As others stated, it sounds like you are connecting to an Airave. One thing that might help you analyze it - when the Airave is connecting the second tone is a higher pitch note than the first one, and when it is disconnecting the second tone is lower.

Kind of like: connect = boo-OOP, disconnect = BOO-oop. If nothing else, you can tell whether your signal is better when you are connected to the neighbors Airave or worse because of distance from it.

The Sprint guy was wrong about you not being to connect to the Airave. Up to 3 Sprint phones can connect at any one time and it doesn't matter whose phones they are.
