I don't know if this possible so I thought I would ask. I have a detached garage where I want to use my ATV. In order to get wifi I have to hook up the modem and router in the garage. My Mac will be in the house and will not get the wifi signal. Will I be able to use the ATV without it connecting to the Mac in the house? I want to stream a game from my 4S on ESPN3 to the TV.
