Windows updates are important for maintaining system security, improving stability, and adding new features. However, sometimes an update can unintentionally cause network-related issues. One common problem users encounter is the wired Ethernet connection not working after installing a Windows 11 update. When this happens, the system may fail to detect the Ethernet cable, show “No Internet access,” or stop connecting to the network entirely.
This issue can occur due to incompatible network drivers, changes in network configuration, disabled network adapters, or corrupted system files introduced during the update process. In some cases, the Ethernet connection may appear connected but still fail to access the internet.
Fortunately, there are several troubleshooting steps you can follow to restore your wired internet connection. In this guide, we will walk you through the most effective methods to fix wired internet not working after a Windows 11 update.
How to Fix Windows 11 Wired Internet Not Working After an Update
Follow the solutions below to restore your Ethernet connection.
1. Restart Your Computer and Router
Temporary glitches caused by system updates or network services may interrupt the internet connection.
- Save your work and close all running applications.
- Click the Start button.
- Select the Power icon.

- While your computer restarts, unplug the router or modem from the power source.
- Wait about 30 seconds, then reconnect the power cable.
- Allow the router to fully restart.
- After your computer boots up, check if the Ethernet connection works.
Restarting both devices refreshes the network connection and clears temporary issues.
2. Check the Ethernet Cable and Port
Before changing system settings, verify that the hardware connection is working properly.
