Here’s a straightforward guide to troubleshoot the “Error: Network connection failed. Please check your internet connection” message:

1. Restart Your Device: Turn off your computer or device and turn it back on. This can often resolve minor software glitches.
2. Check Your Cables: Ensure that all cables connected to your router and modem are secure. Look for any signs of wear or damage.
3. Reboot the Router: Unplug your router from the power source, wait for 30 seconds, and plug it back in. Wait for it to fully restart.
4. Check for Outages: Visit your ISP’s website or contact them to see if there are any service outages in your area.
5. Forget and Reconnect to Wi-Fi: On your device, go to Wi-Fi settings, forget the network, and reconnect by entering the password.
6. Update Network Drivers: Ensure that your network drivers are up-to-date. You can usually find this in the settings menu of your device.
7. Run the Network Troubleshooter: On Windows, use the built-in network troubleshooter to automatically find and fix network problems.
8. Check Firewall Settings: Sometimes, firewalls can block your internet connection. Check your firewall settings to ensure they are not overly restrictive.
9. Reset Network Settings: If all else fails, you can reset your network settings. This will erase all saved Wi-Fi passwords, so proceed with caution.
10. Contact Your ISP: If the issue persists, reach out to your ISP for assistance. They may be able to identify problems on their end.

These steps will guide you in resolving the network connection error efficiently.
