I have a Dell Inspiron 17R/N7110 (Core i5 2410M, Intel HD Graphics 3000, 8GB RAM DDR3 1333MHz, Windows 10). I can't connect to my school's wifi network, which works fine (I can connect to it on my phone). It works fine when I'm home or at other places but for some reason it doesn't work when I'm at school. When i try to connect to it, it says "Connected, no internet". Any help is appreciated.
