In recent years, wireless connectivity has become the go-to networking solution for a lot of people, thanks to its relative simplicity and ease of use. That being said, there is still a substantial amount of people who might prefer a hard-wired solution due to paranoia surrounding wireless networks, home bandwidth-usage, or file-sharing.

Having a wired home network provides you with a private, high-speed network, enabling Internet connectivity, as well as file-sharing, online gaming, streaming, and so much more.

Of course, getting a hard-wired network up and running can be quite the task, and it’s all too easy to get something wrong along the way if you don’t know what you’re doing. Luckily, we do, and in this article, we’re going to show you how to run Ethernet cable through walls quickly and easily (and without damaging your walls).

Step One – Initial Considerations

Before you start, there are a few considerations that need to be made.

Which rooms do you want wired?

We can’t answer this one for you, but we can suggest – at least – that you wire all the rooms which contain devices that you need to be wired, such as a TV or home video game console.

How many ports do you want?

This next consideration follows on nicely from the first and will most likely be determined by the number of devices in each of your chosen locations (rooms). For example, you may have a TV, a network-connected Blu-ray player, and a video game console all in one room. This means that you’ll want at least three ports, but depending on the wall plates you have installed, this number can vary.

What is a good location for distribution?

You’ll want to pick a location that’s centralized enough to be able to reach all of the rooms you want connected. An attic is a great choice here, but really, anywhere will do so long as your Ethernet cables can actually reach it.

What path should the cables take?

This will probably be the most challenging consideration, especially if your home has multiple floors. If that’s the case, you’ll need to get creative. The purpose of this consideration is essentially to give you an idea (and possibly, a plan) of the route your cables will take from your distribution center to each of the rooms you want to be wired. If you can, mark this route on a floor plan, or indeed, on the walls and floors of your house itself.

Step Two – Gather Your Tools and Materials

Now that the initial preparation phase is over, the last step you need to take before you can start laying down some wires is to gather the tools and materials you may need.


  • Ethernet cable crimping tool
  • Drill
  • Paddle bit or hole saw
  • Pointed hand saw
  • Fish tape
  • Pencil
  • Ruler
  • Marker


Step Three – Mount the Wall Plates

In the rooms you’ve decided upon, you’ll now need to decide where to mount the new wall plates. You will need to draw lines on the wall in order to fit the new plates, so grab your pencil and ruler and simply trace the shape of your wall plates.

Now use your hand saw to cut out this shape that you’ve measured. It should be able to pierce the drywall. With the hole cut, you may now place the single gang box into the wall and clamp it in place with screws.

Lastly, you will also need to cut a small hole which the plastic grommet will fit through, both here and in your distribution center.

Repeat this process for each of the rooms you have decided upon.

Step Four – Run Your Ethernet Cables

With each room prepared, you can now start laying down your cables. You will need to measure them beforehand, however, which shouldn’t take long. An easy method is to run a length of cable from your distribution center to one of the rooms you have selected and measure this distance with string. You can then cut a few more cables of the same length, depending on how many connections you want per room.

Actually, laying the cables down is pretty easy, thanks to all the preparation you’ve done already. It’s simply a matter of getting from point A to point B.

Step Five – Test Your Connection

You’re almost there, but before we let you go, be sure to test your connections. If something’s wrong, it’s best to know it before you put your tools away.

Final Thoughts

And there you have it! That’s pretty much all you need to know about running your Ethernet cable through walls without damaging your walls or your Ethernet cable. There is no need to call a professional who will charge you more money than you should have to spend. With a little preparation and some fine handiwork, you’ll have a hard-wired home network up and running in no time.
