HP Pavilion dv4170-Need Help With Internet Connections

I am using a Kyocera PC Card from Alltel to connect to the Internet at
home. My laptop is also equipped with WiFi which I occasionally use
when I am at a hot spot. There are also times when I may want to use
a dial-up connection with the modem.

My question is, how do I make these three methods of connecting to the
Internet co-exist so that I can easily switch between them?

I need detailed instructions on how to do this, or directions to a
group or website that may be able to help me with the proper settings.

I do not use a router to connect to other computers at home and don't
need to be concerned with that. But I may want to use an ethernet
cable at a location that has free Internet service, such as a motel.

Thanks to anyone who can help me with this.
