I guess I'm not understanding. Why can't you surf on the school WIFI? The username/password gets you on the LAN doesn't it? That should have internet access as well as intranet access (school specific stuff that you need the login for). You must have connected at a WIFI hotspot before, e.g. Starbucks, McDonald's, airport, hotel, etc. Those are unsecured WIFI for internet access and usually just connect when you detect them if they are free. Private home, secured (they have a small lock on the SSID) networks have the keys and passphrases. It's usually businesses and schools that have the logins. Am I understanding your question?

OK, well I just read your first post a little more carefully. Your school must not have WIFI and it is a wired ethernet LAN. But then you seem to know the login of the WIFI you are trying to connect to. Do you know this SSID?
