Ethernet Port In Wall: All You Need To Know

Ethernet Port In Wall - All You Need To Know

Have you ever found yourself needing to plug something into the internet but not having any Ethernet ports available? If so, then you’re probably in need of an Ethernet wall port.

An Ethernet wall port is a device that allows you to connect your devices directly to your network using an RJ-45 cable. It provides a secure and reliable connection for all of your home or office networking needs.

With an Ethernet wall port, you can easily extend the range of your existing wired network without having to install additional cabling or hardware.

This makes it perfect for those who have limited space and don’t want to run long cables throughout their home or office.

So if you need more access points, look no further than the versatile and convenient Ethernet wall port!

What Is the Ethernet Port in the Wall For? What does it do?

It provides a reliable, fast connection and offers many advantages over Wi-Fi, including improved security and faster speeds. In this blog post, we will go over the concept of an Ethernet wall port and how it works. 

How an Ethernet Wall Port Works 

An Ethernet wall port is installed in the walls of your home or office to provide an easy way for you to plug in a network cable for connecting to the internet.

The port consists of two RJ45 connectors—one on the wall and one on the end of the cable—which is then connected via an 8-pin connector. 

The main advantage of using an Ethernet wall port is that it provides a much more secure connection than Wi-Fi.




This is because data transmitted over a wired connection cannot be accessed by anyone outside of your home or business as long as all ports are properly secured with passwords and other security measures.

Additionally, because there is no interference from other devices like phones or microwaves, wired connections offer faster speeds than wireless networks. 

Benefits of Using An Ethernet Wall Port – is it worth wiring up your house?

Yes for sure!

Ethernet wall ports can be beneficial for both homes and businesses alike, providing reliable internet access without any compromise on speed or security.

They also require minimal setup, which makes them ideal for those who want to quickly connect their computers or other devices without having to tinker around with settings.

Finally, because they use cables instead of radio waves, they don’t suffer from any signal interference issues like Wi-Fi connections do. 

Can you install an Ethernet port in the wall?

Sure! You can save a few bucks and do it yourself!

This project is best suited for someone with intermediate experience and knowledge of electrical work, but it is not impossible for those who are new to this kind of project.

With the right tools and instruction, installing an Ethernet port in the wall can be both cost-effective and rewarding. Here’s a step-by-step guide on how to do just that! 

Gather Supplies

Before starting any electrical work, make sure you are properly prepared by gathering all of the necessary supplies.

You will need an Ethernet connector, wire strippers, an electrical tester, wire cutters or scissors, a drill with bits and screws (or anchor bolts), and a power outlet box.

Make sure you have all of these items before beginning the installation process. 




Cut Hole & Secure Outlet Box

Once you have gathered all of your supplies, find where on the wall you want to install your Ethernet port and mark it with a pencil or marker.

Then, use a drill bit slightly smaller than the outlet box to create a hole in that spot on the wall.

Finally, insert your outlet box into this hole and secure it with screws or anchor bolts as needed.  

Connect Wiring & Test Connection

Next, connect your wiring from your router or modem to the back of your outlet box using either Cat5e or Cat6 cables (depending on what type of connection you prefer).

Once connected, use an electrical tester to make sure that there are no live wires present before proceeding further with the installation. 

Connect Outlet Box & Secure Cover Plate

Now that everything is connected correctly and double-checked for safety measures, insert your Ethernet connector into place inside of your outlet box and secure it into place with screws if needed; then attach the cover plate so nothing protrudes from the wall once installed completely. 

How much does it cost to install an Ethernet port in the wall?

The first thing to consider when determining the cost of installing an Ethernet port in your wall is the type of materials you’ll need.

For example, if you’re using standard Cat 5e cabling, you can expect to pay anywhere from $0.50-$1 per foot for the basic wiring materials.

If you decide to upgrade to more advanced cabling, such as Cat 6 or Cat 7, then your costs will be higher.


In addition to the wiring materials, you’ll also need a special Ethernet jack and wall plate. Depending on the type of jack and plate you choose, these can range from $2-$15 per piece.

You should also factor in the cost of hiring an electrician or IT professional to install the port; this could cost anywhere from $50-$100 depending on where you live and how long it takes them to complete the job. 

Finally, if there is any drywall or plaster work that needs to be done before installing your new Ethernet port (e.g., patching up any holes created during installation), then this could add additional costs to your total bill.

Again, these costs will vary depending on where you live and who is doing the work for you; however, they can range anywhere from $50-$200 on average. 

Does the Ethernet wall jack slow speed?

As with any electronic device, several factors can affect the speed of an Ethernet wall jack, such as signal interference, the quality of the cabling, and the type of data being sent.

Signal Interference 

The most common cause of slow speeds in an Ethernet wall jack is signal interference.

This interference can come from a variety of sources, including electrical devices like microwaves, cordless phones, and fluorescent lighting fixtures.




To reduce signal interference, it’s important to keep your cables away from these sources as much as possible.

Additionally, using a shielded cable that has extra shielding around it may help reduce the amount of interference picked up by your cords. 

Cabling Quality 

The quality of the cabling you use for your Ethernet wall jack also plays an important role in determining its speed.

Cables that are made from inferior materials will be prone to wear and tear over time, resulting in slower speeds due to decreased signal strength.

It’s best to invest in good-quality cables so that you have fewer problems with slow speeds in the long run. 




Type of Data Being Sent 

The type of data being sent through your Ethernet wall jack also plays a role in determining its speed.

For instance, if you’re sending large files or streaming videos over your network connection, it will take longer than if you were just sending text messages or browsing websites.

This is because larger files require more data to be transferred at once which takes more time than smaller ones do.

Therefore, it’s important to consider what kind of data you’ll be sending over your network connection before investing in an Ethernet wall jack. 

How Ethernet Wall Ports Can Optimize Your Network Range 

The most obvious advantage of using an Ethernet wall port is that it eliminates the need for extra cabling and hardware.

Instead of having to run cables from one device to another, all you need is a single cable connected to the wall port. This makes it much easier and faster to expand your network range without having to purchase additional equipment or hire technicians.

You can use your ethernet ports to interconnect WiFi mesh systems and WiFi boosters through an ethernet backhaul, without the need to connect them wirelessly thereby boosting their network coverage and speeds over WiFi.


RJ45 cable


Is an Ethernet cable faster than WiFi?

Yes, an Ethernet cable is indeed faster than WiFi. Here’s why:

Ethernet cables are physical wires that connect directly from your modem or router to your computer or another device. This makes them ideal for gaming setups, as they provide a reliable connection that won’t drop out mid-game.

They also offer much faster speeds than WiFi can provide—up to 10 Gbps (gigabits per second). However, this speed can vary depending on the type of cable being used, so it’s important to research what type of cable will work best for your needs before making a purchase.




WiFi connections on the other hand use radio waves to transmit data from one device to another wirelessly. This makes them much more convenient than wired connections since there’s no need for extra hardware or messy cabling.

However, due to the nature of radio waves, connection speeds tend to be slower than those provided by wired connections—typically only up to 1 Gbps (gigabit per second).

Additionally, since these signals travel through walls and other obstacles that can interfere with their strength, wireless networks can be unreliable if not properly configured and maintained.

This can be a very frustrating problem, but there are several methods you can use to troubleshoot and fix it. Read on to learn more about how to troubleshoot your in-wall ethernet port. 

Ethernet Port In-Wall Not Working

Check for Power 

The first thing you should do when troubleshooting an in-wall ethernet port is to make sure that it has power. If your in-wall ethernet port is not working, it could be because it isn’t receiving any power.

Check the breaker box or surge protector if necessary to make sure that the power is on and that the device is plugged into the wall properly.

Also, check if there are any loose cables or wires that may have gotten disconnected from the port itself. 

Check Connections 




If the power is on and everything looks good with the wiring, then it may be time to check your connections. Make sure all of your cables are securely connected and that they are not damaged in any way.

You may also want to try unplugging and plugging back in each of your cables one at a time just to double-check their connection status.

Additionally, you should make sure that the ports themselves are secure and not loose or damaged in any way. 

Check Network Settings 

If all of your connections appear to be secure, then you may need to take a look at your network settings as well.

Make sure that all of your devices are connected to the same network and that they all have access to the same internet connection as well.

If everything looks like it should be good here, then you may want to try resetting your router or modem just in case something was changed accidentally within its settings menu.

With some patience and effort, you should have no trouble getting things fixed up, if not, you may need a professional network consultant.

How to Test An Ethernet Port In Wall Connection?

Testing an in-wall Ethernet port is a simple procedure that can help determine if your connection is working properly.

Step 1: Connect Your Cables 

The first step to testing an Ethernet port in-wall is to connect the cables correctly. You’ll need two RJ45 connectors, one for each end of the cable.

Make sure both ends are securely connected and then attach them to the ports on either side of the wall. When connecting the cables, ensure that the colored wires match up with each other—orange with orange, green with green, etc.

This ensures that your data will be transferred properly between devices on either side of the wall. 

Check Network Settings 

Once you have connected your cables, it’s time to check your network settings. Open up your network settings and make sure that all of your IP addresses are set correctly and that they are all within range of each other.

Also, make sure that there aren’t any conflicts between any of your devices or networks—this could cause issues when trying to establish a connection later on down the line. 

Test Your Connection 

Now it’s time to test your connection!

Use an internet-based tool such as a ping test or traceroute to send out packets from one device to another across the network connection you just created.

If everything is set up correctly, these packets should be able to travel back and forth without any interruption or latency issues.

If something does go wrong during this test, it could indicate issues with either the cable or hardware itself and you’ll need to troubleshoot further before proceeding with setup. 

What does the color of the lights on the Ethernet Port mean?




Ethernet ports have several lights which may be amber, yellow or green. The purpose of these lights is to indicate whether the device is properly connected to another device and working correctly.

Let’s break down each of these color codes and their meanings. 


Amber means that there is a connection but it is not active, or data transmission has stopped. This could indicate a problem with the cable or even a software issue.

If you see this light flashing, it likely means that either no connection has been made yet or there is an issue with the hardware/software compatibility.  


A yellow light usually indicates a slow connection or low bandwidth usage. This could be caused by too many devices connected to one network or insufficient network resources for all connections at once.

It can also mean that the current connection speed is not fast enough for certain applications such as video streaming or gaming. 


A green light indicates an active internet connection and data transfer taking place between two devices through an ethernet cable.

It also indicates that both devices are compatible with each other and they have successfully established a connection over the network.  

Does an Ethernet cable have to be plugged into a router?

Yes! Even to get your Wi-Fi network up and running, it’s necessary to take a step back in time! A trusty Ethernet cable will help you lay the groundwork for all future wireless connections.

Once everything is configured, just unplug the cord – no more strings attached!

What is the internet port in the wall called?

The internet port in the wall is often referred to as an Ethernet port or RJ-45 port. This is because it contains eight pins and looks like a large telephone jack!

Essentially acting as a gateway from your device to your internet connection provider.
