Ethernet Port in Wall – All Your Questions Answered

You might not have seen an Ethernet port before if you’re unfamiliar with networking or have not had to connect a device using a cable. The good news is that you can quickly locate them on various electronic gadgets. Almost any modern electronic device has an Ethernet connector, from video game consoles like the Xbox and PlayStation to desktop and laptop computers, printers, modems, routers, and fax machines. See an example of an Ethernet port in the image below.

Key Takeaways

  • The Ethernet port in the wall is usually connected to a router or modem to access the internet.
  • To use an Ethernet port, you require an ethernet cable for connection.

It is possible to install an Ethernet jack or port into a wall. To set up a local area network, you’ll need ports (LANs). A standard Ethernet cable can be plugged into the socket, which resembles a large phone jack.

What Is the Ethernet Port in the Wall For?

Ethernet ports in the wall, often called LAN ports or network connections, are the physical connectors that allow electronic devices like PCs, servers, and game consoles to link up with one another and access the web. You’ll need at least two adapters, which you use to link your router and your device together with Ethernet cables and an electrical outlet (TV, games console, PC, or whatever it may be). In contrast to your wireless connection, Ethernet gives you a hardwired link between your device and your router.

Can You Install an Ethernet Port in the Wall?

It is possible to save money by installing an Ethernet jack on your own if you need one in your home. An Ethernet jack can be installed in minutes with the correct equipment and know-how. You can install an Ethernet port on the wall by following easy steps.

  • Locate an easily accessible spot on the wall. It’s preferable to pick a spot that doesn’t have any obstacles in the way of your Ethernet line and can accommodate its installation afterward.
  • Put a mark on the wall where you intend to install the jack.  You can use a pencil to mark; let us say ‘X.’
  • Locate the marker, center your mounting bracket above it, and draw inside the outline. Move the pencil lead along the inside edge to locate the network jack’s mounting bracket on the wall plate. Once you’re done, you’ll have a general outline to use as a guide when cutting the hole in the wall for the Port.
  • Turn off the power to all nearby outlets. To activate the outlet adjacent to which you will place your network jack, you need to go to the main breaker panel or electrical control box for your building and turn the switch for that outlet. Turning off the power supply eliminates any risk of electric shock.
  • Take a utility knife and carefully cut along the lines you drew. Lightly scoring the outline will provide clean and accurate lines. Repeat the process several times over each line, increasing the pressure. Your Ethernet jack’s wall plate will fit into a clean, smooth hole after a few passes, and the excess drywall will pop out.

How Much Does It Cost to Install Ethernet Port in Wall?

There is no specific cost for installing an Ethernet port on the wall. Professionals charge differently depending on the number of ports. The plugs are necessary for establishing a local area network. If you plan to install several ports, the cost will depend on the number of ports in your plan.

Does Ethernet Wall Jack Slow Speed?

No, the Ethernet wall jack does not slow speed unless the Port is faulty. However, your connection speed could be affected if your Ethernet cable is wrong or damaged. A broken cable or faulty Ethernet switch box will reduce your connection speed.

Ethernet Port In-Wall: How to Use It

The first step in using an Ethernet wall plug to access the Internet is to locate a free Ethernet port on your modem or router. Then, connect an Ethernet cable by inserting one end into the Port and another into the wall outlet that supports Ethernet. Start up your computer and launch a web browser once you’re online and ready to explore the World Wide Web.

Ethernet Port In-Wall Not Working

If your Ethernet wall jack is malfunctioning, the fault is probably with the wiring. To begin, examine the cords. Verify that all wires are securely fastened and that the plugs are inserted into the ports. 

New cables may be required if the issue persists. Verify the integrity of the Ethernet cable between the modem and your computer, and look for signs of damage to the Ethernet wall jack. Get it fixed by contacting your Internet service provider or an expert.

Ethernet Port in Wall Name

There’s a jack and a plug, known as 8P8C jacks and 8P8C plugs. However, the common name is a data jack, sometimes known as an RJ45 jack. 

Ethernet Port in Wall Is Too Small

People who depend on a constant and reliable internet connection often opt for Ethernet cables.

If an Ethernet cable doesn’t fit into one of your ports, you have a few options:

Alternate Port

You can try another if one Ethernet socket doesn’t fit the cable.


Some ports have extra doors installed in front of the Ethernet connector. The Ethernet port will have a minor glitch if you don’t open that door. If you want to connect an Ethernet cable, you’ll need to open the door and find the proper-sized connector.


The Ethernet port may have a pulled-down clip if there is no door covering the Port. Pulling down on the clip prevents the Ethernet cable or Port from being fully inserted. Still, you could experiment with angling the clip from its point. Typically, a fingernail will suffice for the purpose.

Connecting to the Network via Ethernet Adapters

Connecting the Ethernet port to the laptop can be done using either the USB-C or USB-A ports. In addition, the Ethernet adaptor can be used.

Swapping the Port With a Functioning One

If troubleshooting other possible causes fail, having the technician check the Port is your next bet. Professionals can easily replace the Port.

How to Test Ethernet Port In-Wall

Plug in a sniffer or Ethernet loopback adapter into the Port. Assuming the connector is functional, it will detect your Internet connection and display an appropriate light. If you don’t have the sniffer, follow the following easy steps:

  • Use an Ethernet cable to link your device directly to your TV or laptop. Launch a web browser or experiment with another online activity. The functionality of the Ethernet will be confirmed.
  • Plug your modem or router’s Ethernet wire into your Ethernet device’s WAN port.
  • Connect your laptop’s Ethernet to the switch’s “LAN 1” port.
  • To restart your modem or router, press the “reset” button. If it doesn’t have a power button, you can reboot it by removing the plug from the wall outlet and waiting a few seconds.
  • After the reboot, connect the Ethernet switch’s power adapter to a wall outlet.
  • Ensure that the Ethernet switch’s WAN and Lan 1 ports have green lights above them. Both lights are green for connectivity to be established.
  • Launch a browser to determine if you can access online resources.
  • If necessary, repeat the process with the “LAN 2.”

Ethernet Port in Wall vs. Phone Port

It is easy to confuse Ethernet and phone cables since they appear similar. The size of the plastic plugs at each end of the line is the main determining factor. When connecting to a telephone, you’ll need an RJ11 or RJ12 plug, but Ethernet cables require another type of plug: an RJ45. The difference between RJ11/four RJ12’s to six pins and RJ45’s eight pins is the size of the connector.


You would prefer Ethernet over WIFI as a gamer because of latency concerns. There need to be ethernet plugs strategically placed around the house so that we may set up a Wi-Fi Mesh network. The article has offered a solution if you don’t have preexisting ethernet cable wiring within your home. Simply follow the guide and have speedy internet access from your home.
