My broad band internet connection is from Verizon Fios. They supply their own 10/100 router with their service. What I want to do is connect a large capacity NAS device to my network so I can stream movies to the 73 inch big screen in my living room . My question is can I plug a gigabit switch into one of the ports on a 10/100 router then plug my mac and the NAS device into the gigabit switch, without degrading the performance of the gigabit switch. once I solve this the rest of my set up will be a walk in the park
