How to Fix Wi-Fi Connection Issues on Sony KD-43X75WL TV

Initial Wi-Fi Troubleshooting Steps

• 💡 Verify router functionality by checking if other devices on the same network, like a smartphone, can access online applications.
• ⚠️ Minimize wireless interference by moving potential sources like phones, gaming consoles, or Bluetooth speakers away from the TV.

Soft Reset and Network Reconnection

• ⚡ Perform a soft reset by holding the TV's power button until it turns off, then unplugging it from the power source for 5 minutes.
• 🔌 After plugging the TV back in and letting it fully restart, navigate to Settings → Network & Internet.
• 🔄 If the Wi-Fi still doesn't connect, select 'Forget Network' for your Wi-Fi, then try reconnecting by entering the password again.

Testing with Alternative Networks

• 📱 Connect the TV to a mobile hotspot from your smartphone to test connectivity.
• 📶 For mobile hotspots, ensure settings are configured for both 2.4GHz and 5GHz compatibility and verify the password.

Diagnosing and Factory Reset

• 🛠️ If the TV connects to a mobile hotspot but not the router, the issue might be router compatibility.
• ⚠️ If the TV fails to connect to any network, including a mobile hotspot, it may indicate a hardware issue.
• 💾 As a last resort, consider a factory data reset via the System menu, but ensure to back up all data first, as this will erase all settings and accounts.
