2. Add the following lines to wpa_supplicat.conf files in the BOOT directory. (if you didn't find the files, create it)
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US
 
network={
        ssid="your_real_wifi_ssid"
        psk="your_real_password"
}

Note: you need to change your_real_wifi_ssid and your_real_password" to the real ssid and password

3. Inset the card to Raspberry Pi and power on it
