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

Updated Sources linked 4 min read October 3, 2026 · by Ryan Bennett

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:

Reseat the Ethernet cable at both ends — the router port and the PC port. Make sure it clicks in.
On a router/modem combo, plug into a regular LAN port, not the “Internet”/WAN port reserved for the modem feed.
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.

Stack/network resets can interrupt the current connection and alter custom networking. Record static IP/DNS, VPN and virtual-switch settings and keep a local recovery route before using them on a managed or remotely accessed PC.

Fix 2: Reset the network stack and renew the IP

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

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

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

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

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: Prepare and restore the network adapter driver

Before uninstalling or removing a driver package, download the correct Wi-Fi/Ethernet driver for your exact PC/adapter and Windows version from its manufacturer’s site. Save the installer locally or on a USB drive. If this PC cannot connect, download it on another device and transfer it by USB. Know how to run that installer offline.

In Device Manager → Network adapters, open the affected adapter’s Properties → Driver. If the issue began after a driver update and Roll Back Driver is available, try that first.
If reinstalling is necessary, choose Uninstall device. Initially leave Attempt to remove the driver for this device unticked unless a package replacement is specifically needed and the offline installer is ready.
Save work and restart. Windows may reinstall an available driver, but that is not guaranteed. If networking is still unavailable or the device has no driver, install the saved manufacturer package and restart as required.

Avoid removing your only working network driver’s package without a tested recovery route.

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.

Go to Settings > Network & internet > Ethernet.
Next to DNS server assignment, click Edit, choose Manual, and turn on IPv4.
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.
