In my media closet directly behind my TV, I have my modem. I also have at least 4 other internet enabled devices, such as DirecTV DVR, BluRay DVD; Roku and laptop. I would like all of these to be connected directly to the internet via hard wired connection. Should I use setup internet Modem to wired router and plug in the devices to the wired router; OR, should I plug a Netgear switch into the modem and connect all the devices to that? I am confused over best way for each device to connect direct to the internet, and which piece of internet hardware I should be using.
