When i try to connect my iPad 2 to the guest WiFi at my school, it just has the loading circle and wont connect, however it will connect to my home WiFi perfectly fine showing the little check mark. i have tried factory resetting the internet options and it did not work. Update (01/16/2020) PROBLEM SOLVED!!! After a quick factory reset on the iPad it will connect to my schools WiFi
Have you tried opening a browser? Usually with these cases you are required to login some other way besides using just the Wifi password, especially at a school. Check with your front office, they probably have the login information (unless it’s not actually a guest account for students, in which case you’re probably out of luck by normal means)
