Does anyone know anything about the Belkin Wireless Card?

ok, so here's the thing: i bought a wireless card about a week ago. i didn't to start using it until i got home yesterday because that's what i bought the card for. now mind you, i bought the card not expecting to have to buy anything else (like a router or anything like that) because i don't want to spend that much money, cuz my laptop is nearing it's final days anyway. but i guess my question is: how do i get internet from other people and not getting kicked off? why am i getting kicked off? and it says sometimes that it is linking me with the available network, but it never does? and what is linksys, linksis, linkseys.... they all come sometimes with like two bars, which is pretty good i guess, and my friend said that it is something like a city hotspot or something like that, but it would never connect me. right now as i am writing this, i'm using my wireless card and it's working fine... i wish it can work like that all of the time, but i know that it's not going to work like that
