I dunno how your internet works (i.e. cable, phonelines, etc) but when I got wireless I went out and bought a router. I installed it at home by myself, it had a disc that pretty much tells you what to do. Just don't make the mistakes I did: make sure your laptop has wireless capbilities and (unlike myself) make sure they're turned on. I'm not sure how that'll work with anything but cable (which is what I have).

Uhm...hope I didn't hopelessly confuse you more (I'm not so good at explaning myself sometimes). Good luck!
