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?
You could try power line ethernet adaptors instead of cutting up your house with cable.
Also, there’s no right way to do it exactly it depends on your local building codes. For me, if I run cables though any walls it null and voids my insurance policy as it breaks building codes to have anyone other than an electrician do it. YMMV depending on where you live.
