I'm in a restaurant trying to study. The only problem is I can't get on-line. The spot I'm at doesn't provide a WiFi connection. However, the spot accross the street (about 150 feet away) is a hot spot for AT&T customers. When in the restaurant I can't pick up the frequency from this hot spot. But that is just trying to connect with the provided WiFi network card in my laptop. Is there a USB or SmartCard that could increase the chances of picking up these frequencies in different locations? When I'm just a little further away.
