How to Fix Android WiFi not Turning on

To fix Android Wi-Fi not turning on, follow these troubleshooting steps:

1. Restart Device: Power off and then turn on your Android device.

2. Toggle Airplane Mode: Enable Airplane Mode for 10 seconds, then disable it. Check Wi-Fi connection afterward.

3. Check Settings: Ensure Airplane Mode is turned off, Auto-Reconnect is enabled for the network, and Parental Controls or Location Services settings aren't restricting Wi-Fi usage.

4. Reset Network Settings: Go to Settings > System > Advanced > Reset Options > Reset Wi-Fi, Mobile & Bluetooth. This will reset network settings without affecting user data.

5. Forget Wi-Fi Network: Forget the problematic Wi-Fi network, restart your device, and then reconnect to the network by entering the password.

6. Check Router: Ensure your router is functioning properly. Unplug it for 30 seconds, then plug it back in and wait for all lights to come back on.

7. Update Android: Check for and install any pending Android updates, as these may contain Wi-Fi-related fixes.

8. Wipe Cache Partition: Boot into Recovery Mode and wipe the cache partition. This can be done by holding specific buttons during the boot process, which varies by device.

9. Factory Reset: If none of the above steps work, consider performing a factory reset as a last resort. This will erase all user data, so be sure to back up important information.

If the issue persists after trying these steps, it may be a hardware problem, such as a faulty Wi-Fi module or Bluetooth/Wi-Fi IC, which might require professional repair or device replacement.
