The Enphase Envoy part number ENV-120-02 comes with a wireless adapter (Wi-Fi stick) and an Ethernet cable. Enphase does not recommend using both the cable and the adapter simultaneously. The Wi-Fi stick must be installed in the USB port closest to the cable trough.
If you do not know or need to reset your Wi-Fi password, contact your Internet provider for instructions.
