How to Run Ethernet Cables Between Floors

You’ll learn the step-by-step process of seamlessly running Ethernet cables between floors in just a moment. This guide covers planning, selecting the right equipment, wiring process, and safety tips to ensure a successful do-it-yourself (DIY) project. Here is a 6-step guide below.

  • Planning Your Route

  • Drill Holes
  • Run the Cable
  • Install the Wall Plates and Keystone Jacks
  • Test Your Connection

Planning Your Route

Identify the points where you’ll install the Ethernet ports and plan the path your cable will take from one floor to another. Use a stud finder to avoid drilling through load-bearing structures. Also, remember to consider the length of the Ethernet cable; it shouldn’t exceed 100 meters to maintain optimal data transfer rates.

Gather Your Tools

The tools will include an Ethernet cable, drill, fish tape, drywall saw, grommets, wall plates, keystone jacks, and a crimping tool. Make sure to have protective glasses and gloves for safety.

Drill Holes

Once the route is planned, it’s time to drill holes at your starting and ending points and potentially in-between floors, depending on your path. Ensure the holes are large enough for the Ethernet cable but not overly large.

Run the Cable

Using fish tape, thread the Ethernet cable through the drilled holes. Be gentle to avoid damaging the cable.

Install the Wall Plates and Keystone Jacks

Cut the Ethernet cable to length, leaving some slack. Strip the cable, arrange the wires according to the T568B standard, and punch them into the keystone jack. Insert the jack into the wall plate and attach it to the wall.

Test Your Connection

Once you’ve installed the cable, use an Ethernet cable tester to confirm the connection is successful.

Remember always to respect your building’s structure and electrical codes when running Ethernet cables. If you feel uncomfortable at any stage, consider hiring a professional.
