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.
You didn't specify whether you're using Opera Mini or Opera Mobile, Opera Mini uses compression proxy server to optimize the page for your device; and this almost invariably breaks in-browser wifi authentication page since the browser will try to connect to its proxy which it can't do because the gateway blocks access to the proxy until you authenticate. Opera Mobile by default do not use the compression proxy, but if you turn on the Turbo feature then it will use the proxy. 

You still can use Opera Mini or Opera Mobile with Turbo if you authenticate using the regular Browser then switch to Opera.  If you're using Opera Mobile, then switch off Turbo temporarily for the authentication page.
