Why Xiaomi Wi-Fi Disconnects Happen

Wi-Fi disconnections on Xiaomi devices can occur due to several reasons:

  • Software bugs in MIUI updates

  • Incorrect network settings

  • Router compatibility issues

  • Battery optimization settings interfering with network connections

  • Weak Wi-Fi signals

Identifying the cause is the first step toward resolving the problem.

Step 1: Restart Your Xiaomi Device and Router

A simple restart often resolves temporary network glitches:

  1. Turn off your Xiaomi phone and power it back on after a few seconds.

  2. Restart your Wi-Fi router to refresh the network connection.

  3. Reconnect your phone to the Wi-Fi network.

This basic step can fix minor software or network conflicts causing frequent disconnects.

Step 2: Forget and Reconnect to Wi-Fi Network

Re-establishing the connection can solve authentication or IP address issues:

  1. Go to Settings → Wi-Fi.

  2. Tap the connected network and select Forget Network.

  3. Reconnect by entering your Wi-Fi password.

This ensures your phone establishes a fresh connection with proper configuration.

Step 3: Check MIUI Wi-Fi Settings

Xiaomi’s MIUI interface includes settings that may interfere with stable connections:

  • Navigate to Settings → Wi-Fi → Wi-Fi Preferences.

  • Turn off Smart Network Switch to prevent automatic switching between Wi-Fi and mobile data.

  • Disable Wi-Fi+ if your phone automatically connects to weak networks.

These adjustments help maintain a stable Wi-Fi connection without unnecessary interruptions.

Step 4: Disable Battery Optimization for Wi-Fi

Xiaomi devices aggressively optimize battery usage, which can disconnect Wi-Fi when the screen is off:

  1. Go to Settings → Battery & Performance.

  2. Tap Manage Apps Battery Usage → Select the Wi-Fi-dependent apps.

  3. Choose No Restrictions to prevent background disconnections.

This step ensures that critical apps maintain continuous internet access even in battery-saving mode.

Step 5: Update MIUI and Router Firmware

Outdated software can cause compatibility issues:

  • Go to Settings → About Phone → System Update and install any available updates.

  • Check your router manufacturer’s website for the latest firmware updates and follow instructions to upgrade.

Keeping both your Xiaomi device and router updated improves stability and fixes known Wi-Fi issues.

Step 6: Reset Network Settings

If Wi-Fi disconnects persist, resetting network settings may help:

  1. Go to Settings → Connection & Sharing → Reset Wi-Fi, Mobile Networks, and Bluetooth.

  2. Confirm the reset and reconnect to your Wi-Fi network.

This action clears corrupted configurations that may interfere with connectivity.

Frequent Wi-Fi disconnects on Xiaomi devices can disrupt productivity, but most issues are solvable with simple adjustments. By following AvNexo’ guide, you can maintain a stable and reliable Wi-Fi connection on your Xiaomi smartphone. Regular updates, proper configuration, and battery optimization settings play a key role in preventing interruptions and improving your overall user experience.
