Computer Not Detecting Ethernet Cable? Here’s What To Do

The Ethernet cable is the standard for connecting your computer to the internet. This connection can be lost or interrupted due to a number of different reasons. When you are experiencing this issue, it’s important to know what the problem may be and how to fix it. Here are some tips on how to troubleshoot problems with your Ethernet cable.

Troubleshooting a broken Ethernet cable

Ethernet cables are usually not expensive, so it’s best to contact the manufacturer if it breaks. However, there is a chance that you can fix the problem on your own. Here are some troubleshooting tips.

If the Ethernet cable is broken or damaged, you’ll need to replace it with a new one. Once you’ve replaced the cable, run an internet connection speed test to see if the problem has been fixed.

If you’re experiencing problems with connectivity but your internet connection speed test doesn’t show any issues, then this may be due to incorrect settings on your router or modem. Make sure that everything is set up correctly and try running another internet connection test.

If you’re still experiencing issues with connectivity after trying these steps, contact your ISP provider for assistance.

Troubleshooting a loose Ethernet connection

A loose connection can be caused by a number of things, including a dirty cable connector on your computer or a defective connector on the router.

If you suspect that the issue may be a dirty cable connector on your computer, you can use a cloth to clean the area around the port. You also want to check for any loose items near this port and remove them.

To fix a defective Ethernet cable, you will need to get a new one from your network provider. A damaged wire inside the cable could be causing the problem.

Troubleshooting an intermittent connection

When you’re experiencing an intermittent connection, you may notice that it is only happening when you are transferring large files or that the connection will drop every five minutes. This may be due to your cable not being able to handle the data transfer and eventually breaking down.

You can troubleshoot this problem by moving your cable away from any other cables and devices like printers, monitors, and speakers. This will help reduce interference and help your cable get a better signal of the internet signal.

If the problem persists after removing these devices, it may be because of a faulty cable (cable length, condition) or a bad port on your computer’s Ethernet card. A faulty cable can be tested by using another one or by moving it away from any other cables or devices. The port on your computer’s Ethernet card may need to be replaced if the problem still exists after testing with another cable.

Troubleshooting a disabled or missing network adapter

The first thing to do if you are experiencing issues with your Ethernet cable is to verify that the network adapter is enabled.

To do this, open Control Panel and go to Network Connections. If there are any disabled connections, right-click on them and enable them.

If there are no disabled connections, you may need to manually enable your network adapter by going into Device Manager. Here it will be listed as something like Network Adapter X (where X is a number). Browse through until you find your adapter’s name under Network Adapters. Right-click on it and click Properties. Under the General tab, make sure it says Enabled or Turn On depending on whether or not Enable was already checked off when you looked in Control Panel earlier.

Once you have enabled your network adapter, try connecting again.


There are a number of reasons why your computer is not detecting your Ethernet cable. The key to solving these issues is to isolate the problem by trying each of the troubleshooting steps in order, starting with the easiest fixes. Troubleshooting network connectivity can be frustrating, but by following these steps, you should be able to get your connection back up and running in no time.
