The Ethernet is not working, but WiFi has an error is quite common and could be because of hardware flaws, incorrect settings, or missing drivers. Whatever the reason may be, we can fix it in no time.

Here in this guide, we will discuss the methods to fix Ethernet no internet, but WiFi works right after talking about the causes of the same.

Why does my WiFi work but not Ethernet?

There could be various reasons for the ethernet cable not working, but WiFi is; some of the most popular ones are mentioned below: 

  • Network cables – If your network cables are loosely attached or have suffered physical damage, you might not get internet via Ethernet. So check both ends of the cable to inspect the connection and damage.
  • Problem with your router or modem – The issue might occur if your router is not configured correctly. You need to restart your modem and router to see if it fixes the problem.
  • DHCP server – If your device is not getting an IP address from the router, there could be an issue with the DHCP server, which is why you can’t connect via Ethernet.
  • Third-party software interference – Security software can create conflict and block the connection. Check the software settings to ensure the Ethernet connection is not blocked.
  • Incorrect network configuration – If your device is not set up to use the correct subnet mask, IP address, and gateway, you might face the issue.
  • Issue with Network Adapter – If the network adapter on your computer is not enabled or working correctly, then the drivers on the computer might be outdated. You need to update drivers.
  • Too many devices connected to the same network – If you have exceeded your router’s device limit, it may cause congestion and hence the error.

What can I do if the WiFi works but the Ethernet doesn’t?

Before engaging in advanced troubleshooting steps, you should consider performing the following checks:

  • Check the ethernet cable for physical damage and loose connection. Unplug and replug it a couple of times to be sure.
  • Ensure the ethernet port is working. Try the cable on another device to check.
  • Restart your router and modem.
  • Turn off the WiFi feature.
  • Drain the residual power.
