Ok first, try not to use phrases like "gAyOL" here, it sounds childish and some members may take offense to it.
Now on to your question about your network issue. At my school, in my dorm room I connect to the internet using the ethernet plug up. It's faster than wireless and it doesn't phase out (unless someone screws the network up...different story).
When I go to class though, I connect using my Airport card to the wireless network. If you have not set your wireless card up yet, then you will have problems and need to get help for that first. For now though we will assume that yes you have set it up.
Now when I log onto the wireless network, all I do is enable my airport card and it connects automatically (assuming there is a signal). After that, I am on the campus network. I can share music on iTunes, get on Rendevous and thats about it. When I open a web browser the first page that usually comes up is an authentication page. It asks me for my email username and password. After that I have access to the internet from the wireless. It stays connected as long as I haven't disconnected for more than 5 minutes (aka closing the lid for a period of time).
Now do you know yet how your school's wireless setup is? That is the first step to figuring this out. What school do you go to?
