Procedure to Run Ethernet Cable via Wall

If you are planning any electrical work, you should plan appropriately where the wire is going. Ensure that the cable is suitable for your atmosphere. The followings are some tips to do it with no trouble:

  • You should measure how much Ethernet cable you required for the top to the bottom floor. Ensure that you have enough wire for the underground. If you take the measurement and add additional ten feet, it allows you to run the cable efficiently.
  • Draw a plan where the wire will run in the ceiling. The professional will suggest installing the wire in the corner where it is protected. Ethernet cable has a clip that holds the wire. It is essential to place the mount every four feet that protect the wire from falling.
  • You should check the ceiling part when running the wire. Never try to drill in your area before planning the cable installation. Avoid installing the network cable close to the circuit breaker and near bulbs. You can use ¾ inch drill bit and pull the drill from the hole after drilling the flooring. Stop when drilling cuts in the lower ceiling of the room.
  • Mark the ceiling where you need to run the Ethernet cable. It is critical to look out for the blueprints of your property before starting the cable installation. It allows you to ensure that you thread it in the correct position.
  • You will be ready to stick a finger inside the channel to guide the fish tape into and past the notch where the cable will run. Continue feeding the fish tape all the way through the wall, into and thru the notches, until you’ll pull it out of the wall at the top. Strong string or a fish tape Costs you $30 on Amazon.
  • Run the coaxial cable along upright 2x4s in your attic at shoulder height. Staple these cable loops to the 2x4s and run the cable through them. Keep coaxial cable a minimum of 16 inches from electrical wiring, to stop interference. It is best to run the cable at about shoulder height, along upright 2x4s in your attic.
  • This allows you to cut a hole in your drywall and connect the cable to a wall jack. This way, you’ll install an ethernet jack in any room in your home.
  • Drill a hole within the header and thread the cable down through the opening inside the wall. Then, cut a hole within the wall near floor level and pull the wire through this hole. Install the wire to an RJ45 wall jack to make a secure , reliable ethernet installation
  • Find a neighborhood between the studs and cut a hole within the wall where your box will go as other have described. Then drill a 3/4″ – 1″ hole in top plate within an equivalent stud cavity. that is the easy part.

Ethernet Cable Length Limitations

Ethernet cable has the specific limitation that tends to concentrate on the maximum length of the cable without compromising the signal quality.

The standard Ethernet cable length is 100 meters. The size of the maximum Ethernet cable might vary based on the equipment configuration and quality of the cable. People who are looking for a cable with 100 meters can try Cat5e cable.

Category 6 and Cat 7 cable is more extended than forty-five meters for a 10 Gb connection. Wires can range from 324 feet to 700 feet, so you can select the Ethernet which fit your requirement. The high-performance cable can deliver reliable performance due to the use of copper wires and foil tape.

If you need to wire your whole home, you can get some tips on how to run ethernet cable through ceiling. It allows you to run Ethernet cable in the entire house.

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
