I'm working through different ideas in my head on how to get 2 CAT6 cables from the modem (first floor - west side) to my media system (second floor - north side). Note that this is a Canadian home and the exterior walls are packed with insulation.
Looking through videos online, most guides say to go through the attic, but that would involve at least 2 cuts per wall on all 3 floors of the house - which I want to avoid if possible.
I've considered using the vents and return ducts, but these are not in optimal positions, nor do I know how to get the cable from the duct into the wall. If that involves cutting drywall, why can't I just fish the cable through the wall without drywall?
Should I just run the darn thing outside by punching through the wall? Or is there another way to do this that I've missed?
Just spit-balling my thoughts above and things I've considered, provided some sketches of the layout as well, including locations of the HVAC vents and return ducts, as well as where I want the Ethernet ports to go.
I'm open to all suggestions/ideas/thoughts.
