I am not one to be insulted or nuffink, but I bothered to give you a full answer to your question, including exactly which bit of kit you should buy, and without saying that you should junk AOL, your preferred ISP*, and instead of a cheery "thanks" you just restate the problem as if I had been p1ssing in the wind.
Not very encouraging for people to help really.
