How do I get rid of launching a webpage while coecting with Idea Netsetter?

I've Idea Netsetter through which I coect to mobile inteet. As soon as inteet is coected, it opens ideacellular.com in web-browser. This is also set to function when clicked on "Inteet" tab from Idea Netsetter.

I want to get rid of this i.e. it should not open any webpage after I coect to inteet. Or at least provide me a work-around for changing a web-address i.e something like replacing ideacellular.com with the address that I want to open.
