http://unix.stackexchange.com – Hello Linux Gurus!! 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 connection was denied. I tried connecting with other networks dongle and they could connect me to the internet.my main dongle with 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. thanks (HowTos)
