I have an AT&T Router/modem bringing the internet in. I have a Netgear N6300 hard wired to it to feed 4 IP cameras. I have a Netgear N600 hard wired to the N6300. I the have the N600 connected to a Netgear Prosafe 5-gigabit switch which feeds my smart-Tv and Blueray disc. My question is: Is this the most efficient way to run my home network?
