I’m going to get the Core system, or whatever the equivalent is called now that they renamed it. I have fiber optic internet, and thus, wireless as well. Will I need anything extra to be able to play over Xbox Live, such as a router, etc.? There’s also a phone jack in the room I’m planning on setting it up in, is there a cable that I will be able to plug into that and have internet access as well, thus enabling my console for Live? Thanks for the help!
