I've been using Ubuntu for a while now and wanted to switch to Mint. I connected my mobile broadband dongle (Vodafone) for the first time like in Ubuntu it all went fine but subsequent connections were denied. I tried connecting with other network dongles and they could connect me to the Internet. My main dongle with the most stable internet connection is Vodafone.

How can I remove or forget the setting and do it as fresh again?

If anyone has better options as well, I am willing to try it.
