I saw your last video and I have a much easier, way cheaper method that any landlord can't argue with. It's also triphazzard-free and no wife would complain. It's also quite to install
So all you need is to buy long enough network cable that is FLAT, second you'll need to buy 3m tape. I bought the 2mm phonefixing tape. You guessed the rest. Just stick it on the wall next to the floor/ceiling, go around doors and all the way where you want it. The termination of the cable is not as nice as in the video though, if you've got any tips for that, please tell!
Personally i chose a cat6 cable because I have gigabit internet, not too sure if it was needed.

Hope people who doesn't want to drill or want a cheaper solution find this useful.
Edit: CAT6 not Cat6e
