Not sure where the best place to ask this is . . . I've just got a new dual band router. At present I have the 2.4GHz and 5.0GHz bands having different SSIDs. But I've read that you can give them both the same SSIDs and passwords and then your iPhone/iPad/Mac will connect to whichever it thinks is best. Which sounds good, but is the choice dynamic? If I move to a different room, will it switch bands if the other one is better in that room?
