Wi-Fi keeps turning off on iPhone?

Whenever i get on the Wi-Fi network at my university the Wi-Fi keeps disconnecting on my iPhone 5S, it's a network where you need to login with your e-mail and password.

So. It always connects for like 5-20 seconds and from the moment I close the settings app or go back to the settings overview coming from the Wi-Fi settings it disconnects automatically.

And the weird thing is, when I'm on my MacBook or iPad it simply connects without any problems. What could be the problem?

What is the problem

Did you try reseting the network settings see if that works if itwont work then just visit a apple store
