Additional Points: iPads are "sticky" when it comes to wifi, meaning they will try to stay attached to an access point as long as possible. So if a student connects to an access point in the west end of the building and goes to a class on the east end, the iPad will try to stay connected to the original access point as long as possible, even though there may be a closer access point with a better signal. Have the student turn off their iPad, wait for 10 seconds, turn it back on and let it connect to the closer access point.
