Last house I lived in up North in MN, I wound up buying and installing a 16 port low loss splitter for the cable TV. It wasn't very expensive. We had ethernet & RG6 run to each room. If you're in a metro area, anywhere NEAR TV or radio stations, use quad shield RG6 for the cable TV. I had a four port router and two 4 port switches hooked into my network plus wireless. (never cared for wireless as I always seemed to experience slower connection speeds)
