I'm trying to figure out how to best wire my rooms for Ethernet. How many switches between the modem/router would be considered too many? I wanted to put a main switch connected to the router. Then wire cabling to smaller switches, ideally in each room. The important stuff would be 2 switches from the router. Some areas would come in a lot cheaper if they were wired behind the 2nd switch, but anything connected would now be 3 switches from the router. Would this cause a lot of latency?
