Inspect your property for extant ethernet routes before trying to run an ethernet cable through an external wall. You might be able to redirect an existing network to provide Ethernet interconnection where you need it.

But how do you run Ethernet cable through walls? Poke a hole through an external wall if no existing facilities operate in your home. Digging through electric cables, HVAC ducts, or plumbing should be avoided.

After that, connect the ethernet cable to the preferred destination. Eventually, use silicone caulk to wrap the hole around the ethernet cable to thwart water infiltration.

In this article, I will walk you through how to run ethernet cable through walls, step-by-step, even if you’ve never done it before!

Let’s get started!

How Far Would an Ethernet Cable be Run From Your Router?

Ethernet systems are designed to have a maximum length of 328 feet (100 meters). Cable runs of more than 328 feet will degrade the signal, resulting in malfunctioning or poor web access.

Ethernet cable has a maximum functional length of 328 feet (100 meters). Extending the cable beyond its maximum length degrades the signal. You want to plan your installation so that your cable is no longer than 328 feet.

When installing an ethernet cable through an external wall, make sure not to run more than 328 feet of cable. Make attempts to find the shortest practical path between the exterior box and an interior wall jack.

Preparing For Your Home Network Wiring

You should begin with a plan, just as you would with any other project. We need to know where we would like our wired ethernet ties to be and where they will meet and how to get there.

We’ve divided the planning process into two steps:

  • Create a simple floor plan for your home: This is extremely useful for picturing all of the wired connectivity.
  • Determine where the ethernet connections are: Keep in mind that as children grow older, they may acquire a computer or a game console for their room. Consider a location for a network printer, and don’t forget about the access points.
  • Where should the domain controller and switch be placed?: If it is more advantageous, you can position a switch on every floor, or you could operate all the connectors in one spot. I prefer to have all connectivity in one location so that you can use a more significant switch or fully exploit the switches.
  • What method will you use to run the cable?: The attic and crawl space are excellent for running cables throughout your home.
  • How many ethernet ports are there per location?: It is strongly advised to have two ethernet sockets per location. UTP cables are inexpensive, and the incremental charge for an excess ethernet port is negligible. However, introducing one later will require more work and, most likely, money.

Tools Required to Run Ethernet Cable Through Wall Surfaces

The tools involved in running an Ethernet cable through walls are determined by various variables, such as the walls, your home, and coverage. Even so, some tools are essential, and they are as follows:

  • Ethernet Crimping Tool
  • Punch Down Tool
  • Drywall Saw
  • Pointed Hand Saw
  • Paddle Bit
  • Fish Tape
  • Stud Finder
  • Label Marker

Which Ethernet Cable Should I Choose for My Home Router?

Along with recognizing the equipment you’ll be using when operating Ethernet cable through walls, and you must choose the best Ethernet cable.

As you might expect, this raises one question: which Ethernet cable should I use for my local network circuitry? It’s worth noting that Ethernet cables are customarily classified based on their speed and ability to send information over cable.

When it relates to Ethernet cables, you should choose one that provides the best performance and accuracy. Copper Clad Aluminium (CCA) Ethernet cables must be avoided like the plague.

They are notorious for various issues, including overheating and providing less energy. When operating Ethernet cables through walls, it is strongly advised to use replete plain copper cables.

How to Run Ethernet Cable Through Walls

Now that you’ve got it all in place, it’s time to launch your Ethernet cable via your walls. This leads us to the first step.

Step 1: Establish a Radius Server

Any venture that involves running Ethernet cable via walls begins with creating or constructing a distribution hub. Turning off your apartment’s power source while constructing or establishing your core router is best.

This way, you’ll know you’re safe when digging through walls to make space for the distribution hub.

Step 2: Make Ethernet Cable Openings

After installing your distribution point, the next stage is to poke a hole in your Ethernet cable. Based on which floor you’re operating on, you’ll need to bore either the top or bottom roof plate. When you’re finished, make a hole in your cellar.

Ascend to a vantage point explicitly above your distribution box. Once you’ve found this location, cut a hole through the bottom of the base. When operating with attics, remember that most have double plates, so you may have to drill through much more than one wooden block.

Step 3: Identify Your Ethernet Cables

If you intend to run Ethernet cable through multiple walls, you must label them as per the apartments where the walls are located. You can have one branded “bedroom,” “living room,” or even “office” if you intend to work from home.

Once your Ethernet cables have been appropriately labeled, begin running them through the wall into the loft space. If you do it properly, your Ethernet cable(s) should appear ideally in the outlet holes you developed previously.

If your Ethernet cable(s) are visible, immediately pull them to the required lengths to finish the process of having to run the Ethernet cable through walls.

Related Questions

Is it worthwhile to run an Ethernet cable through the walls?

You might have to run the cable through the ceiling or wall at a certain point. Ensure that the cable does not contact the ceiling tiles and that it is not run over by electric wiring, water systems, or any other pipework, as this is unsafe and may fail evaluation. No data cables should be run underground.

Does Ethernet enhance the value of a building?

A home that has been meticulously wired for Ethernet not only provides your clients with higher bandwidth speeds, more consistent connection, and increased home security, but it can also boost the home’s value. Wires, ports, and switches should preferably be installed during the building phase.


There is no disputing that ethernet cables have advantages, but your cables must be appropriately tethered to appreciate them.

One method is to run an Ethernet cable through the walls. After reading this article, we believe that you will be able to run Ethernet cables through walls without the assistance of a professional!

This guide should help get you launched on your household ethernet creation and implementation. Purchase high-quality cables and keystone jacks. Keep in mind that substituting the ethernet cables is a significant undertaking.
