Mixed question. Can you split an Ethernet connection into 2? If yes, is it cheaper to do that, or buy a hub (i think thats the name, more connections then 4, like a router). I have 2 computers upstairs connected to the router, I have my computer and the 360 connected to it. All 4 connections are taken up, I am making my PS3 my main media server, and well after a couple hours streaming HD files through wireless, it gets choppy and has issues. So I need one more connection on my router, or I guess a hub?
