Too frequently my Mac connects to WiFi but can’t access the Internet on cafes (my iPhone works properly). It has been tormenting me for over a year and I tried everything I found on the web but still could not resolve it. So I finally want to reset the WiFi settings.
However, if I reset the WiFi settings on my Mac, it erases all the saved WiFi passwords I connected on cafes, which have more than 500. It is not what I want to do to ask each password again whenever I enter the cafes again, so I rather want to back it up and restore whenever I want.
Is this possible?
