The wpa_supplicant.conf file

The first line you must provide in the wpa_supplicant.conf file is a country code. These are known as iso/iec alpha2 country codes and you should find the appropriate country code for the country you are in, by going to https://datahub.io/core/country-list. This is important, as the Wi-Fi adapter will be disabled by Raspbian if this is not present, to prevent it from operating outside the country's legal standard, and interfering or being interfered with by other equipment.
