I'm sure it's some kind of interference being in a highly developed suburban area. I'm only g capable with the Minis. There are currently 4 networks showing up - 2 are mine (AP Express and the D-link for my wife's wireless access), the other two are local, but very weak. I've seen as many as 6, though. Before the last couple of iTunes updates, there was never a problem. I wonder if iTunes has changed the way it negotiates the connection.
