Most academic or professional facilities that have Wi-Fi networks require users to login (i.e., provide username and password information, versus just providing the network password). All iOS devices have a neat feature that automatically logs you into such networks after you enter your login info the first time. This feature is usually toggled automatically when such networks are detected, but you can also turn it on manually by going to Settings -> Wi-Fi, and click the blue arrow to the right of the network’s name. Finally, toggle the Auto-Login feature on.
