Ethernet Says "Unidentified Network, No Internet" on Windows 11? Here's the Fix

You plug in the Ethernet cable and Windows 11 shows the network as “Unidentified network” with “No internet access,” even though the cable is connected.

Why: The cable link is up, but Windows could not get a valid IP address and gateway from your router. That usually means the network stack is corrupted, the adapter pulled a bad address, or the network driver is misbehaving.

Fix 1: Check the cable and restart the router

Before touching software, rule out the obvious:

1. Reseat the Ethernet cable at both ends — the router port and the PC port. Make sure it clicks in.
2. On a router/modem combo, plug into a regular LAN port, not the “Internet”/WAN port reserved for the modem feed.
3. Unplug the modem and router from power for a full 30 seconds, then plug the modem back first, let its lights settle, then the router.

Open Settings > Network & internet and check whether it now reads Connected under your Ethernet connection.

Fix 2: Reset the network stack and renew the IP

If the cable is fine but you’re still unidentified, rebuild Windows’ network components.

1. Click Start, type cmd, right-click Command Prompt, and choose Run as administrator.

2. Run these commands in this exact order, pressing Enter after each:

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

3. Restart the PC. Windows cannot finish rebuilding these layers while they are in use.

netsh winsock reset clears the Winsock catalog, netsh int ip reset restores the TCP/IP stack to defaults, and the ipconfig commands drop the bad address, pull a fresh one from the router, and clear the DNS cache.

Fix 3: Reinstall the Ethernet adapter driver

A faulty or stale driver keeps the adapter from ever getting a valid address.

1. Right-click Start and open Device Manager.
2. Expand Network adapters.
3. Right-click your Ethernet adapter and choose Uninstall device.
4. Tick Attempt to remove the driver for this device, then click Uninstall.
5. Restart the PC. Windows reinstalls a clean default driver for the adapter on boot.

Fix 4: Set a public DNS or do a full network reset

If the connection finally shows “Connected” but pages still won’t load, the DNS resolver may be the holdout.

1. Go to Settings > Network & internet > Ethernet.
2. Next to DNS server assignment, click Edit, choose Manual, and turn on IPv4.
3. Set Preferred DNS to 8.8.8.8 and Alternate DNS to 8.8.4.4 (Google), or 1.1.1.1 / 1.0.0.1 (Cloudflare). Click Save.

Still stuck? As a last resort, use Settings > Network & internet > Advanced network settings > Network reset, click Reset now, then Yes. This wipes every adapter and all network settings back to default and restarts the PC.

FAQ

It started right after a Windows update. Updates can replace or corrupt the network driver. Fix 2 (the reset commands) and Fix 3 (reinstall the driver) are the targeted repairs.

Another device on the same cable works fine. Then the router and cable are good and the problem is on this PC — focus on Fix 2 and Fix 3.

Network reset says I’ll need to reinstall networking software. Yes. After a network reset you may need to set up VPN client software or Hyper-V virtual switches again, and re-enter saved Wi-Fi passwords.
