If Wi-Fi works but Ethernet does not, the missing piece is usually one of these:

1. Cable or port issue
   • Make sure the Ethernet cable is firmly plugged into both the router and the PC.
   • On the router, confirm the cable is in a LAN/Ethernet port, not the Internet/WAN port.
   • If possible, try a different Ethernet cable. If the second cable works, the first cable is the problem.
2. Windows not getting a valid Ethernet connection
   • Open Settings > Network & internet.
   • Check the Ethernet status at the top.
   • In Windows 11, it should show Connected. In Windows 10, it should show You're connected to the Internet.
   • If it shows Action needed or another error, select Ethernet to review the connection settings.
3. Router-side connection problem
   • Restart the modem and router:
     1. Unplug the router power.
     2. Unplug the modem power.
     3. Wait at least 30 seconds.
     4. Plug the modem back in and wait for the lights to stop blinking.
     5. Plug the router back in and wait a few minutes.
     6. Try Ethernet again.
   • This temporarily disconnects everyone on the Wi-Fi network.
4. PC network stack issue
   • Open Command Prompt as administrator.
   • Run these commands in order:
     • netsh winsock reset
     • netsh int ip reset
     • ipconfig /release
     • ipconfig /renew
     • ipconfig /flushdns
5. Adapter or driver issue
   • If the problem started after an update, uninstall the Ethernet network adapter driver and restart the PC. Windows will automatically reinstall the latest driver.
6. Hardware isolation test
   • Try the same router and cable with another Windows PC, or use a USB-to-Ethernet adapter if available.
   • If another PC also cannot connect by Ethernet, the problem is likely the router, ISP, or adapter.
   • If another PC works, the issue is likely on the original PC.

If the PC has no built-in Ethernet port, a USB-to-Ethernet adapter may be required.
