How to Fix: Ethernet Cable Not Working on Your PC?



Getting Started Troubleshooting (Ethernet Cable Not Working)

The first thing we want to point out is the many options because of which your ethernet cable is not working. For the structure of this article, we will try to focus on some of the more common and common causes but in reality, there can be many different variables. 


Some of the things you want to understand first are what type of products do you use? Here is a quick list of two things you want to know when trying to solve problems.


What type of cable do I use?

What is the main issue?

What devices do I use for the cable?


Knowing these will give you a good start in trying to understand the topic at hand. Familiarity with the cable you have will help you determine if it is compatible with the products you use. Boiling the subject gives you a good starting point in your research on how to fix it. 


Then knowing the third what type of devices you are using will filter out troubleshooting tips even further. 

Now hoping you have a summary of the problem and the products in your network let’s jump to some of the reasons why an Ethernet lan cable is not working.


1. Wrong Terminations on Your Wires

This is actually a fairly common phenomenon. If you have recently purchased an ethernet lan cable in bulk and are working on ending the cables this is something you can get into. Connecting Ethernet Cables in the Proper Wiring Program It is important for the success of your cable connection. 


Not only do you want the wires to be in the right order but you want both ends of an ethernet lan cable to be connected in the same plan for the fast internet. There are several ways you can disconnect your copper cables. 


You can make t568a or t568b. In North America, the more common wiring program is the t568b. We therefore recommend sticking to this order for easier troubleshooting. T568A is often used in Canada. You can technically escape using both programs but since b is used more stay with it.


2. Wires Are Not Inserted All the Way

The second issue regarding cable wiring may be that the wires are not inserted up to the plug. You want to make sure the copper wires are pushed to the ends of the RJ45 connectors. 

By doing so you ensure that the golden contacts on the wires can be contacted. It gives you a solid power connection.


3. Cable Not Plugged in All the Way

It seems like a pretty simple thing to do but you will be surprised at how often this is the reason for a bad connection. Make sure the Ethernet cables are securely connected to both ends of the lan cable for the fast internet. 

Whether you connect your cable to an Xbox PlayStation or PC with a cable plugged in all the way will ensure a connection can be made.


4. Turn off Wifi

If you are hardwiring an Ethernet cable to your devices and at the same time a WiFi operator can have a problem with the settings. If you use Windows your computer will likely access your Ethernet cable via WiFi but this is not always the case. 


If your cable does not work when you use both go to the network setup on your computer. Go to Open Network and Internet Settings. Look for the WiFi button and turn it off. 

At the same time, you want to find the connection setting to a local area and make sure it is turned on. Wait until you see the beginning of a connection and you should be good to go.


5. Try Another Ethernet Port

This can be a problem where your Ethernet port does not work. To determine if you have a faulty router or modem try connecting the Ethernet cable to another port on the device. A router usually comes with several Ethernet ports. These ports are called LAN ports and should be labeled as such. 


If you are unable to make a connection on the first port then let the second go. If that still does not work try the remaining ports. If there is still no success it may be because of a problem with your router. 

To confirm this you want to make sure you double-checked the direction with the router to confirm that the setting is done correctly. You can also try calling the device manufacturer for more information.


6. Try Another Ethernet Cable

Another step you can take is to try another Ethernet cable. If you happen to have another cable running check that this lan cable is working with the same Ethernet port. If there is still no connection after using another cable it may be a problem with the device settings. 


What you can also do with your cable is trying to connect it to another device. Not that you’re having a problem with him. 

Check if your cable works with this wifi device and it will add some insight into whether the ethernet cable is bad or not.


7. Update Computers Drivers

It is a good habit to create your own electronic device. Not only will updating your devices provide you with the latest technological changes in the software but it can also help with security patches and other bug fixes. 


The main reason why you want to update the drivers of your computers is to keep your CPU running smoothly. Drivers are on your computer to let your computer know how to work with other applications such as hardware devices.


8. Disconnect and Reinstall Devices

We have all experienced the issues with turning off WiFi signals. Our first thought is usually to disconnect the router and reconnect it. Surprisingly the problem is usually resolved after performing this action. 


The same idea can be applied to Ethernet cables as well. Although it may not be the best to affect a worthwhile shot. 

Try disconnecting your devices from the router and reconnecting them. Wait for each device to charge and connect to the network then reconnect them.


9. Run Network Troubleshooter in Your Settings

Most likely your computer has a feature that can help diagnose problems with your network. This feature is often called network troubleshooting and is available on Windows computers and there are ways to do this on a Mac.


– For Windows 10:

Click Start on the Dashboard and then click Settings. Select Network and Internet and then Status. Under Change your network settings select Network troubleshooter.


– For Mac: 

On your Mac select the Apple menu icon. Click Restart and then press and hold the D key while your Mac restarts. Continue to hold down the D key until the screen that displays a different language appears.


Choose a language and then Apple’s diagnostics will start automatically.


Once the diagnosis is complete he will list any problems that may occur. Note: (The reference code is for the Apple Support Team).


Hopefully, by performing some of the following steps your cable issues are gone. But with the complexity that can come with many different components working together the case may not be working yet. We contacted some installers to get there for a few rare reasons why your ethernet lan cable is not working.
