You can connect your device, like a computer or smart TV, to the internet in two ways. You can connect your device via a cable or wirelessly. Both methods are effective and reliable.

But what if your wired connection (Ethernet) isn’t working yet your wireless connection (WiFi) is?

In this article, we’ll discuss how to troubleshoot your Ethernet connection. There can be many things that are interfering with your Ethernet connection.

We’ll discuss almost every single aspect of troubleshooting your ethernet connection. But first, let’s briefly discuss the most common issue that occurs in Ethernet connections:

Windows Troubleshooter

Now that I’ve come to the conclusion that the connection problems are only related to the PC and not the router or Internet service provider, you should try using the Windows troubleshooter to resolve the problem. Too frequently, the value of this diagnostic tool is disregarded.

The first thing it will do is anything you can perform manually (most things). Second, even if it’s unable to assist you, it will help you comprehend the root of the issue.

Therefore, feel free to use the Windows troubleshooter to resolve any network-related problems, including the one we’re dealing with right now. The procedures to execute it on Windows 10 are as follows:

  • To launch Settings, press and hold the Windows + I buttons at the same time.
  • Open the Update & Security section.
  • The Troubleshoot button can be chosen from the list on the left.
  • To run the troubleshooter, select Internet Connection Troubleshooter and highlight it.
  • Wait for the troubleshooting to be finished, then try to resolve the Wi-Fi connection problem.
  • The Incoming Connections troubleshooter can also be used.

Drivers are known as the software that makes hardware recognize and run in a proper way. Sometimes, drivers aren’t correctly installed, or driver files could be corrupted somehow.

It’s easy to reinstall or update your Ethernet drivers, though. Follow the given steps to do so:

  • Press the Windows key and type device manager, and press enter.
  • Now locate “Network adapters” and double-click on it to expand the list.

A damaged LAN wire could be causing the problem, it might be the LAN connector or a physically damaged wire.

You can physically inspect the wire that can be damaged by some kind of tearing or stretching by simply inspecting the connectors, known as RJ-45 connectors.

If any one of them looks damaged or not proper, then buy a new cable and repair the existing one.

Router’s Ethernet Port

It might be possible that your router‘s Ethernet port is faulty.

A typical router contains multiple Ethernet ports for multiple devices to communicate with, and there’s a simple fix that just switches the Ethernet port.

Try connecting the wire to another port on the back of the router.

If this doesn’t fix your problem, then your router’s port is not faulty, and you can now move on to the next troubleshooting step.

It’s also possible that your device (PC, smart TV, etc.) has a faulty Ethernet port. You can check the port by physically inspecting it with the naked eye.

If it looks normal, you can try different possibilities with which you can connect your device to the internet.

  • Try using wireless methods, every smart TV now has WiFi support.
  • If your PC doesn’t have Wi-Fi support, then try using a WiFi adapter. WiFi adapters are relatively cheaper and can be purchased from online stores or any computer hardware store.
  • There are also some USB-to-Ethernet adapters available in the market, but they are less powerful and would now give you the speed and consistency that your ISP (Internet Service Provider) offers.
  • There are some excellent quality USB-to-Ethernet adapters that provide comparatively better speed and consistency, but they are too expensive to afford.
