To connect to my internet, I searched for a wireless network in range, and connected to it, and it did. But then, when I try to open Internet Explorer, it either says "page cannot be displayed" or a pop-up window comes up that gives me the choice of either "connect" or "work offline". When I try to "connect," another window comes up that says "dialing..." but then can't get a signal. But I figured this is irrelevant since I am using a wireless network. What could be the problem?
