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.
If you don’t care for the looks, just put it down where needed, and fix it to whatever is around with cable ties.
I did the same in my daughters shared accommodation. Officially they had wifi in all the student rooms, but my daughters room basically had no reception, so I ran a cable from the other end of the flat where the router was down the staircase into her room for a local AP. When she moved out, it was a quick job with a pair of pliers to get it out again.
