Just finished installing my airport extreme card, but having trouble picking up any signal. To be honest, other than installing the AE card I'm not sure how to setup the rest so that I can get up and running. I was under the impression that I don't need an AE BaseStation and heard about free wifi? Besides that, the only other place I know where I can setup my AE to get a signal is to pay at Starbucks. I'm fairly new to this so any help or information would be greatly appreciated. Thank you!
