Thanks for all of that information Kerry! It is very helpful!

It seems around here (based on the ads and commercials I have seen) many of the wireless broadband configurations require some sort of a device in which you snap into the laptop. It is like a small box or card and I'm assuming it is inserted into one of the USB ports. I'm not sure, but maybe it is some sort of antennae? Or a thing that picks up/receives the signals from the satellite? I'm not sure. And I really don't know what is involved - perhaps ordering it from the ISP company and then installing the necessary software?
This is all new to me. I have broadband in Speedway, but it is not "wireless". The computer is connected by the cable cord and then the signal comes through. That is fine for a desktop system, but not for a laptop. I'd like to be able to move about and take my laptop with me and not be tied down to one spot by a cord.

And it is strictly a dial-up connection over here at Dad's house. It is very VERY slow and cumbersome.
