Is There a Magic Sauce to a Sticky Apple Device?

Apple devices tend to look for a new access point somewhere around negative 72, something like that. So if your signal is still negative 72, you'll be good. It's really the magic sauce of whoever made the phone, the OS. We can try to influence things with certain protocols on the wireless side, but it's ultimately up to the device. And that definitely adds some confusion and frustration into day-to-day operations.
