Advanced Troubleshooting Techniques

• Network Settings Reset:
  • Navigate to Settings > System > Advanced > Reset options.
  • Select Reset Wi-Fi, mobile & Bluetooth.
  • Confirm and allow your device to reset network settings.
• Modify Wi-Fi Settings:
  • Disable any power-saving modes that may turn off Wi-Fi to save battery life.
  • Change Wi-Fi frequency band settings to avoid congestion:
    • Go to Settings > Wi-Fi > Advanced > Wi-Fi frequency band, and try selecting 5GHz or 2.4GHz manually.
• Update Device Software:
  • Check for and install any available Android updates: Settings > System > Advanced > System update.

Maintaining Stable Wi-Fi Connectivity

To maintain a stable Wi-Fi connection on your Android device, ensuring the proper placement of your Wi-Fi router is key. Place your router in a central location, away from physical obstructions and interference from household appliances like microwaves or cordless phones.

Keeping your router’s firmware updated is critical, as manufacturers often release updates to improve performance and security.

Regularly monitoring your Wi-Fi signal strength can help you identify areas in your home or office with weak coverage.
