Most Windows 10 PCs connect to Ethernet automatically when you plug a working network cable into an enabled Ethernet adapter. Home routers normally provide the IP address and DNS configuration through DHCP, so manual network values are usually unnecessary.
Connect Windows 10 to Ethernet
- Connect one end of a compatible Ethernet cable to the PC or its USB/docking Ethernet adapter.
- Connect the other end to the correct router, switch, or approved network jack.
- Wait a few seconds for Windows to detect the connection.
- Open Settings > Network & Internet and check the Ethernet status.
- Open a website or approved network resource to test connectivity.
If Ethernet does not connect
Check the cable and link indicators, try a known-working router/switch port when appropriate, and inspect the Ethernet adapter in Device Manager. Obtain drivers from Windows Update or the PC/adapter manufacturer rather than a third-party driver site.
Do not enter a static IP unless the network requires one
Random IP addresses, gateways, and DNS servers can prevent connectivity or conflict with another device. In a workplace, school, lab, or server environment, use the values supplied by the network administrator.
Ethernet and Wi-Fi can both be enabled
Windows chooses routes based on its network configuration. You generally do not need to disable Wi-Fi just to use Ethernet, although doing so can simplify troubleshooting when you want to test only the wired connection.
Windows 10 is past standard support. Existing Ethernet configuration still works, but eligible connected PCs should migrate to a supported Windows release.
If you are using a USB Ethernet adapter or dock, test a direct built-in Ethernet port when available. Dock firmware, USB bandwidth, or adapter drivers can introduce a separate failure point.
If Ethernet shows a connection but Internet access still fails, compare another device on the same router and check the assigned IP address before changing DNS or firewall settings. A bad cable, switch port, router, or ISP connection can produce similar symptoms.
