Android Wi-Fi Keeps Disconnecting (Simple Fixes That Work)

If your Android phone keeps disconnecting from Wi-Fi, it usually happens because of wrong settings, weak signals, software glitches, or router issues. Follow the steps below to fix it quickly.

1. Restart Wi-Fi and Your Phone

A simple restart can fix temporary network glitches.

  • Turn off Wi-Fi.
  • Restart your phone.
  • Turn Wi-Fi back on and reconnect.

2. Forget the Wi-Fi Network and Reconnect

Saved Wi-Fi settings may get corrupted after updates.

  • Go to Settings → Wi-Fi
  • Tap your Wi-Fi name
  • Select Forget
  • Reconnect with your password

3. Turn Off Battery Saver Mode

Battery saver can disconnect Wi-Fi to save power.

  • Go to Settings → Battery
  • Turn off Battery Saver / Power Saving Mode

4. Disable Adaptive Wi-Fi or Network Switching

Some phones switch to mobile data automatically.

  • Go to Settings → Wi-Fi
  • Turn off features like Wi-Fi+, Adaptive Wi-Fi, Intelligent Network Switching, or Switch to Mobile Data

5. Reset Network Settings

This resets Wi-Fi, mobile data, and Bluetooth settings (no data loss).

  • Go to Settings → System → Reset Options
  • Tap Reset Network Settings
  • Confirm the reset

6. Check Your Router

Your router may be causing the disconnections.

  • Restart the router
  • Move closer to the router
  • Connect another device to test
  • Switch to 2.4GHz for more stable signal
  • Update router firmware if available

7. Turn Off VPN

VPNs can interrupt Wi-Fi stability.

  • Go to Settings → Network & Internet → VPN
  • Turn off VPN

8. Update Your Android Software

  • Go to Settings → System → System Update
  • Install available updates

9. Remove Problematic Apps

Cleaning or battery-saving apps sometimes disconnect Wi-Fi.

If you use any of these apps, try removing them:

  • Clean Master
  • DU Cleaner
  • Battery Saver apps
  • Heavy security apps

10. Factory Reset (Last Option)

Only do this if nothing else works.

  • Back up your data
  • Go to Settings → System → Reset Options
  • Select Erase all data (factory reset)

When to Seek Repair

If Wi-Fi still disconnects, there may be hardware problems like a damaged Wi-Fi antenna or internal board issue. Visit an authorized service center for a hardware check.
