How to Fix “Network Cable Unplugged” on Windows 11

Seeing the “Network cable unplugged” message on Windows 11 can be frustrating, especially when your Ethernet cable is connected and your internet was working normally a few minutes ago.

This message usually means Windows cannot detect an active wired network connection. The problem might be as simple as a loose cable, a faulty router port, or a disabled Ethernet adapter. In other cases, an outdated driver, a docking station, or a failing network card may be responsible.

The important thing is to identify where the connection is breaking instead of changing random network settings.

In this guide, you will learn how to fix the “Network cable unplugged” error on Windows 11, how to check whether the problem comes from your cable or computer, and what to do if the message keeps returning.

What Does “Network Cable Unplugged” Mean?

Windows displays this message when it cannot detect a physical Ethernet connection between your computer and the network equipment.

It does not necessarily mean that someone has physically removed the cable. Windows may report the same error when:

• The Ethernet cable is loose or damaged.
• The router or switch port is faulty.
• The router, switch, or computer’s network adapter is turned off or malfunctioning.
• The Ethernet adapter has a driver problem.
• A USB Ethernet adapter or docking station is not working correctly.
• The network adapter fails to establish a connection after the computer wakes from sleep.

There is an important distinction here: a disconnected Ethernet link is different from an Ethernet connection that has no internet access.

If Windows detects the cable but cannot reach the internet, you may see messages such as “No Internet,” “Unidentified Network,” or “Default Gateway Is Not Available.” If Windows reports that the network cable is unplugged, start by checking the physical connection and the adapter itself.

1. Check Both Ends of the Ethernet Cable

Start with the simplest possible fix. A cable can look connected while its plug is not fully seated in the port.

Follow these steps:

1. Locate the Ethernet cable connected to your computer.
2. Unplug it carefully from the computer’s Ethernet port.
3. Reconnect it until the connector clicks into place.
4. Follow the cable to the router, modem, or network switch.
5. Disconnect and reconnect the other end.
6. Wait around 10–15 seconds to see whether Windows detects the connection.

Check the plastic locking tab on the connector, too. If the tab is broken, the plug may slip out of the port or fail to maintain a reliable connection.

If your computer is under a desk or connected to equipment in another room, inspect the entire cable for sharp bends, crushed sections, damaged connectors, or places where furniture may have pinched it.

Why this works: Ethernet ports rely on a physical connection between devices. A loose connector can prevent the network adapters from establishing a link, even when the cable appears to be in place.

If the error remains, continue to the next step rather than repeatedly reconnecting the same cable.

2. Try a Different Ethernet Cable

A damaged cable is one of the most common things worth ruling out.

An Ethernet cable can develop internal wire damage from being bent too tightly, pulled, stepped on, or trapped under furniture. Sometimes the outside insulation looks perfectly normal even though the cable no longer works reliably.

To test it:

1. Disconnect your current Ethernet cable.
2. Find another Ethernet cable that you know works.
3. Connect the replacement cable to your computer and router.
4. Wait a few seconds for Windows to detect the connection.
5. Check whether the “Network cable unplugged” message disappears.

If the replacement cable works, the original cable is probably damaged or defective.

You do not need an expensive cable for this test. A suitable, working Ethernet cable that supports your network speed is enough.

If the new cable produces the same error, do not immediately assume that your computer’s network card is broken. The router port, adapter settings, or driver could still be responsible.

3. Switch to Another Router or Switch Port

Your cable may be fine while the port at the other end is not.

Routers and network switches usually have several Ethernet ports. If one port is damaged or malfunctioning, another port may establish a connection normally.

Try this:

1. Leave the Ethernet cable connected to your computer.
2. Disconnect the other end from its current router or switch port.
3. Connect it to another available LAN port.
4. Wait several seconds.
5. Check whether the Ethernet status changes in Windows.

Make sure you understand which port you are using. On many home routers, the WAN or Internet port is intended for the incoming internet connection, while LAN ports connect computers and other local devices. Connecting your computer to the wrong port may prevent it from joining the network.

Also check whether the router or switch is powered on and functioning normally.

Some Ethernet ports have indicator lights that help show link activity. If your equipment has these lights, check whether they illuminate after connecting the cable. However, not every device uses the same light behavior, and some devices have no visible indicators at all.

If one port works and another does not, the problem may be limited to the original port.

4. Restart Your Computer and Network Equipment

Sometimes a network adapter or router gets stuck in a state where it fails to establish a connection correctly.

Restarting the devices can clear a temporary problem.

Restart Windows 11

1. Save your work and close open applications.
2. Open the Start menu.
3. Select Power.
4. Choose Restart.
5. After Windows loads, check the Ethernet connection.

Restart your router or switch

If restarting the computer does not help, restart your network equipment if you have permission to do so.

1. Disconnect the router or switch from its power source, following the manufacturer’s instructions.
2. Wait approximately 30 seconds.
3. Restore power.
4. Allow the equipment to finish starting up.
5. Check the Ethernet connection again.

If your internet service uses a separate modem and router, follow the equipment manufacturer’s recommended restart procedure. When restarting both, the modem generally needs to establish its connection before the router can provide internet access.

Keep in mind that restarting your router may temporarily disconnect other people and devices in your home. Avoid restarting shared workplace equipment without authorization.

If Windows still reports that the cable is unplugged, move on to the network adapter checks.

5. Check Whether the Ethernet Adapter Is Enabled

Windows can show an Ethernet adapter as disconnected if the adapter has been disabled.

This can happen after changing network settings, installing software, or troubleshooting another connection problem.

To check its status:

1. Press Windows + R.
2. Type ncpa.cpl.
3. Press Enter.
4. Find the connection named Ethernet.

Look at the connection status.

• If the adapter is labeled Disabled, right-click it and select Enable.
• If it is enabled but reports that the network cable is unplugged, continue troubleshooting the cable, port, and adapter.
• If no Ethernet connection appears, Windows may not be detecting the adapter correctly.

You can also open Settings and navigate to Network & internet to review the available network connections.

If Ethernet does not appear in either location, open Device Manager and check whether the network adapter is listed there.

6. Disable and Re-enable the Ethernet Adapter

Even when the Ethernet adapter is enabled, temporarily turning it off and back on can help resolve a temporary driver or device-state problem.

Here is how to do it:

1. Press Windows + R.
2. Enter ncpa.cpl.
3. Press Enter.
4. Right-click Ethernet.
5. Select Disable.
6. Wait about 10 seconds.
7. Right-click the adapter again.
8. Select Enable.

Wait a few seconds for Windows to detect the network link.

If your computer has both Wi-Fi and Ethernet, you can leave Wi-Fi connected while performing this test. Just remember that working Wi-Fi does not prove the Ethernet adapter is functioning properly.

If the Ethernet connection returns, test it for a few minutes. If the error comes back whenever you restart or wake the computer, the driver or power-management settings deserve closer attention.

7. Troubleshoot the Ethernet Driver

The Ethernet driver allows Windows to communicate with the physical network adapter. A corrupted, incompatible, or problematic driver can interfere with the connection.

This is particularly worth checking if the problem began after a Windows update, a driver update, or installing new hardware.

Open Device Manager

1. Right-click the Start button.
2. Select Device Manager.
3. Expand Network adapters.
4. Look for an Ethernet adapter. Its name might include Intel, Realtek, Broadcom, or another hardware manufacturer.

Check whether the device has a warning symbol or appears to be disabled.

Update the driver

1. Right-click the Ethernet adapter.
2. Select Update driver.
3. Choose Search automatically for drivers.
4. Follow any instructions Windows provides.

Windows may report that the best available driver is already installed. This does not always mean that the manufacturer’s latest compatible driver is installed.

If updating through Windows does not help, visit your computer manufacturer’s official support website. Search for your exact computer model and download the appropriate Ethernet or LAN driver for Windows 11.

For a desktop computer with a separate network card, use the motherboard or network card manufacturer’s official support page.

Avoid downloading drivers from unfamiliar websites or third-party driver-updater applications.

Roll back a recent driver update

If Ethernet stopped working immediately after a driver update, rolling back the driver may be more useful than installing another one.

1. Open Device Manager.
2. Right-click the Ethernet adapter.
3. Select Properties.
4. Open the Driver tab.
5. If Roll Back Driver is available, select it.
6. Follow the prompts and restart the computer if requested.

The rollback option may be unavailable if Windows has no previous driver version stored.

Reinstall the driver if necessary

If the driver appears corrupted, reinstalling it may help.

Before uninstalling the existing driver, download the correct replacement from the manufacturer’s official website if possible. This is especially important if Ethernet is your only way to access the internet.

Then, in Device Manager, right-click the Ethernet adapter and select Uninstall device. Follow the available prompts, then restart Windows or reinstall the downloaded driver according to the manufacturer’s instructions.

Be careful with any option that removes the driver package entirely. You should have a compatible replacement available before removing it.

8. Check Ethernet Power Management Settings

Does the error appear after your laptop wakes from sleep, resumes from hibernation, or remains idle for a long time?

If so, check whether Windows is allowing the network adapter to be turned off to save power.

1. Right-click Start.
2. Open Device Manager.
3. Expand Network adapters.
4. Right-click your Ethernet adapter and select Properties.
5. Look for the Power Management tab.
6. If the option is available, review the setting that allows the computer to turn off the device to save power.

As a test, you can clear that checkbox and click OK.

The exact options depend on the adapter and its driver. Some devices do not show a Power Management tab.

Restart the computer or put it to sleep and wake it again to test the result.

Changing this setting may increase power consumption slightly, so there is no need to disable power-saving features on every network adapter. Focus on this test when the problem appears related to sleep or power transitions.

9. Check Speed and Duplex Settings

Ethernet adapters sometimes have configurable link-speed and duplex settings. An incompatible setting can prevent certain devices from establishing a link.

However, these settings should not be your first troubleshooting step. A damaged cable or defective port is usually more important to rule out.

If you have already tested another cable and another port, inspect the adapter settings.

1. Open Device Manager.
2. Expand Network adapters.
3. Right-click your Ethernet adapter and select Properties.
4. Open the Advanced tab.
5. Look for a setting named Speed & Duplex or something similar.

If the current setting has been manually changed, try restoring it to Auto Negotiation or the equivalent automatic option.

Click OK and check whether the connection returns.

The available values vary by adapter, and forcing a speed such as 100 Mbps or 1.0 Gbps may cause a connection mismatch if the other device does not support the same setting.

If you are using a managed office network, follow your IT team’s instructions instead of changing advanced adapter properties without authorization.

10. Troubleshoot a USB Ethernet Adapter or Docking Station

Not every computer has a built-in Ethernet port. Some laptops connect through a USB-to-Ethernet adapter, USB-C hub, or docking station.

If you use one of these devices, the connection problem may not be related to the Ethernet cable alone.

Try the following checks:

1. Disconnect the USB Ethernet adapter or docking station.
2. Reconnect it securely.
3. If possible, try another compatible USB port.
4. Connect the Ethernet cable directly to the adapter, bypassing any unnecessary hubs.
5. Test a different Ethernet cable.
6. Check Device Manager to see whether Windows recognizes the adapter.
7. Install the manufacturer’s compatible driver or firmware updates if required.

If the adapter has a USB-C connector, make sure the port and adapter support the functionality you need. A charging-only cable or incompatible accessory will not necessarily provide Ethernet connectivity.

For a docking station, check whether other devices connected through the dock are working. If several dock functions fail at once, the dock’s power supply, USB connection, firmware, or host connection may be responsible.

If possible, test the same Ethernet adapter on another compatible computer. This helps determine whether the fault follows the adapter or remains with your Windows installation.

11. Reset Windows Network Settings

Windows 11 includes a Network reset feature that reinstalls network adapters and restores certain network settings to their defaults.

However, there is an important limitation: a network reset cannot repair a physically disconnected Ethernet link.

If Windows continues to report “Network cable unplugged” because the cable, port, or network card cannot establish a connection, reset settings only after you have checked those components.

To perform a network reset:

1. Open Settings.
2. Select Network & internet.
3. Choose Advanced network settings.
4. Select Network reset.
5. Click Reset now.
6. Confirm the action and allow Windows to restart if prompted.

Before doing this, be aware that Windows may remove and reinstall network adapters and reset network configuration. You may need to reinstall VPN software, configure virtual network adapters again, or adjust other networking software afterward.

After restarting, reconnect the Ethernet cable and check the connection status.

What about Command Prompt network commands?

Commands such as ipconfig /release, ipconfig /renew, and ipconfig /flushdns can help with certain IP-address or DNS problems.

They are not the right first fix when Windows reports that the Ethernet cable is unplugged. If the network adapter cannot detect a physical link, releasing or renewing an IP address will not repair the cable or establish the missing connection.

Use IP configuration commands only after the Ethernet link is detected and you are troubleshooting a separate network-configuration problem.

12. Test the Cable and Adapter on Another Device

If you have tried the previous methods without success, perform a simple isolation test.

The purpose is to find out whether the problem follows the cable, the computer, or the network equipment.

Try these combinations:

• Test A: Connect your current computer to the router using a known-working Ethernet cable.
• Test B: Connect another computer to the same router port using that cable.
• Test C: Connect your current computer to a different known-working Ethernet network, if available.
• Test D: If you use a USB Ethernet adapter, test it on another compatible computer.

Interpret the results carefully.

If another computer works with the same cable and port: Your computer’s Ethernet adapter, driver, or configuration becomes a stronger suspect.

If neither computer works with the original cable but both work with another cable: The original cable is likely defective.

If one router port fails but another works: The original port or its configuration may be the problem.

If your computer fails on multiple known-working cables and networks: The Ethernet adapter, its driver, or the computer’s hardware deserves closer inspection.

These tests are more useful than changing several Windows settings at once because each one helps narrow down the cause.

13. When to Contact Your Internet Provider or IT Team

If you have checked the cable, tried another port, and tested the Ethernet adapter without success, you may need help with the network equipment or computer hardware.

Contact your internet provider if the incoming connection or provider-supplied equipment appears to be malfunctioning. However, remember that a “Network cable unplugged” message on your computer does not automatically mean your internet provider has an outage. It can indicate a problem with the local connection between your computer and router.

If you are using a workplace network, contact your IT team before changing managed network settings. They may need to check switch ports, VLAN assignments, access controls, docking stations, or other equipment.

If the computer cannot establish an Ethernet link using multiple known-working cables and ports, a technician can test the physical Ethernet interface. A faulty built-in network port may require repair or replacement, although a compatible USB Ethernet adapter can sometimes serve as an alternative.

Frequently Asked Questions

Why does Windows 11 say my network cable is unplugged when it is connected?

Windows displays this message when it cannot detect an active Ethernet link. A loose connector, damaged cable, faulty router port, disabled adapter, driver issue, or defective network interface can cause the problem even when the cable is physically connected.

Start by reseating both ends of the cable and testing a different cable and router port.

Can a faulty Ethernet cable cause this error?

Yes. An Ethernet cable with damaged internal wires or defective connectors may prevent the devices from establishing a link. Replacing it temporarily with a known-working cable is one of the quickest ways to test this possibility.

Will restarting my router fix the problem?

It may help if the router or switch is temporarily malfunctioning. However, restarting will not repair a damaged cable, broken connector, or faulty network card. Test the physical connection first.

Should I reset TCP/IP to fix “Network Cable Unplugged”?

Not as your first step. TCP/IP resets and IP configuration commands address network configuration problems, but they cannot repair a missing physical Ethernet link. Confirm that Windows detects the cable before troubleshooting IP settings.

Why does Ethernet work after restarting but disconnect again later?

A recurring problem may involve a faulty cable or port, an unstable adapter driver, power-management settings, a docking station, or failing hardware. If it happens after sleep, check the adapter’s power-management options. If it happens during normal use, test a different cable and port first.

Why is Ethernet missing from Device Manager?

The adapter may be disabled, not detected by Windows, affected by a driver problem, or experiencing a hardware issue. Check Device Manager for disabled devices and unknown devices, then inspect the manufacturer’s recommended drivers. If the adapter is still missing, consult the computer manufacturer’s support guidance.

Does “Network Cable Unplugged” mean my internet is down?

Not necessarily. The message usually indicates that Windows cannot detect the wired connection between your computer and the next network device. Your internet service may be working normally for other devices connected through Wi-Fi or other Ethernet ports.

Conclusion

The “Network cable unplugged” error on Windows 11 does not always mean that your Ethernet cable has been physically removed. Windows can show the same message when a cable is damaged, a router port fails, a network adapter is disabled, or a driver cannot establish the connection correctly.

Start with the physical checks: reconnect both ends, test another cable, and switch to another router or switch port. If those steps do not help, inspect the Ethernet adapter in Windows, troubleshoot its driver, and check power-management settings if the issue occurs after sleep.

Save network resets and advanced configuration changes for later. If Windows still cannot detect a connection after testing known-working cables and ports, investigate the network adapter or seek hardware support.

Working through these checks in order will help you identify the likely cause without making unnecessary changes to your Windows network settings.
