How To Fix Ethernet Port On Motherboard

If you have been having problems with the Ethernet connection on your motherboard not functioning, you are not the only one having these problems.

When a port on your motherboard is malfunctioning, the first thing you should do is examine the state of the Ethernet connection. Install the drivers for the motherboard if the issue is not caused by the cable. Additionally, check the BIOS settings to see whether your local area network (LAN) is active. Look for the port pins and raise them if you find any. If none of these solutions work, your best bet is to invest on a USB Ethernet adaptor.

Can an Ethernet Port Go Bad?

A computer has what’s known as an Ethernet port, which is an aperture in which an Ethernet cable may be plugged in. It is used to connect wired network devices to a local area network that uses Ethernet. Typically, you may find it either on the back or on the side of your smartphone.

A router, for instance, often contains a number of ports to accommodate a variety of wired devices that are connected to a network. In contrast to a MacBook, which lacks a built-in Ethernet connection, laptops are equipped with one by default. Instead, it features an Ethernet adaptor that is USB-based.

At least one Ethernet port is standard on today’s widely used broadband routers. Connecting a broadband modem, which may be linked to the Internet as well as other devices that are network-connected, to a router that has a WAN port is necessary.

A WAN port and four extra Ethernet ports are often included in the configuration of wireless routers.

The difference between a phone cable and an Ethernet port is that the latter is somewhat wider than the former. It is physically impossible to connect the Ethernet cable to the phone port in the correct manner due to the design of the port. It simplifies the process of connecting the wires. Because of this, there is less of a chance that you will connect it to the incorrect port.

If you have Ethernet in your house, you are probably aware that it is a great investment that comes with a variety of advantages. There is a good chance that you have, at some point in the past, run into issues with Ethernet connections, such as breakage or deterioration. Whenever you run into problems like these, the simplest solution is to just purchase a new cable. On the other hand, there are situations when the issue is not with your Ethernet cable but rather the port.

Yes, an Ethernet port may develop problems; there are numerous potential causes for this, some of which I will discuss in the following paragraphs. Electronic components that are static-sensitive and prone to failure include ports, particularly switch ports located on the panel.

If you are having issues connecting to the internet on your computer, the Ethernet port is typically the first place you should investigate since it is possible for it to be the root of the issue.

Errors such as “Network cable unplugged” are often caused by faulty Ethernet ports. If you have recently moved your computer or laptop, which may easily relocate a cable from the Ethernet port or, in rare situations, remove the Ethernet card from its spot on the motherboard, you may get similar error messages. This is particularly true if you have recently moved your computer or laptop.

In the following paragraphs, I will go into more detail regarding this topic.

Why is Your Ethernet Port Not Working?

There are several potential causes for why your Ethernet port is malfunctioning despite the fact that your internet connection is OK. Sometimes the problem is inside the cable as a result of it breaking or becoming damaged. The tension on the cable that is used to provide force to the port is the primary cause of the failure of the connections that are found on the motherboard, which occurs very often.

The LAN port, along with the other connectors on the motherboard, is secured to the circuit board by soldered connections. These solder spots may become brittle or shatter under the pressure of external cable tension, which can lead to connection failures that are either intermittent or total.

You have a few options to repair the damaged port, and they vary depending on whether you use a desktop computer or a laptop.
Device drivers, or more particularly the installation of an incorrect version of device drivers, are most likely to blame for your Ethernet port’s inability to function properly.

The incompatibility of individual pieces of hardware is the second most typical reason why such a problem arises. It is probable that the problem is with the compatibility of your LAN card and motherboard, which would explain why it is not functioning properly.

It’s also possible that the issue is caused by a faulty LAN Ethernet card or Gigabyte’s hardware in general. Your port might sustain damage from a lightning strike as well.
When you place your finger below the Ethernet cable and raise it slightly, you could occasionally discover that it formed the connection. This is an indication that the pins in the Ethernet port are defective and bent, and they do not create connection very effectively.

Examining the port pins is the best way to determine whether or not they are the source of the issue. There ought to be eight pins in all. In the event that some of them are not increased to the same degree as others, this indicates that it is the reason of intermittent connection issues.

The following steps may be taken by you in order to determine whether or not your port is now active:

  • Establish a connection between the network port on your computer and the wall port using a blue network cable.
  • Start up your computer and log in.

If you have a Windows computer, do the following:

  • To access the rear of your PC, please make your way there.
  • Examine the area around the blue network cable for a light that is either orange or green and steady. If your network port is currently being used, you will see that it is lit up.

On an Apple computer, do this:

  • Apple should be chosen from the option that drops down.
  • From the menu that drops down, choose the System Preferences option.
  • Choose the Network option. On the Ethernet connection, there ought to be a green signal that reads Connected in there somewhere.

This is the quickest and most convenient method for determining whether or not there is an issue with your port. In the event that there is a problem, you are able to work on it and test out some of the remedies that I will discuss in the next section.

How Do You Fix a Dead Ethernet Port?

If you run into problems with the port, there is no need for alarm. Check to make sure that the drivers are installed before you go and spend money on a new port for the motherboard.

You need to ensure that they are installed correctly. If you want to make sure that the drivers on your computer are up to date, try using a different LAN cable that is functional.

After that, do ping tests by utilising the IP address of your router in conjunction with websites like Google. In the event that the issue is still present, disable all firewalls and security software (it might block your port). You may do so by navigating to the Device Manager on your computer.

In addition to that, you may proceed as follows:

  • Check that the Ethernet port is clean and clear of lint and dust.
  • Examine the condition of the Ethernet wires to ensure that they are in excellent working order. You could test the cord with a different computer or with a new set of cables if none of those options works.
  • Check to see whether the port on the switch or router is working properly. You might try another port.
  • Check the BIOS to check if it has the LAN option activated.
  • Remove the power cord from your computer, and then restart it after a few minutes. The next step is to go to the SmartLAN option inside the BIOS once you have turned on your computer and plugged it in.
  • Erase the CMOS and change the settings in the BIOS.

Pins were one of the potential causes of the malfunctioning port, as I noted before. In order to repair it, you will need to use some smaller tools to raise the pins. After you have finished doing that, you should connect in your Ethernet wire. The connection has been restored, as shown by the presence of a green indicator light, and there is activity taking place at the port.

Alternately, you may replace the Ethernet port on your device; although, to tell you the truth, doing so would be a waste of money. On the other hand, there are some low-cost solutions to the difficulty you’re having. You may convert an underused USB port into an Ethernet port by purchasing a low-cost adaptor that combines USB and Ethernet.
It is not need to do any installation or configuration steps in order to utilise this adapter. Simply plug it in and put it to use; that is all that is required of you.

If your laptop is not too old and has at least one USB port that is version 3.0 or above, you could look on Amazon for one of the USB 3.0 Gigabit Ethernet adapters. They are simple to use, so you won’t waste any time learning how to utilise them. Some adapters even come equipped with supplemental USB 3.0 ports, allowing you to connect even more USB devices to your laptop. This is the most effective course of action.

Why did my Ethernet port stopped working?

It might be a faulty cable, a loose connection, a network card, an outmoded driver, or something else entirely. Both a problem with the hardware and a problem with the software might be the root of the issue. Therefore, we will need to try a variety of solutions, including not just software but also hardware issues, in order to fix the Ethernet troubles that we are experiencing.

Is my motherboard Ethernet port broken?

Errors such as “Network cable unplugged” are often caused by faulty Ethernet ports. If you have recently moved your computer or laptop, which may easily relocate a cable from the Ethernet port or, in rare situations, remove the Ethernet card from its spot on the motherboard, you may get similar error messages. This is particularly true if you have recently moved your computer or laptop.

Can a Ethernet port go bad?

Even though Ethernet is a very dependable and long-lasting technology, cables may get damaged over time and from normal wear and tear (especially if you move them around). When Ethernet cable is run through the walls of your house, this problem becomes much more challenging.

How do I know if my Ethernet port is broken?

Check the LED indicators on the equipment after following the Ethernet wire from your computer to the device where it ends, which might be a hub, router, or switch. When there is an issue with the connection, you should look for a solid green light rather than a flashing green or amber light. A solid green light indicates a good connection.


Ports, just like Ethernet cables, are susceptible to malfunctioning and eventually dying. Fortunately, there is a way out of this predicament. As a result, I have high hopes that you will take some of my advice to heart and fix the port instead of shelling out cash for a new.

There are usually inexpensive USB Ethernet adapters available for purchase. Because inserting the cable incorrectly or with too much force might result in the port being damaged, I also advise you to exercise caution while doing so.
