I'm in college, and the university has a Wi-Fi network that has WPA2 Enterprise security. I successfully connected to the network months ago, in the fall, and haven't had any trouble with it since. As of this morning, neither my iPad or iPhone will recognize the network anymore. When I attempt to connect to it, it will exhibit all the signs of being connected but safari won't work and neither will apps that require internet connection. A few seconds to a few minutes later, it will just disconnect.
When I first connected to this network, a window popped up telling me my device is registered and to wait a few minutes for my device to recognize the new network. It did, and I never saw that window again. It is popping up again today every time I try to connect to the network, but it has been many hours since it first did this so obviously something isn't right. Any ideas as to what could be going on here?
