C.S.
The problem with a place like starbucks is that it's a PAY place. You need to try somewhere like Panera or McD's where the wireless is FREE. There's should be an icon of a computer on the blue line at the bottom of the screen? You can click on that to see what wireless networks you have available and what you can connect to. Sometimes you have to TELL it to connect, and when you open the browser you have to accept it's useage terms.
Hope that helps?!
