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?
If I have to, I always drill near the bottom, behind the baseboard (if my translation is not completely off). I hide the hole behind it and when the next wallpaper change is necessary I make a slit to the normal height and install an outlet. As a short term solution you can use the cover as cable duct until you are ready to do it properly. Keep in mind to always make straight cuts so you always know where your cables are going.
