I need to spend a bit of time optimizing my network, maybe moving my Airport Extreme to another part of the house. It's currently in a computer room on the 2nd floor and the living room is on the 1st floor on the other side of the house, the Apple TV has been struggling lately.
2009 iMac 21.5", iPhone 5S, too many iPads
