How to Run Ethernet Cables Through Walls

Ethernal Cable

Running Ethernet cables through walls allows for a cleaner, more organized setup, reducing clutter from your living or workspace.

It may seem like a daunting task, but with the right tools and guidance, you can undertake this project with relative ease. This guide will walk you through the process, giving you the confidence to enhance your internet setup by hiding those unsightly cables.

Necessary Materials for Wiring Your Home

To pull off this project successfully, you’ll need a set of essential tools and materials. These include an Ethernet cable of sufficient length, a stud finder for locating the wall studs, a drill with various-sized bits for creating holes, and a fish tape tool for guiding the cable through the wall.

Additionally, wall plates and RJ45 connectors will be required for a neat and professional installation. Personal protective equipment such as gloves and safety goggles are also recommended to ensure your safety during the project.

Increasing Your Internet Speed

Ethernet cables play a crucial role in boosting your internet speed. Unlike Wi-Fi which can be prone to interference and signal loss, Ethernet cables provide a direct, wired connection resulting in consistent and fast internet speeds.

This is especially important for data-intensive activities such as online gaming, streaming high-definition content, or for those working from home where a stable and fast connection is a must.

Therefore, investing in running Ethernet cables through your walls can greatly improve your online experiences, increasing productivity and reducing frustration with slow or unreliable Wi-Fi connections.

Preparing the Walls – Removing Obstacles

Before you begin the process of running your Ethernet cables, it’s crucial to prepare the walls by removing any potential obstacles. This includes insulation, drywall, and studs. Use your stud finder to locate any studs within the walls; these could obstruct the path of your Ethernet cable.


Once located, carefully create a pathway using a drill with an appropriate-sized bit. For insulation, try to navigate around it when possible to avoid unnecessary removal or damage. When dealing with drywall, handle it with care to prevent any substantial damage.

Small holes for the Ethernet cables can be patched up later for a neat look. Remember, preparation is key to a successful installation; taking the time to properly prepare your walls will make the rest of the process smoother and more efficient.

Making a Plan

Before you start drilling holes or maneuvering cables, it’s prudent to chart out a clear and optimized route for your Ethernet cable.

Begin by identifying the source of your internet connection and the device(s) you wish to connect.

The route should be the most direct, but practical, path between these points. Avoid routes that would require the cable to bend sharply or go through areas of high heat or moisture, as these conditions can degrade the cable over time.

Use a tape measure to record the distance between the points to ensure your Ethernet cable is of sufficient length.

Sketch a diagram of the route if necessary, marking any potential obstacles identified by the stud finder. This plan will serve as a roadmap for your installation process, saving you time and potential mistakes.

Drilling Holes and Running Cables

Now comes the step of drilling holes and running your Ethernet cable. Begin by using your drill to create holes at the designated points on your planned route – one at the source of your internet connection and others at each endpoint. Ensure these holes are slightly larger than your Ethernet cable to facilitate easy threading.


Before you start running the cable, double-check for any obstructions such as pipes, wires, or ductwork in the wall that could be damaged during the drilling process. Use a flashlight to peer into the holes and ensure the path is clear.

Next, attach the end of your Ethernet cable to the fish tape. Use this tool to guide the cable through the holes and along the planned path within your wall.

Be careful not to pull too hard or too quickly to prevent damaging the cable. Once the cable has reached the endpoint, pull it through the hole, ensuring there is enough slack for easy connection to your device.

Repeat this process for any additional cables or endpoints. Remember, patience and care are crucial at this stage to ensure a successful, tidy, and professional-looking installation.

Testing and Troubleshooting

After successfully running your Ethernet cables through the walls and connecting to your devices, the next crucial step is testing and troubleshooting the setup.

Start by connecting your devices to the Ethernet cables and power them on. Check if your devices recognize the wired connection and if they are able to access the internet.

A straightforward way to test this is by running an online speed test or simply browsing the web to ensure the connectivity is smooth.

In case of any issues, common troubleshooting steps include ensuring that your cable connections are secure, both at the device and the wall plate.

If connections are secure and you still face issues, try using a different Ethernet cable to ascertain if the problem lies with the cable itself.

If you’ve run multiple cables, check each one individually to pinpoint any potential problem areas. Ethernet cable testers are also available on the market, which can confirm whether the signal is transmitting properly through your cable.

Remember, troubleshooting often involves a process of elimination, so patience is key. With careful testing and troubleshooting, you can ensure a stable, high-speed Ethernet connection for all your devices, enhancing your internet experience dramatically.


Running Ethernet cables through your walls may seem daunting, but with careful preparation and precise execution, it’s a task that can reap significant benefits for your home internet experience.

By following the steps outlined in this guide, you can enhance your connection, reduce the likelihood of signal interference, and ensure stable, high-speed internet for your data-intensive activities.

Do remember, that safety comes first, so be mindful of potential obstacles and use the right tools. Finally, don’t forget to test and troubleshoot your connections. With patience and a methodical approach, you’ll be on your way to an optimized home network in no time.
