When I take my iPad to class and try to connect it to the university's wifi network the login screen pulls up but when I click go it won't sign in. As soon as I click the home button the wifi icon disappears and it's back to the beginning. I thought it was the wifi, and it may be, but my iPhone 4 connects without any problems. Is there anything on the iPad I could try? Could the network support iPhones, just not iPads? Any suggestions would be appreciated, thanks.
