type of security: modern routers use WPA3, Poco X3 older versions MIUI You may not be able to support it. WPA2-PSK.
  • πŸ“‘ Ranges 2.4/5 GHz: If the router broadcasts in two bands, select 5 GHz for a higher speed (but shorter range) or 2.4 GHz for better stability in remote rooms.

To connect to Wi-Fi:

  1. Open the Settings. β†’ Wi-Fi.
  2. Activate the Wi-Fi switch (if it is turned off).
  3. Select your network from the list and enter your password.
  4. Press Connect.

⚠️ Note: If the network is not displayed, check if the router is enabled broadcast SSID. On some Poco firmware X3 may not show networks with Cyrillic characters in the name - rename the network to Latin.

Even with the right settings, the Poco X3 may be slower than expected, due to MIUI firmware, background processes or operator limitations.

  • πŸš€ Disabling background activity: go to Settings β†’ Annexes β†’ Manage applications and limit background work for unnecessary programs.
  • πŸ“Š Speed test: Use applications like Speedtest or nPerf to test the actual speed. Compare the results to your carrier's rate.
  • πŸ”„ Network Reset: If the speed drops for no reason, reset the settings via Settings β†’ System system β†’ Resetting settings β†’ Resetting network settings.

Poco X3 with MIUI 12.5+ firmware has a hidden feature called β€œHigh Speed LTE Mode” that forcibly uses all available 4G frequencies. To activate it, type ##4636### in the Phone app β†’ Select Phone Information β†’ Set your preferred network type β†’ LTE only.

If you are using dualities SIM-Remember that only one of them can work in the 4G-- I'm going to change the priority:

  • πŸ”Œ USB-Modem: Suitable for PC, provides stable connection and charges phone.
  • πŸ“Ά Bluetooth modem: slower Wi-Fi, but more energy efficient.

To set up the distribution:

  1. Go to Settings β†’ Connections and Sharing β†’ Modem Modem.
  2. Select the Dispensing Type (Wi-Fi Access Point, USB-modem).
  3. For Wi-Fi, set up a network name (SSID) and password (minimum 8 characters).
  4. Activate the Wi-Fi Access Point switch.

If your devices are not connected to your access point:

  • Check that the phone is on mobile Internet.
  • Make sure that the number of connected devices does not exceed the limit (usually 8-10).
  • Try changing the frequency range to 2.4 GHz (in the access point settings) if the connected device does not support 5 GHz.

πŸ’‘

When you distribute internet via USB, your phone may not charge from some laptops. Use the original cable or connect the charger in parallel.

  2. Select your APN and in the APN Type field add,ipv4 at the end (e.g. default,supl,ipv4).
  3. Save and restart the phone.

⚠️ Warning: Changing the settings of the engineering menu can disrupt the network. If the Internet is lost after the experiments, reset the network settings or return the modem settings to the default values.

7. Alternative ways of connecting to the Internet

If standard methods don’t work, consider alternatives:

  • πŸ“‘ USB-Tethering from another device: connect Poco X3 down USB to another phone or PC with the Internet and turn on modem modem on the main device.
  • πŸ”„ Bluetooth tetering: similarly USB, It's going to be slower, but it's going to be enough for messengers.
  • 🌍 Public Wi-Fi: Use applications like WiFi Map to find the nearest open network (but be careful with security!).
  • πŸ“Ά Outside 4G-Modem: If the operator signal is weak, connect the phone to an external modem via Wi-Fi.

For USB-tetering:

  1. Get Poco on. X3 to another device through USB-cable.
  2. On the main device (for example, laptop) turn on modem modem.
