[quote name='Milkyman']actually this has happened to me twice recently, dont know why[/quote]
It has to do with the "Remote Play Auto-Start" or whatever it's called. If you enable it, certain routers will cause the PS3 to wake up at random. 2.01 was supposed to fix some of the problems. After upgrading to 2.01, mine turned on once that day, but hasn't turned itself on since.
