I don't know wireless connections at all, but as the dial-up network connection, (DUN), is attempting to connect, have a look at your Internet Explorer > Tools > Internet Options.
When there, click the "Connections" tab, and see if the setting that says "Never dial a connection" has been de-selected in favor of one of the other two. If it has, re-select it, and Apply/OK out.
See if that prevents the DUN from appearing.

I think this is a valid OS question. I turned on file sharing because I connected to a wireless router and wanted to share with my laptop. Now a dialog box pops up saying Error connecting to Verizon
connecting through wan miniport and also the dialup connecton box is undrneath that asking if I want to connect. I am already connected to the web through the router and the DSL modem. When I cancel and close the dialog boxes, I am connected through the DSL modem. I went back and turned file sharing off. The do you want to connect box still pops up. What's going on?? How do I make it stop?
