If an Ethernet connection is not working in Windows 11, the PC may show no internet, an unidentified network, or no wired connection at all. Work through these checks before replacing your network hardware.

1. Check the Ethernet cable

Make sure the cable is firmly connected to the PC and router. Try another Ethernet cable or another router port if available.

2. Restart the router and PC

Restart the router, wait for it to reconnect, then restart Windows. Test the wired connection again.

3. Check the Ethernet adapter

1. Open Settings → Network & internet → Advanced network settings.
2. Look for the Ethernet adapter.
3. Make sure it is enabled.

4. Update the network driver

Open Device Manager, expand Network adapters, and update the Ethernet adapter driver. If necessary, download the correct driver from your PC or motherboard manufacturer’s official support page.

5. Run the network troubleshooter

Open Windows Settings and use the available network troubleshooting options. Follow the recommended steps and test the connection afterward.

6. Reset network settings

If the adapter appears normal but Windows still cannot connect, use Settings → Network & internet → Advanced network settings → Network reset. Note that this removes saved network information and may require you to reconnect afterward.

Final thoughts

Check the cable and router first, then investigate the Ethernet adapter and driver. A network reset is best saved for later because it changes saved network configuration.

If an app will not open in Windows 11, it may close immediately, do nothing when clicked, or display an error. These fixes can help with damaged app files, updates, permissions, and Windows components.

1. Restart Windows
