I NEED WIRELESS INTERNET?

What you're wanting is called a wireless router. They run $40 - $60. You can get them anywhere: Best Buy, Wal-mart, etc. However, they are not inconspicuous. It will be around 6 inches by 8 inches by 1 or 2 inches. Although, you could get a long enough ethernet cable that you could maybe stash it under a desk or something. I can't believe your parents set a curfew for you when you're 19. Well, maybe I could see having to be home by midnight, but locking you out of your study room and making you go to bed? That's just ridiculous (speaking as the dad of a teenager and a former 19 year old myself).
