I live on the court square in our local town surrounded by many businesses that offer free internet access?

i have spoken with a couple of them and they said it would be fine for me to connect online through their access point and even gave me all the info i need to set it up the problem is that i dont have a clue on where i should even begin -please help!!

turn ur wi-fi connection on —if a laptop –if a desk top u need a wifi card
