How to fix Ethernet not working in Windows 11

Fix 1: Check cable and restart

Let’s first go with the basic and general fixes first. One of the most common causes for Ethernet network to disconnect or simply not working in Windows 11 is cable issue.

  • Check the LAN cable to see if there is any damaged part or excessively bent in any spot.
  • Check to see if the connector is loose. Unplug and plug in the cable connector again on both ends – your computer and the router.
  • If you have a spare LAN cable, try to replace the existing cable with the spare one and see if it works.
  • Restart both your computer and the router/modem. To reboot a router, you can simply turn off its power and then turn it back on.

Fix 2: Update Ethernet adapter driver

A driver tells the operating system (Windows 11) how to work with a piece of hardware. Corrupted or outdated Ethernet adapter driver can cause issue and failing to establish a successful network connection. The following steps show you how to update Ethernet driver in Windows 11.

1. Search for “Device Manager” via Start and open it.

Open Device Manager Windows 11

2. Expand the Network adapters category. Then, right-click your Ethernet adapter and select Update driver.

3. Next, select “Search automatically for drivers” to allow Windows to automatically search for the best available driver and install it for your computer.

If Device Manager shows “The best drivers for your device are already installed”, select “Search for updated drivers on Windows Update” and run Windows Update. This will allow Windows 11 to automatically search the Microsoft’s driver repository for the best available driver for your Ethernet adapter.

Ethernet adapter not listed in Device Manager in Windows 11

If the Ethernet adapter is not even listed in Device Manager, it might indicate hardware failure issue. You may need to replace your Ethernet adapter. If the broken Ethernet adapter is a built-in part, you can buy a PCIe Ethernet network card (if you have any empty PCIe slot left on your motherboard) or a USB Ethernet adapter instead.

Though extremely rare, it may also be due to that Windows 11 couldn’t detect and find the driver for your Ethernet adapter. In that case, you will have to manually find the driver from the Ethernet adapter manufacturer’s website or by using the driver CD that came with the Ethernet adapter (or your laptop or desktop computer if you bought your PC in full set).

Fix 3: Uninstall and reinstall Ethernet adapter driver

Uninstall a driver is one of the most common solution for many driver related issues in Windows. By uninstalling a driver, on next Windows startup, Windows will automatically attempt to detect, search for, and install the correct and up to date driver for your device.

Doing so will be as if you are freshly plugging in your Ethernet adapter and Windows will automatically detect it and install the right driver for it. Follow the steps below to do so.

1. Go to Start menu, search for and open “Device Manager“.

2. Next, expand the “Network adapters” category. Right-click your Ethernet adapter and select “Uninstall driver“.

Fix 5: Check if your Ethernet adapter is obtaining IP address automatically

If you have incorrect local IP address settings, it may cause IP conflicts within the network and ultimately fail to establish a successful network connection. Check the IPv4 settings of the Ethernet adapter to see if it has the correct IP obtaining settings.

1. Follow step 1 in Fix 4 above to open the Network Connections Control Panel window.

2. Right-click the Ethernet adapter and select Properties.

3. Next, in the “This connection uses the following items” section, select “Internet Protocol Version 4 (TCP/IPv4)” and then click Properties.

4. If the “Use the following IP address” option is selected, make sure the IP addresses are correct and intended. Before making any changes, jot down the current IP address settings in case you want to undo the changes later. If you have a specific network settings that require these IP settings, leave it as it is. Otherwise, try to select “Obtain an IP address automatically” and click OK.
