Can wireless and Either be used ? .. Obviously, not both at once, but either or ? I am currently connected via Ethernet to Apple TV setup at home to wireless router.. (I could connect via wireless, but i'm thinking, theres no point as router is right next to it. However, it "would" solve want i'm about to ask) In any case, the only way i can use my Apple TV over at my mates place would my over Airport express, Being WPA2, can you change to either net or Wireless at will ? or will Apple TV loose the password when u change connection?
