Follow these essential steps to troubleshoot the “Error: Network connection failed. Please check your internet connection.” message:

1. Check Physical Connections: Ensure all cables are securely connected to your modem and router. Look for any frayed wires or loose connections.

2. Restart Your Devices: Power off your modem, router, and computer or device. Wait for about 30 seconds, then power them back on. This simple step can resolve many connectivity issues.

3. Verify Network Availability: Check if other devices can connect to the internet. If they can, the issue may be isolated to your device.

4. Forget and Reconnect to the Network: On your device, go to Wi-Fi settings, forget the current network, and reconnect by entering the password again.

5. Run Network Troubleshooter (Windows): If you’re on a Windows device, use the built-in network troubleshooter. Go to Settings > Network & Internet > Status > Network troubleshooter.

6. Update Network Drivers: Ensure your network adapter drivers are up to date. Go to Device Manager, find your network adapter, right-click, and select “Update driver.”

7. Reset Network Settings: If all else fails, you can reset your network settings. On Windows, go to Settings > Network & Internet > Status > Network reset. On mobile devices, look for similar options in the settings.

These steps will assist you in diagnosing and potentially resolving the connectivity problem you’re facing.
