Ethernet Connected but No Internet While Wi‑Fi Works
Asked by

My PC can access the internet over Wi‑Fi, but the connection does not work when I plug in an Ethernet cable. I've tried replacing the cable and checking various network and device settings, but nothing has helped so far. I'm looking for troubleshooting steps I may have missed.

Check the Ethernet driver directly on your motherboard or PC manufacturer’s support page. Download and install the latest wired-network driver rather than relying only on Windows Update.

Open Command Prompt as administrator and run these commands in order to reset Windows networking, renew your IP address, and clear the DNS cache: `netsh winsock reset`, `netsh int ip reset`, `ipconfig /release`, `ipconfig /renew`, and `ipconfig /flushdns`. Restart the PC afterward and test the connection again.
MellowOrbit42: I tried those commands, but unfortunately they didn’t fix it. Thanks for the suggestion, though.

Look at the Ethernet port and the router port when the cable is connected. Do you see link or activity lights? If there are no lights, try another router port and check whether the PC’s Ethernet adapter is enabled.

A few details can help narrow this down: did Ethernet work previously, does the router assign the PC an IP address through DHCP, can you ping the router, and do other wired devices work from the same router? These tests can show whether the problem is the cable or router, the PC’s network adapter, or the internet configuration.
