Hi. I'm trying to network my house which contains a Mac, a Dell and an Xbox 360. I have attached a diagram of the setup I would like. Wireless is just for the MacBook and I'd rather have ethernet for the 360 and the two computers. My main question is, we will be having one of the cables coming out of the DG834, going upstairs and into another office. Then I would like this cable to go into some sort of box that will split it into multiple sockets. Now, the problem is: I don't know whether the box marked with a ? should be a network switch or a router. Although, if it was a router, would there be a problem having 2 routers on one network? Also, I want the Mac downstairs to communicate with the Xbox with Connect360. Please help me with this. Thanks. EDIT: Also, for note, the ADSL/Router downstairs is a Netgear DG834 (1st Gen). Any reccomendations for the '?' upstairs are welcomed. Also, will 2 Netgear boxes work together?
