Default [Q] MJ7 WiFi issues?

One major issue I found is that whenever I'm at school the phone connects to the WiFi, but the school wifi makes you log on in after you are connected so it opens up a link on the internet browser, well the issue is that this page doesn't open up! my friend has a gs4 with me7 and his wifi works just fine so its not the wifi , has anyone encountered this issue or found a fix or anything ? thanks in advance
