How to Troubleshoot and Fix Common WiFi Connection Issues on Android

  • Restart your Android device and router to clear any temporary glitches
  • Forget the WiFi network and reconnect to refresh the connection
  • Check for any software updates for your device and router firmware
  • Disable battery optimization and WiFi sleep policies for better connectivity
  • Reset network settings or perform a factory reset as a last resort

WiFi connectivity issues on Android devices can be frustrating, but they are often fixable with some troubleshooting steps. In this article, we’ll explore various methods to resolve common WiFi problems on your Android smartphone or tablet.

Restart Your Device and Router

The first and simplest step is to restart your Android device and your WiFi router. This can help clear any temporary glitches or conflicts that may be causing the WiFi connection issues.

  1. Restart your Android device: Press and hold the power button, then select “Restart” or “Reboot” from the options.
  2. Restart your WiFi router: Unplug the power cable from your router, wait for about 30 seconds, and then plug it back in.

After the restart, try reconnecting to your WiFi network and see if the issue is resolved.

Forget and Reconnect to the WiFi Network

Sometimes, the WiFi connection can become unstable due to cached data or incorrect settings. In such cases, forgetting the WiFi network and reconnecting can help establish a fresh connection.

  1. Go to your Android device’s Settings > WiFi.
  2. Tap on the WiFi network you’re connected to and select “Forget” or “Forget network”.
  3. Once the network is forgotten, toggle the WiFi off and back on.
  4. Your device will now scan for available networks. Select your WiFi network and enter the password to reconnect.

Check for Software Updates

Outdated software on your Android device or WiFi router can sometimes cause compatibility issues or bugs that affect WiFi connectivity. It’s always a good idea to keep your device and router firmware up to date.

  1. Check for Android updates: Go to Settings > System > System update (or Software update) and tap “Check for updates”. If an update is available, follow the on-screen instructions to download and install it.
  2. Check for router firmware updates: Consult your router manufacturer’s website or user manual for instructions on how to check for and install firmware updates for your specific router model.

Disable Battery Optimization and WiFi Sleep Policies

Some Android devices have battery optimization features and WiFi sleep policies that can interfere with WiFi connectivity. Disabling these settings can help maintain a stable WiFi connection.

  1. Go to Settings > Apps (or Apps & notifications) > Special app access > Battery optimization.
  2. Find and tap on your WiFi app (e.g., Google Play Services) and select “Don’t optimize” or “Not optimized”.
  3. Additionally, you can go to Settings > Developer options (if not available, you may need to enable it first) and disable “WiFi sleep policy”.

Reset Network Settings or Factory Reset

If none of the above steps work, you may need to reset your Android device’s network settings or perform a factory reset as a last resort.

Reset Network Settings:

  1. Go to Settings > System > Reset options > Reset WiFi, mobile & Bluetooth.
  2. Confirm the reset by tapping “Reset settings”.

This will reset all network settings, including WiFi passwords, Bluetooth pairings, and VPN configurations.

Factory Reset:

A factory reset will erase all data, settings, and apps from your Android device, restoring it to its original state. This should only be done if the WiFi issue persists after trying all other troubleshooting steps.

  1. Go to Settings > System > Reset options > Erase all data (factory reset).
  2. Follow the on-screen instructions to back up your data and confirm the reset.

After the factory reset, you’ll need to set up your device again and reconnect to your WiFi network.


Why does my Android device keep disconnecting from WiFi?

There could be several reasons why your Android device keeps disconnecting from WiFi, such as:

  • Interference: Other devices or appliances operating on the same frequency can cause interference and disrupt the WiFi signal.
  • Range: If you’re too far away from the router, the WiFi signal may be too weak to maintain a stable connection.
  • Router issues: Problems with your router’s firmware, settings, or hardware can cause frequent disconnections.
  • Battery optimization: Aggressive battery optimization settings on your Android device may be causing the WiFi to disconnect when the device is idle or in sleep mode.

How can I improve my Android device’s WiFi signal strength?

To improve your Android device’s WiFi signal strength, you can try the following:

  • Move closer to the router: Reduce the distance between your device and the router to get a stronger signal.
  • Change the router’s position: Move the router to a more central location or away from obstructions like walls or appliances.
  • Update router firmware: Check for and install any available firmware updates for your router, as they may include improvements for signal strength and range.
  • Use a WiFi extender or repeater: If your home or office has a large area, consider using a WiFi extender or repeater to boost the signal in areas with poor coverage.

Why is my Android device not detecting any WiFi networks?

If your Android device is not detecting any WiFi networks, try the following:

  • Toggle WiFi on and off: Go to Settings > WiFi and turn the WiFi off, wait a few seconds, and then turn it back on.
  • Restart your device: Perform a full restart of your Android device, as this can sometimes resolve temporary glitches or conflicts.
  • Check for hardware issues: If the issue persists, there may be a hardware problem with your device’s WiFi antenna or module, in which case you may need to seek professional repair or replacement.

By following these troubleshooting steps, you should be able to resolve most common WiFi connection issues on your Android device. However, if the problem persists, it’s recommended to seek further assistance from your device manufacturer or a professional technician.
