Use a wireless network connection with Windows Autopilot White Glove

During the Windows 10 blue OOBE (Out of Box Experience) screen you can press Shift+F10 to open a command prompt window (as long as the device is not running Windows 10 S Mode) and from there you can connect to a Wi-Fi network by running the command:

start ms-availablenetworks:

If by chance your WiFi network needs you to complete a Captive Portal, you can launch a web browser with the following command:
