Through the rooftop is an excellent way of running Ethernet cables from one floor to the other. You may need some drywall restoration to get to the support beams seen between floors. But how do you run Ethernet cables through the floors without causing unnecessary damage?

While wifi has been a convenient way to avoid the hassle of wiring to every gadget for internet access, it cannot always be as productive as ethernet connections. Ethernet cable guarantees optimum connection speed while also providing a stable linkage that wifi cannot.

Suppose you are a highly qualified developer or gamer or want to set up a home office for teleworking. In that case, you are presumably considering setting up an ethernet network because it is the best alternative for a secure internet connection.

In this post, we will be looking at how to run Ethernet cables through floors without causing any damage!

Floor-To-Floor Cabling/Cabling Between Floors

How To Run Ethernet Cables Through Floors

You’ll have more work if your computer systems are on various floors. You require extra wire since your cable length dimension must consider the room’s height concerning the horizontal distance needed to reach the pc.

Below are some ideas on how to go about a multiscale network connection:

Basement configuration

If you have one pc in the cellar and another on the 2nd floor, you’ll need enough wire to reach the condensers.

It may be easier to locate the concentrator on the first floor rather than next to a single computer because you may have trouble finding wire long enough to stretch from the cellar to the second floor.

Arrayed room layout

If the rooms are arrayed one on top of the other, you can run the cable through the inside of the dividers, near the edge. Use open spots around available cooling systems and pipelines and stack closets.

Place the concentrator on the intermediate tier if the stacked rooms have three levels. Place the concentrator on either floor if you’re progressing between them.

Kitty-corner room groupings

If the rooms are on opposite sides of the house, in regards to being on various floors, you must use both walls (or closets) and roofs. Use any accessible entry points around pipes for lateral runs.

If there are no accessible vents, use the inside of the wall. Locate a chase in front or behind the room for the longitudinal runs.

  • Make use of gravitational forces to your obvious benefit. Work from the top down after drilling your holes and locating a space in the wall beside a pipe. Lower a weight on the side of a substantial piece of twine to the lower floor. The cable should then be taped to the twine and hauled up.
  • If possible, use ducts. You can also use HVAC ducts, but be fully conscious that many cities and counties have stringent rules for this option. Some building regulations prohibit HVAC ducts from running cables, while others develop guidelines. Using HVAC ducts is that they’re in each room and are typically quite broad.

The major drawback is that they rarely venture linearly, so connecting a pc to the concentrator may require running cable through many suites. Making a hole into the duct system is never a good idea.

You must use established entry and exit points, generally through the grate over the duct’s junction with the wall.

Running Ethernet Cables Among Floors

It is pretty simple and confusion-free to run Ethernet cables on a flat floor. Having to run ethernet cables among floors, on the other hand, can be difficult due to the need to obtain wires from one floor to another.

We’ll show you how to drive ethernet cables among floors without calling an electrician.

Principal Duties

There are several methods for having to run ethernet cables between floors. However, most folks prefer running the cables through the roof rather than the drywalls because they constitute cushioning.

Nonetheless, before running the wire, you must first complete some essential but vital requirements.

Observing local construction standards

Before beginning any other task, you must verify the building regulations to see if you have the approval to build Ethernet cables in your region.

Although Ethernet cables with low voltage are permitted in most areas, it is always good to double-check the local codes.

However, if you are renting a house, you should ask the landlord if you are permitted to run cables in his home because driving wires demands digging through the ceilings and walls.

Before you pass the ethernet cables, you must develop a thorough plan for how you intend to configure them because an excellently premeditated plan will keep you from running out of wires or digging in the wrong place.

An essential issue is to choose the best route for running the wire. As a result, you should select a location away from any established power wiring, pipes, or studs. To mitigate concealed weirs or lines, use stud sensors to determine whether or not there is a hurdle within the wall.

After deciding on the spot and path for the cables, you should check the number of cables needed. It is always good to purchase 10 feet more cables than the intended amount if they fall short suddenly.

To make the experience go more smoothly, use an indicator or chalk to mark the locations and paths where you want to run the weir.

It will make the work easier and reduce the chances of the project going wrong.

Obtaining the required tools

Another crucial thing is to catalog the instruments required while rolling weirs and purchase or rent them as soon as possible. Or else, it will be pretty uncomfortable if your work becomes stalled because you cannot locate a specific tool.

The following tools are required for running Ethernet cables:

  • Measurement tape
  • Stud Locator
  • Drilling equipment
  • 34-inch drill bit and 12-inch-16-inch drill bit
  • Tape electric
  • Keyhole saw for drywall
  • Use fishing tape or a wire coat hanger
  • Ethernet cables run straight through

Finally, you can begin running the wires.

Interconnecting Floors With Ethernet Cables

Assume you want to run a wire from the basement to upstairs. It would be best to run the wires into the wall cavity, allowing the wire to cross through the ceiling opening between the two floors. As a result, you’ll have to bore into the floor and the walls.

Step 1: First, choose a location for the outlets on both floors’ walls. Remember to consider all of the factors mentioned earlier when choosing a location.

Step 2: Now, twist off the electricity to avert any mishaps. Next, using a metal coat hanger, excavate a tiny opening on the location of the outlet wall downstairs and ensure the hole is clear. If the gap is safe, broaden it by having to cut it to the shape of an outlet frame.

Step 3: Do the same with the upstairs outlet wall. Check that this outlet is not too far from the ground. Then, within the inner chamber, excavate into the floor to allow the cable to cross through from one floor to the other.

Chisel into the floor with a 34-inch drill bit while clutching the drill at 90 degrees to the ground and underside. Cut through to the ceiling below later with a 12 to 16-inch augmentation to the drill bit.

Step 4: Once the drilling is completed, use electrical tape to secure the fish clip or coat chute cable. Now you can slide down the cable tethered with the fish tape through one of the top floor outlets and, after passing through the ceiling aperture, pull it through the bottom floor outlet.

Step 5: You’re finished! You can now start by removing the fish tape and filling up any holes cut needlessly.

Frequently Asked Questions

Is ethernet superior to wifi?

Ethernet is unquestionably superior to wifi because it provides much faster speeds and guarantees robust connectivity. On either side, you can use wifi to connect to the Internet from anywhere in your house without connecting any cables.

Is it able to transfer the SNSS from one computer to another?

Using fusion ethernet cables, you can consider sharing the Internet from one computer to another.

Is it possible to launch an Ethernet cable among floors without drilling?

You might be able to use a Powerline adapter as the nearest option. Purchase a high-quality adapter, as it may cause issues with satellite or cable TV packages. However, if you need to run an ethernet port through external walls, you may need to excavate.


Fill any small stray gaps here between gaps with corresponding wood putty and bigger ones with refinishing dust and epoxy glue. You can pass ethernet cables without splurging if you plan ahead of time and have basic skills.

Nevertheless, if the task appears too complex for a different building layout, don’t be afraid to seek technical counseling.
