I just wanna make sure I understand how to use this thing before I buy it. First off, my computer is downstairs and my PS3 is upstairs. I want to use a network adapter, specifically this one: http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER to get internet on the PS3. So, if I'm following it right, all I need to do is to connect one box to the computer, and one to the PS3 and it'll get the signal for the internet, right?
