Disclaimer: I live in Europe, so my house’s walls are made of bricks and mortar, no plasterboard to easily cut / patch up.
I have a room that is generally cooler than the rest of my home and it’s also far away from my bedroom, so I setup my home lab there. Until now, I managed with WiFi, but I switched operators due to soaring prices and I got screwed since the download / upload speed on this one is kinda shitty. Hence, I want to pass LAN cables from my home lab to my home office, which would mean going through two rooms or, correspondingly, two doors. Since it’s my property, I thought of cutting a couple of centimeters from the door frame and then lead the cables through a skirting board and then through the space cut up from the door frame. What do you think? Any other idea?
My dad would always run cords through the HVAC ductwork. Not sure if that’s up to code, but it worked for our purposes.
If you have an attic or crawl space, you could run the cables through that. Or if you have crown molding, hide the cables behind that.
