Fortunately, the issue can be resolved with proper diligence. In this post, let us look at some ways you can resolve the error and make the most out of your Realtek Ethernet Controller Driver.
Without further ado, let’s get started!
How to Fix Realtek Ethernet Controller Driver Not Working
To fix the issue, you must first identify the cause of it. For most users experiencing it, the issue has appeared after upgrading to Windows 10, which boils down to compatibility errors.
Since the Windows environment in which the ethernet controller is being used has changed, a few settings must be changed, too. Check out the following fixes to help you regain compatibility and fix the Realtek Ethernet issue.
Fix 1 – Reset the TCP/IP User Log
When you have older logs combined with newer ones, the issue is bound to appear. Hence, the best way to handle things is by resetting the data your current TCP/IP log holds. Follow the steps to do the same –
Step 1 – Go to the Start menu and search for the Command Prompt.
Step 2 – Launch the Command Prompt as administrator for all the permissions.
Step 3 – In the Command Prompt window, use the following command and hit enter –
netsh int ip reset c:\resetlog.txt
Step 4 – After using the command, restart your computer and check if you still have the ethernet issue.
This way, you will reset the log, creating room for newer entries compatible with Windows 10.
Fix 2 – Update Realtek Ethernet Controller Driver
Sometimes, when you have upgraded your OS, the required drivers are not updated. You have to do the same to ensure complete compatibility manually. The same can be the case with your current Realtek Ethernet Controller Driver. Hence, using the latest driver is the best way to make it work smoothly.

Fix 3 – Check Your Realtek Ethernet Controller Power Settings
When you upgrade, the power consumption often changes for connected devices. However, since the settings are only updated with your permission, it results in controller power management issues. Here are the settings that you should be concerned about –
Step 1 – Use the Start menu and navigate to Device Manager.
Step 2 – Spot your ethernet driver under the Network Adapter in the Device Manager.
Step 3 – Double-click on the device to open its properties.
Step 4 – In properties, navigate to the power management tab and disable the power management setting.
Step 5 – Later, move to the Advanced tab and scroll down to the Energy Efficient Ethernet setting. Check its value and disable it if it is enabled.
After making these changes, you can save them and exit. Restart the PC for changes to take complete effect. After the process is finished, you may find out that the issue is no longer bothering your PC.
Other than these fixes, you always have the option to uninstall the driver completely and reinstall it using the Device Manager. However, that is the last resort, as the above fixes will do the job for you. If you are unclear about any of the steps, feel free to contact us on our social media or via the comments section.
