Let's start with https://discussions.apple.com/message/23112258#23112258
Right. So, I want to run powerpoints on Keynote from my iPad at my church. And I want to do it wirelessly. I know I need an Apple TV to connect to the projector, but how do I create the network for it to connect to my ipad? I guess I need some kind of router, but I have no internet at church, and no phone line. Do I to connect to a phone socket of I don't internet?
Please help me out if you can, but be aware I have only a slightly over amatuer knowledge of networking.
