Cat 6 is on my list to price out with our electrician. I thought the same "but wifi" and "5G" solves all of our problems, until you realize that the ONE spot you can place your router interference from the microwave can really limit the signal strength at the TV. And cheap LED light bulbs...more interference. I'm all in support of wireless for the sake of convenience, but nothing will outperform a hard line in my mind. I'm not sure I'll run Cat 6 to EVERY room/location but certainly the living room, office, and the basement TV/"theater" room.
