When Ethernet is not working in Windows 11 while Wi-Fi functions, the cause is usually a driver, cable, or adapter setting rather than your internet service. A structured check restores the wired connection in most cases.
Network problems are among the most common frustrations in any operating system because so many components must work together: the adapter, its driver, Windows settings, your router, and your internet service. The key to efficient troubleshooting is isolating where the problem lies. Once you know whether the issue is with your PC Rajatoto88 or the wider network, the right fix becomes clear and you avoid wasting time on the wrong area.
Common Causes
Before applying a fix, it helps to understand why this happens. Identifying the likely cause lets you go straight to the most relevant solution instead of trying everything at random. The most frequent causes are:
- A faulty cable or port
- Outdated or corrupted network drivers
- A disabled network adapter
- Incorrect network configuration
How to Fix It: Step by Step
Work through these steps in order, starting with the simplest. In most cases one of the earlier steps resolves the problem, so there is no need to continue once it is fixed:
- Check the Ethernet cable and try a different cable or port to rule out hardware.
- Open Settings > Network & internet > Advanced network settings and ensure the Ethernet adapter is enabled.
- Update or reinstall the Ethernet driver in Device Manager.
- Run the Network and Internet troubleshooter.
- Reset the network stack if the connection still fails.
If the Problem Persists
Testing the cable and reinstalling the adapter driver resolve most wired connection problems. If Wi-Fi works but Ethernet does not, the adapter driver or physical connection is almost always the cause.
How to Prevent It in the Future
To keep your connection stable going forward, update your network adapter driver from the manufacturer when you notice problems rather than waiting, and disable power management for the adapter so Windows does not switch it off to save energy. Restarting your router every few weeks clears its own memory and prevents many recurring issues. If problems appear across several devices rather than just your PC, the router or your internet service is the more likely cause, which helps you direct troubleshooting effort where it belongs.
Final Thoughts
Issues like this are common in Windows 11 and rarely mean your PC is failing. Working methodically from the simplest fix to the more involved ones is the fastest way to resolve them while avoiding unnecessary changes to your system. If none of the steps above resolve the issue, it is worth checking Microsoft’s official support pages or community forums, since a recent update may have introduced a known problem that Microsoft is actively working to fix. In that case, waiting for the next patch, or temporarily rolling back the change that caused it, is often the most sensible course of action.
