Tools you need for home ethernet wiring

We got all our network products, but you will also need some specialized tools to start with your home ethernet wiring:

  • Ethernet Crimping tool – if you are going to connect RJ45 plugs

Sale 3,006 Reviews TRENDnet Crimping Tool, Crimp, Cut, And Strip Tool, For Any Ethernet or Telephone Cable, Built-In Cutter And Stripper, 8P-RJ-45 And 6P-RJ-12, RJ-11, All Steel Construction, Black, TC-CT68 $17.99 −$3.67 $14.32 Check on Amazon


Ethernet Wall Sockets

So for the other end of the ethernet cables, we are going to need ethernet wall sockets. The wall sockets, in general, are different in the US than in the EU. In the US you can get wall sockets with removable keystone jacks. This will make installation a lot easier.

Sale 1,316 Reviews VCE Ethernet Wall Plate 1 Port (UL Listed), Cat6 Female to Female Wall Jack RJ45 Keystone Inline Coupler Wall Outlet, White (2 Pack) Cat6 ethernet wall sockets $9.99 −$1.50 $8.49 Check on Amazon

Because we are using solid wires, you will need keystone jacks that you can punch down, like these Cat6 keystone jacks on Amazon. For the EU you will need ethernet sockets like these on Amazon.

Surface Mounted Ethernet Sockets

You can’t always use a wall socket for your ethernet connection. For example, with your access point, you might want to use a surface-mounted socket. You can place these in a convenient location and then use a normal patch cable between the socket and access point.

Method 2: Ethernet over Powerline Adapters

Another way to get wired internet access in other

Another way to get wired internet access in other rooms of your home is through these super handy devices – powerline adapters. These devices plug into your electrical outlets and use the existing electric lines in your home to transmit data – how cool is that?!

They’re not a perfect replacement for a true Ethernet line but they will be faster and more reliable than a wireless connection. I use them in my home and have never considered going back to wireless.

Installation is also pretty easy. Just plug the powerline adapter into an outlet near your router and connect it to the router via an Ethernet cable. Then in the other room, plug the powerline adapter into an outlet near the device and connect it to the device with an Ethernet cable.

If you need to connect more devices you can simply get additional adapters and add them to the network. They will all transmit data to the adapter connected to your router. You’ll want to make sure that you’re plugging them into an outlet and not a power strip as doing so can cause problems.

These adapters usually come as a kit with two adapters and two Ethernet cables to connect them to your router / device. If you’re not sure where to start we recommend the TP-Link AV600 Powerline Ethernet Adapter.

Your experience may be different though depending on the wiring in your home, so make sure your purchase is refundable if they don’t work out for some reason.

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.

Which Network Ethernet Cable Should You Choose for the Your Home Ethernet Wiring?

From the passage above we know that the wired home network connection is based on Ethernet cable, next you’ll have to decide what type of cable you want to use.

Cat5e, Cat6 or Cat7 Network Ethernet Cable

There are Cat5e, Cat6, Cat7 Ethernet cables, among which Cat6 cable is highly recommended for its faster speed and cheaper price when compared with Cat5e and Cat7 cables. Wiring your house will take a long time and it’s always better to do it right the first time. It is suggested to calculate the cable length before purchasing in case of material waste and always keep in mind to make the cable extra longer than which you actually need.

UTP or STP Ethernet Cable

If you have made your decision on the cable, then you will have to consider which type of cable you need-UTP or STP? UTP stands for unshielded twisted pair while STP stands for shielded twisted pair. Shielded is much more expensive because it adds a layer of protection on the outside of the cables. For home use, the unshielded is completely fine.

Stranded or Solid Ethernet Cable

Next, there is the option of stranded or solid core wire. This basically means that the inside of your wire is made up either braided strands or one solid piece. What this comes down to is how much manuevering you will need to do with the wire. If you’re going to be fishing it through tight spaces, a solid piece of wire is much easier to move around in a tight space because it is rigid. The drawback to the solid core is that it is harder to connect to the wall outlet or plastic jack. Stranded wire is easier to connect to a wall outlet, but it’s pretty flimsy if you’re trying to push it through crevices.


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!
