How to Fix Wi-Fi Disconnection Issues on Xiaomi Phones (MIUI Guide)

 Introduction

One of the most common problems Xiaomi smartphone users face is Wi-Fi disconnecting automatically. This frustrating issue can interrupt work, streaming, or downloads, and in most cases, it’s caused by MIUI’s network settings rather than hardware failure.

If you own a Xiaomi, Redmi, or POCO device and notice your phone sometimes disconnects from Wi-Fi without warning, this guide will help you fix the issue and maintain a stable connection.

Why Xiaomi Phones Disconnect from Wi-Fi Automatically

In many cases, Wi-Fi disconnection problems are linked to MIUI’s automatic network switching feature. This function is designed to connect your phone to the network with the strongest signal. However, it can mistakenly drop a stable Wi-Fi connection, switching to mobile data even when the Wi-Fi is sufficient.

Other causes may include:

  • Misconfigured Wi-Fi settings

  • Third-party apps interfering with network connections

  • Outdated system software

Step-by-Step Solution: Disable Automatic Network Switching

To prevent your Xiaomi phone from disconnecting from Wi-Fi automatically, follow these steps:

Step 1: Open Wi-Fi Settings

  • Go to Settings → Wi-Fi.

Step 2: Access Wi-Fi Assistant

  • Scroll down and tap on Wi-Fi Assistant.

Step 3: Disable “Switch to Better Network Automatically”

  • Find the option “Select the best network automatically” and toggle it off.

This simple adjustment ensures your Xiaomi phone remains connected to the chosen Wi-Fi network instead of switching to mobile data or another network when the signal fluctuates.

Additional Tips if Wi-Fi Still Disconnects

If disabling automatic network switching doesn’t completely solve the problem, try the following:

  1. Check for Misconfigured Settings:

    • Review any custom Wi-Fi settings or network priorities you may have adjusted.

  2. Check Installed Apps:

    • Some apps, particularly VPNs or network management tools, may interfere with Wi-Fi. Try uninstalling or disabling them temporarily.

  3. Restart Your Router:

    • Sometimes the issue is caused by the router rather than the phone. Restarting your router can resolve connectivity drops.

  4. Reset Network Settings:

    • Go to Settings → Additional settings → Backup & Reset → Reset Network Settings to restore Wi-Fi, Bluetooth, and mobile data settings to default.

  5. Factory Reset (Last Resort):

    • If none of the above works, consider a factory reset. Make sure to back up your data first.

    • Go to Settings → About Phone → Factory Reset. This will restore your device to default MIUI settings and remove any misconfigurations causing Wi-Fi disconnections.

Conclusion

Wi-Fi disconnection issues on Xiaomi, Redmi, and POCO phones are usually caused by MIUI’s automatic network switching or misconfigured settings. By following the steps above — disabling automatic network selection, reviewing apps and settings, and, if necessary, resetting your network or performing a factory reset — you can maintain a stable Wi-Fi connection and avoid frequent interruptions.

Staying connected has never been easier with these MIUI tips, ensuring your Xiaomi phone delivers reliable performance for work, streaming, and daily use.
