Okay, The more I read about switches, the more confused I get. I am looking for any help. Here is what I have. Two main machines, xbox 360, and direct tv dvr. Those are ran off of a gigabit router. I also have three laptops ran off of wireless n from the same router. I am at the point where I want to hook up a media extender to a different tv, and I am out of ports. What I was wanting to know is there a way that I can incorporate a switch into the network, while retaining internet service to all the pc's... Or do I need to buy another gigabit router. I could do that also and use it as an extender for wireless also. (I think).
