I have a raspberry pi 2 running raspbian, and bought a wifi dongle to use with it. I can't seem to get it connect to the internet. I have tried following the guide given by the seller, but it was written for Headed units, and I want to go headless. I also tried using sudo raspi-config to set up the internet.
