I have a restaurant in an old building and am needing some network help. I have a dining room with a new apple airport extreme wireless router. Plugged into that router I have my POS file server and a unmanaged switch with 4 receipt printers plugged into it. I am adding a dining area in another area of the old building where my wireless router does not reach. I want to add another airport extreme and unmanaged switch for about the same setup. But do I run one network cable from my main airport to the extended one and then connect the other unmanaged switch to that router? Or do I run two network cables one to connect the two routers and the other to connect the switch to the existing switch? Which is more efficient as I may be playing some media from the internet from a roku device to a tv in the new room?
