THE SHORT ANSWER

If Windows 11 says Ethernet is connected but has no internet, test another device on the same cable or router port, restart the PC, check the IP address, flush DNS, disable VPN or proxy, then update or reinstall the Ethernet adapter driver.

If Wi-Fi works on the same PC, the issue is probably the wired adapter, cable, driver or Ethernet profile. If Wi-Fi and Ethernet both fail, look at DNS, VPN, router or provider service.

Connected only means the cable link exists

Windows 11 can show Ethernet as connected when the physical link is fine but the internet path is broken. That means your computer can detect something at the other end of the cable, usually a router, switch or wall jack. It does not prove the PC has a valid IP address, working default gateway, usable DNS server or clean route to the internet. This is why the status feels misleading: the cable is alive, but websites still fail.

The best way to fix it is to separate the wired path into pieces. First prove whether the cable and router port work with another device. Then check whether Windows has a normal local IP address, whether DNS resolves names, and whether VPN or proxy settings are intercepting traffic. That order prevents unnecessary router resets.

Try these fixes in order

Keep the checks in order. Start physical, then local Windows settings, then router and provider clues.

  1. 01

    Test the cable and router port

    Plug another device into the same cable and router port. If that device gets internet, the cable path is probably fine and Windows needs attention.

  2. 02

    Restart the PC and disable Wi-Fi for one test

    Restart Windows fully, then turn Wi-Fi off so Ethernet is the only active path. This avoids confusing results from two networks at once.

  3. 03

    Check the IP address

    Open Command Prompt and run ipconfig. If the IPv4 address starts with 169.254, Windows did not get a usable address from the router.

  4. 04

    Renew IP and flush DNS

    Run ipconfig /release, ipconfig /renew and ipconfig /flushdns from an admin Command Prompt. Then test a normal website again.

  5. 05

    Turn off VPN, proxy and custom DNS

    VPN clients, proxy settings and custom DNS can break only one Windows device. Test automatic settings before changing router hardware.

  6. 06

    Update or reinstall the Ethernet driver

    Use Windows Update or the computer maker’s support page. If the issue began after an update, rolling back the driver may also help.

  7. 07

    Restart the router if more devices fail

    If another wired or wireless device also has no internet, restart the router and modem normally. Save factory reset for much later.

Detailed checks

CHECK 01

Understand 169.254 addresses

A 169.254 address is Windows giving itself a fallback address because it did not receive one from the router.

  • That fallback can make Ethernet look connected locally while internet access fails.
  • Fix DHCP, cable, router port or adapter driver before chasing browser settings.
CHECK 02

Separate DNS from the cable

If you can ping an IP address but websites fail by name, DNS is likely broken.

  • Set DNS back to automatic first, then test a trusted public DNS only if automatic fails.
  • Do not make permanent DNS changes until you know they helped.
CHECK 03

Check wall jacks and switches

If the PC is connected through a wall jack or small switch, test directly at the router.

  • A bad wall run can give a link light while failing reliable traffic.
  • If direct router Ethernet works, the room path is the next suspect.
CHECK 04

Use Windows Network Reset near the end

Windows Network Reset can help when the adapter stack is badly stuck, but it removes saved adapters and network settings.

  • Use it after cable, IP, DNS, VPN, proxy and driver checks.
  • After reset, restart the PC and test Ethernet before turning VPN or custom DNS back on.
CHECK 05

Check whether local network still works

If you can open your router page but websites fail, the Ethernet cable is carrying local traffic.

  • That points more toward DNS, gateway, VPN or the router’s internet connection than a dead cable.
  • If even the router page will not open, return to cable, port, adapter and IP address checks.

Mistakes to avoid

Do not assume connected means the internet path is working.

Do not ignore a 169.254 IP address.

Do not compare Ethernet on one PC with Wi-Fi on another and call it equal.

FAQ

Why does Windows 11 say Ethernet connected but no internet?

The physical cable link may be working while IP assignment, DNS, gateway settings, VPN, proxy or the router’s internet connection is failing.

Start by testing another device on the same cable and checking the Windows IP address. That tells you whether the problem is the cable path or Windows networking.

What does a 169.254 IP address mean?

It usually means Windows could not get a proper IP address from the router using DHCP.

Try another cable or port, then renew the IP address. If several devices get the same problem, restart the router.

Should I flush DNS?

Yes, but after basic cable and IP checks. DNS problems can stop websites from loading even while Ethernet is connected.

Flushing DNS is low risk. Permanent DNS changes should wait until you prove DNS is the cause.

Can VPN cause Ethernet no internet?

Yes. A VPN can break browsing or Windows network status on one computer while every other device works.

Turn it off briefly if allowed, then test again. If internet returns, adjust the VPN instead of changing the router.

This is especially common on work laptops where security tools control DNS, proxy and traffic routing.

When should I call the internet provider?

Call when multiple devices lose internet, the modem lights change, or direct Ethernet to the router fails on more than one computer.

If only one Windows 11 PC fails, keep working on adapter, driver, IP, DNS and software first.

Should I use Windows Network Reset?

Use it late, not first. It can clear corrupted adapter state, but it also removes saved network settings.

Before using it, record any special VPN, proxy, static IP or DNS settings you may need again.
