> I don't know how 2025 houses are built but I would be surprised if they didn't have an ethernet jack in every room to a wiring closet of some sort. Not sure about coax.
Speaking from a US standpoint, it still not common in new construction for ethernet to be deployed in a house. I'm not sure why. It seems like a no-brainer.
Coax is still usually reserved to a couple jacks -- usually in the living room and master bedrooms.
