To enable WiFi using a command line, we are told "the procedure is to edit a file (as root user) in the /etc/wpa_supplicant folder."

Once root edits (creates?) that file, what should the file be named upon saving it?

Hi Shabaz,

I have been wanting to play with the new RPI 3 with I/O, but have not had the time.

Now that I see how it can be easily done, I will have to make some time.

Thanks
