====== OctoPi ======

===== Configure Wi-Fi =====

Run ''raspi-config'' which will create/update ''/etc/wpa_supplicant/wpa_supplicant.conf''.

Then create ''/etc/network/interfaces.d/wlan0''

  auto wlan0
  iface wlan0 inet dhcp
    up iwconfig wlan0 power off  # Disable power saving, so it stays on. Confusing, right?
