1. Right now I have my Macbook setup wirelessly to allow an ethernet cable ran from it to my 360 to play online. The screen has to be opened to keep the internet going. If it goes to sleep, I will lose the signal, and be logged out of live. What settings do I need to allow it to not sleep after being idle for so long? And can I keep it from going to sleep, but still allow the screen saver to come on? Basically I need to know how to set it up to keep receiving the signal without going to sleep.
