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.
