When drilling the hole, determine where you want to run the wire. If you want to expand an ethernet connection into a room, you should drill from the inside rather than outside. This way, you can find the precise location the cable will enter your property.

To drill the hole, use a thick drill bit. Position the drill’s tip into the desired location for the hole. Balance the bit at an angle of 90 degrees towards the surface. To begin drilling, push the trigger gently. Then, gradually apply greater force to create a gorgeous, consistent hole.

4. Drive the Wire Into the Hole

Continually drive the cable into the hole until you reach the other hand. Don’t stretch the cable any further when inserting it directly into an interior location through an exterior wall.

Alternatively, you could run the Ethernet cable through the wall differently. Don’t immediately withdraw the drill from the hole upon drilling it. Pull the drill bit out of the drill. Then, attach one end of your cable to the drill and detach it.

5. Install a Wall Jack

When installing an Ethernet cable in an insulated home, it is reasonable to feel intimidated by the process. Nevertheless, you could use various procedures with an insulated wall, whether foam, fiberglass, or cellulose, that will enable you to run wires through it. But all in all, ensure you do not create insulating gaps that would allow for air entry.

To begin, you should locate where you want to drill. Typically, irrespective of whether you are drilling from the upside or downside, you should aim for the corner of your wall cavity to avoid problems with the insulation.

After making the hole, here is how you should use insulation to snake wire through the wall.

  • Method 1 – Follow the same route you created while drilling when fishing ethernet cable up or down. Utilize a fiberglass rod with a bullnose tip. If the ethernet cable you want to pass through is short, you could fasten it to the rod’s end. However, if you want to push through a longer cable or cable bundles, you could use a pull-cord and thread it through the bullnose to where you made a hole.
  • Method 2 – Fasten a ball chain with a screw-on connection at the rod’s tip. Determine the length of chain you require, ensuring that the rod is always fed up or down a wall and within a few inches of where you cut a hole. After inserting the rod into the corner, use a magnetic retriever tool to capture the chain and drag it to the hole. When you have the retriever chained to the inside of the wall, you can pull it out.
  • Method 3 – This technique requires a paddle magnet and a wire leader magnet. First, use a strong magnet to attach the wire leader to your fishing cable. Then, push the cable tied to the leader toward the wall with an opening. Push the paddle magnet against the wall and move until it links with the leader magnet, after which you can pull the magnet through the insulation using short, quick movements.
