Raspbian Stretch WiFi Setup

Create a file called wpa_supplicant.conf in /boot. Put this into the file, changing things as needed:



ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
network={
    ssid="yournetworkname"
    psk="yourkey"
    key_mgmt=WPA-PSK
}


Save it. If you need SSH, just copy any file (doesn't matter what it is) and rename it to ssh (nothing else, just ssh)
