I'm having problems connecting my phone to the wifi in my University. I recently upgrade my Samsung J5 to an Xperia XA2 but I never had this problem with the J5. This is not my first Xperia and i've had a similar problem with the first one, which was the Xperia M2. Is their any way of fixing this as I don't have the option to reset a router and I live on campus and rely of Wi-Fi?
