"Dial-Up connection" window keep appearing on page

I have a Dell xps laptop with Win7 home premium. I have a wireless network connection through my netgear, as it shows when open the "network & sharing center." As the screenshot shows, there is an annoying "dial up connection" window that randomly appears while I'm using the pc. I can't access the inter net while this is there so I have to close it. Sometimes there are 6 or 7 windows on top of each other. How do I stop this?
