How To Run Ethernet Cable Through Exterior Wall in the right way

Can You Put an Ethernet Cable through an Exterior Wall?

It is safe, legal, and simple to run an ethernet cable into your home through an exterior wall. Before drilling, make sure to run the cable to an exterior box to provide internet connectivity.

  • Running an ethernet cable is a safe DIY task that can be performed without damaging your home.
  • An ethernet cable is extremely low voltage, making it safe for DIYers to install.
  • Check local building code to verify that ethernet installations are not regulated.

Because an ethernet cable is extremely low-voltage, most building codes do not significantly restrict running ethernet cable. This means it is often a DIY job you can do yourself. If you have any concerns about running an ethernet cable, check your local building code before you begin work.

Tips for Running an Ethernet Cable Through Wall

Read these tips below. You may need these while running the cable.

  • While running the ethernet cable, make sure there are not any HVAC lining in the cable path.
  • If your house wall has thermal insulation, then there may be jack installed inside your house. So, connect the cable through the non-insulated wall or the jack box.
  • If you worry about your exterior clapboard then, we suggest having it painted or sealed right after cabling. Drilling a small hole is not a big issue at all. If you hire a cable connector man, he will do the same thing.
  • Try to seal the hole after completing the cable connection task. In the time of raining, there can be a chance of water draining with the cable.
  • Though the best quality of ethernet is waterproof, you should make sure the cable remains UV protected.
  • Using silicone or slack to block the hole can be very beneficial. Slacking paint is a mixture of dirt and coal dust that you can use in the hole area. And the best thing about it is you can remove it easily whenever you need to change the cable or for any other issue.

What Ethernet Cable Should I Use For My Home Network Wiring?

In addition to knowing the tools you’ll be using when running Ethernet cable through walls, it is equally important that you settle on the ideal Ethernet cable.

This, as you’d expect, brings with it one question – what Ethernet cable should I use for my home network wiring? That said, it’s worth pointing out that Ethernet cables are generally rated in categories depending on speed and how fast they can transfer data over cable.

With Ethernet cables, you want to settle on one that offers the very best when it comes to both speed and quality. Ethernet cables such as Copper Clad Aluminium or CCA should be avoided at all costs.

They are known for many issues, such as getting hot and delivering less power. Opting for full bare copper cables when running Ethernet cable through walls is highly advised.

Patch Panel for Home Network

You could connect an RJ45 connector on a solid UTP cable, but it really isn’t recommended. Ethernet cables that are hanging loose don’t look nice, aren’t easy to work with, and finding the correct cable is harder. But even more important, UTP cables with solid wires are brittle and shouldn’t be bend too much.

Patch cables, that you use between your patch panel and switch, have stranded wires which makes them flexible and easier to bend (without breaking the wires).

So a far better option is to use a patch panel. Now, these patch panels don’t always need to be big and mounted in a rack. For a home network, there are also patch panels that can be wall-mounted and are a lot smaller.

There are a couple of options available on the market. It really depends on how many connections you have what the best option is. For up to 12 ethernet connections I really like to use these wall-mounted patch panels:

If you need more than 12 ports you can either use two of these or go for a 24 port patch panel and use a 1U mounting hinge.

Use Strategies to Protect the Wire From Catching Between Floors

Ethernet cable can catch between floors. So it would be best if you made the wire stay stable for continuous internet connection. You can use some strategies to protect the wire jammed between floors. Let’s see some helpful tips:

You can tape the end of the wire that you attach in the hold to the coathanger. Regular scotch tape is the perfect choice, but you face difficulty with this tap. So you can use the sticky tape that feed the cable challenging to remove.

Drill a hole straight down through the beam that serves as the header for the wall. Equip your electric drill with this 1-inch auger bit.

Use an electrical drill equipped with this ½-inch drill bit to drill a hole through the outside wall. At this point you’ll also want to chop a hole in the wall up the distribution room

One can run the wire and coat hanger in the newly drilled hole. If you pick the bottom to do this, you should drop down without hassle. Dropdown coat hangers in the spot and leave it hanging below. You can use hangers to push the wire quickly.

If the wire tip is poking in the wall end, pull it. It isn’t easy to keep the cable on hold. Then you can feed the wire in the hole and pull through three or five feet before getting to the next step. If you provide an extensive range of wire in the wall, remove the hanger. Now, you can run through the wire and install it.

Your Cable Into the Wall Feed your coaxial cable down through the opening you drilled. Feed carefully, feeling for any obstructions. it is also an honest idea to write down down the space of the opening you drilled from both corners of the wall. 

This may allow you to exactly locate the wire once you narrow a hole in the wall to feed it into the space below the attic

How Do You Pick the Best Ethernet Cables?

Choosing an Ethernet cable can be a time-consuming and challenging task. Moreover, there are different kinds of Ethernet cables in the market.

Therefore, it would help if you found the suitable cable which meets your requirements. The followings are some tips on how to choose the Ethernet cable.

Decide whether you need to purchase the pre-made Ethernet cable or manufacture your own. You can buy the Ethernet cable and construct them to the exact length you want them by attaching the Ethernet cable connection at all ends of the wires.

  • You should consider the environment where you install the Ethernet cable. Some Ethernet cable is waterproof, and many cables are not waterproof designed for the indoor purposes in the dry atmosphere. Decide where you need to install the Ethernet cable inside or outside. You will need to purchase the high-quality Ethernet cable which suits your atmosphere.
  • If you connect the desktop or other devices to the network hub, you need the straight-through cable. Without a modem to communicate with two computers directly, you use a null-modem Ethernet cable.
  • The speed is another aspect to bear in mind when choosing an Ethernet cable. You should go with the most excellent cable which suitable for your budget. It would be best if you designed the infrastructure to reduce the length of Ethernet cable wherever it is possible. Cat6a offers quick performance, but it is too costly than other Ethernet cables.

Conclusion

There is no denying that wired connections have their benefits, but in order to enjoy them, you’ll need to properly wire your connections.

One way of doing this is by running Ethernet cable through walls. We hope that after reading this post, you’ll be able to properly run Ethernet cable through walls even without the services of a professional!

How Far Can You Run Ethernet Cable from Your Router?

Ethernet cables are designed to sustain a run of no more than 328 feet (100 meters). Cable runs greater than 328 feet will cause the signal to deteriorate, leading to nonfunctional or poor internet access.

  • Maximum functional length of ethernet cable is 328 feet (100 meters).
  • Running cable past maximum length leads to signal deterioration.
  • Plan your install to ensure your cable is less than 328 feet.

When planning to install an ethernet cable through an exterior wall, make sure you are not running more than 328 feet of cable. Attempt to make the shortest useful route from the exterior box to an interior wall jack.

Testing your Home Ethernet Wiring

After you have pulled and connected all the ethernet cables it’s time to test them. Now there are two ways to test a cable, using a cable tester (the best way) or with a network device (notebook and switch).

You might think the fastest way is to simply connect your notebook on one end and path the other into a switch. If you can access the internet then the cable is fine. Well almost. The problem with ethernet cables is that they also work if only 4 wires are connected correctly.

The blue and brown wires are only used with 1Gbit network connections. So in theory, when the orange and green wires are connected correctly, you can get a network connection. But only with a network speed of 100Mbit.

Cables testers

A cable tester will test each individual wire in the ethernet cable. This is the best way to check if your ethernet cables connect correctly and don’t have any faults in them.

Each wire is indicated by a light on the cable tester. If the light doesn’t light up, then you have a faulty connection.

The best solution is then the cut the keystone jacket or RJ45 plug off and start over.
