I was lucky and in my new house there were two CAT 5 TP cables that ran to two separate outlets on each floor and back into a compartment under the fusebox.
I am not very good with cables but putting a cable box on the wall socket was suprisingly easy.
This is what you need:
- The outlet box from Jula
- A flat screwdriver
- A clipper, i used a small nail clipper actually
- An ethernet tool to remove the plastic around the cable (you can also use your fingers)
Now just push the small wires down on the respective clips. The clips are color coded so you can not do wrong. If you do not have the cables inside your wall, just strech them alongside the wall and use this kind of outlet from Jula
