I am in a college dorm setup in which I only have one ethernet port. I need to connect my MBP and my Xbox 360, both wired not wireless, to the internet. Maybe I am missing something, but does a simple splitter or hub kind of thing exist where I plug my ethernet cable into one end, and it gives me two outgoing ethernet ports? Therefore, almost splitting up the single connection of the ethernet port? Hopefully so, and if there is, any recommendations? Going to best buy tomorrow... Thanks again
