Troubleshooting Ethernet Connectivity Issues on Windows 10: When Reinstalling the Network Adapter Doesn’t Help
Experiencing persistent internet connectivity problems can be a frustrating experience, especially when basic troubleshooting steps do not resolve the issue. If you’re facing a situation where your Windows 10 PC isn’t connecting to the internet despite an active Ethernet connection, and attempts to reinstall or reset network components have failed, you’re not alone.

Common Symptoms:
- Ethernet cable is connected physically but network status displays “No internet.”
- Network troubleshooter reports DNS server issues.
- Reinstalling the network adapter does not resolve the problem; in fact, the adapter may no longer appear in network settings post-uninstallation.
Step-by-Step Troubleshooting Approach
1. Verify Physical Connections
Ensure that your Ethernet cable is functioning correctly. Testing the cable on another computer can confirm its integrity. Confirm that the cable is securely plugged into both your PC and the router or switch.

Switch the Ethernet cable to a different port on your router. If possible, connect to a different router or network device to rule out port-specific issues.
