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.
You can get surface mount cable raceways that connect to the wall with adhesive. Works well and also looks great.

Another option is called “sticky backs”, they’re not as nice looking, but they’re commonly used by electricians in cabinets to secure wires:

One thing is if you’re really concerned about the walls, maybe put a strip of masking tape on the wall before the sticky backs or cable raceway. That way you don’t need to worry about the adhesive on them taking the paint off afterwards.
