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:

Turn off your Xiaomi phone and power it back on after a few seconds.
Restart your Wi-Fi router to refresh the network connection.
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:

Go to Settings → Wi-Fi.
Tap the connected network and select Forget Network.
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:

Go to Settings → Battery & Performance.
Tap Manage Apps Battery Usage → Select the Wi-Fi-dependent apps.
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Outdated software can cause compatibility issues: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:

Go to Settings → Connection & Sharing → Reset Wi-Fi, Mobile Networks, and Bluetooth.
Confirm the reset and reconnect to your Wi-Fi network.

This action clears corrupted configurations that may interfere with connectivity.

Final Thoughts

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.
