Step 4: After completing the commands, restart your computer.

This will reset your network settings to their default configuration and can resolve many network connectivity issues.

6. Check for Hardware Issues:

If the above steps don't resolve the issue, the problem could be hardware-related. You can try these steps:

Step 1: If you're using a desktop PC, try reseating the Ethernet cable in both the router and your computer. Step 2: Try using a different Ethernet cable to rule out a defective cable. Step 3: Test the network adapter in another device or PC to check if it’s working.

If your RTL8211FS-CG chip or motherboard has suffered a physical failure, you may need to replace the damaged hardware.

7. Contact Support:

If none of the above solutions worked, it may be time to contact the device manufacturer’s support for further assistance. They may provide additional solutions, or it could indicate a need for hardware replacement.

Conclusion:

By following this step-by-step guide, you can troubleshoot and resolve RTL8211FS-CG chip failures in Windows 10. Start by checking the driver and network settings, and if those don’t resolve the issue, move on to more advanced solutions like hardware checks or resetting network configurations.
