I’m planning out my next homelab when I move soon. I have the floor plans and it looks like the best place for my computer is not centrally located, so the Wi-Fi won’t be ideal. I’d like to run the cables a short distance so the router would be in a better spot.
I’m just renting and will likely only be here for a year so I don’t want to do any drilling. I just want to secure the cables somehow to the crease where the wall and ceiling meet.
The total length will only be about 20 feet to the router.
I’m not sure of the floor plan or roof type. But what I do is run a cable up the corner and drill a tiny hole right in the corner through the ceiling. Then I use a PoE powered access point and leave it in the ceiling space centrally located. One tiny hole you can patch with just about anything when you move house. If you have a rj45 crimper then the hole can be the diameter of the cable.
I’ve also done something similar where I run Ethernet under the floor. I lift up the carpet slightly right in the corner and drill a hole through the floor and run the Ethernet under the house. You also then take it up into a closet etc.
If you’re more adventurous and confident with electrical work you can also TURN OFF MAINS, then open up a wall power socket, disconnect the wires, tie a pull wire and your Ethernet cable very securely, and go into the roof and pull the two through into the roof space. You then tie the end of the elec cable to your pull wire and pull it back down to the socket. You can then get a wall plate that is a power socket and Ethernet female combo and voila….
