Connie --

In the connections list, are those three WiFi connections all showing an icon with a little "dot" on top? If so, those are "ad hoc network" connections, and not (necessarily) connections to the internet -- usually, they're connections to (again, usually) Windows laptop machines that have enabled the built-in WiFi card in promiscuous mode (occasionally for malicious purposes).

Do you have a WiFi router in your house (or wherever you're at)? Does it show up on the list? (maybe it's set to "hide" its SSID) ... ??
