Wireless doesn't work on college campus

I can connect to the school's campus wifi, but when I try to get on Opera, it will not let me connect to any website. Apps that use the internet do not work. I get bars on the wifi. Usually, on the first connect from a new device, it will ask me to register my device. I am guessing that since I haven't registered with the new device, I cannot access the internet with any apps. The problem is that I usually get the page that asks me to register my new device when I try to connect to a website. Opera doesn't take me to that site, though. The wifi works on all other devices. Edit: When I connect to the home wifi, it works.
