Windows 11 Ethernet No Internet: Step-by-Step Cable Fixes

A wired connection is supposed to be the reliable one, which makes it all the more annoying when the Ethernet icon shows a globe or “No internet”. A Windows 11 Ethernet no internet problem can sit in four places: the cable and router port, the router or provider, Windows’ network settings, or the adapter driver. This guide follows Microsoft’s own order of fixes, from the quickest checks to a full network reset, and explains what each message means along the way.

The steps apply to Windows 11 version 24H2, 25H2 and 26H2, with built-in or USB Ethernet adapters.

Step 0: Is it just this PC?

Check another device on the same router, wired or on Wi-Fi. If nothing has internet, the problem is the router, the modem or the provider: restart them (Step 3) and check your provider’s status page. If only this PC is affected, carry on.

Step 1: Run the troubleshooter

Microsoft’s Ethernet page starts with the automated Network and Internet troubleshooter in the Get Help app. Search for Get Help in Start and type “network troubleshooter”, or open it from Settings > System > Troubleshoot > Other troubleshooters. It resets common settings and reports what it found.

Step 2: Check the cable and port

Microsoft’s checklist:

• Make sure the Ethernet cable is firmly plugged in at both the PC and the router.
• On the router, use a LAN port, not the internet or WAN port that connects to the modem.
• Try a spare cable if you have one.

Look for the small lights next to the Ethernet port on the PC and router: no light usually means no physical link, which points to the cable, port or adapter. If you use a USB Ethernet adapter or a dock, plug it directly into the PC and try a different USB port.

Step 3: Restart the modem and router

1. Unplug the router, then the modem. If the modem has a backup battery and its lights stay on, Microsoft suggests removing the battery.
2. Wait about 30 seconds.
3. Plug in the modem and wait until its lights settle.
4. Plug in the router and wait a few minutes before testing.

Step 4: Check the connection status

Open Settings > Network & internet. Under Ethernet, Microsoft says it should show Connected below the connection name. If it shows Action needed, select Ethernet to see the details.

What the common messages mean:

Message	Meaning	First fix
Network cable unplugged	No physical link	Cable, port, adapter (Step 2)
Unidentified network / no valid IP configuration	No valid address from the router	Restart router, run the commands below
Connected, no internet	Link and address fine, internet unreachable	DNS, proxy, VPN, provider

Also check the IP settings: select Ethernet, then next to IP assignment select Edit. For most home networks it should be Automatic (DHCP). Manual settings left over from another network are a common cause. The same applies to DNS server assignment.

Step 5: Try Wi-Fi as a comparison

If the router has Wi-Fi, connect the PC wirelessly for a moment. Internet over Wi-Fi but not Ethernet narrows the problem to the cable, port or Ethernet adapter.

Step 6: Run the network commands

Microsoft lists these commands, run in order in an administrator Command Prompt or Terminal (right-click Start > Terminal (Admin)):

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

Restart the PC afterwards. Together they reset the network stack, request a fresh IP address from the router and clear cached DNS entries. Our reset network settings in Windows 11 guide explains each one.

Step 7: VPN, proxy and security software

VPN clients and some security suites install network filter drivers that can block traffic when they misbehave.

• Disconnect or quit the VPN and test; see Windows 11 VPN not connecting.
• Check Settings > Network & internet > Proxy: Automatically detect settings is normally on, with no manual proxy unless you need one; see proxy settings.
• Temporarily turn off third-party firewall software to test.

Step 8: Reinstall the Ethernet driver

Before you start, Microsoft recommends downloading the latest network driver from the PC or adapter maker as a backup, because you may lose internet.

1. Right-click Start and select Device Manager.
2. Expand Network adapters and right-click your Ethernet adapter.
3. Select Uninstall device, tick Attempt to remove the driver for this device, and select Uninstall.
4. Restart. Windows reinstalls the adapter; if not, install the driver you downloaded.

If the adapter is missing from Device Manager entirely, check that onboard LAN is enabled in the BIOS/UEFI settings, or the adapter may be faulty.

Step 9: Network reset (last resort)

Microsoft lists Network reset as the final step: Settings > Network & internet > Advanced network settings > Network reset > Reset now > Yes. It removes and reinstalls all network adapters and resets their settings, so VPN software may need reinstalling and networks may come back as Public. See reset network settings for what to set up again.

Still stuck?

If Wi-Fi is also affected, see Windows 11 no internet. If Ethernet works but is slow or drops, check Ethernet settings and try another cable; damaged or very old cables can limit speed. For sharing and network drives once you are back online, see map a network drive.
