Resolving the error message “Network connection failed. Please check your internet connection” can be straightforward if you follow these steps:

1. Check Device Connections: Ensure your device is correctly connected to the internet, either through Wi-Fi or Ethernet.
2. Restart Your Device: Sometimes, simply rebooting your device can resolve temporary glitches.
3. Power Cycle Your Router/Modem: Unplug your router and modem, wait 30 seconds, then plug them back in. Wait for them to fully reboot.
4. Check Other Devices: See if other devices in your home can connect to the internet. This can help identify if the issue is device-specific or network-wide.
5. Run Network Troubleshooter (Windows): Use the built-in network troubleshooter to diagnose and fix common issues.
6. Forget and Reconnect to Wi-Fi: On your device, forget the Wi-Fi network and reconnect by entering the password again.
7. Check for Service Outages: Visit your ISP’s website or contact them to see if there are any outages in your area.
8. Update Network Drivers (Windows): Ensure your network drivers are up to date by checking the Device Manager.
9. Reset Network Settings: On your device, reset network settings to default. This can fix various connectivity issues.
10. Use an Ethernet Connection: If possible, connect your device directly to the router via Ethernet. This can help determine if Wi-Fi is the problem.
11. Check Firewall Settings: Ensure your firewall or antivirus software isn’t blocking the connection.
12. Inspect Cables: Check all cables connected to your router and devices for any damage.
13. Factory Reset Your Router: As a last resort, factory reset your router to restore it to default settings. Be cautious, as this will erase custom configurations.

Following these steps can help you quickly identify and resolve the network connection error.
