Issue: Wi-Fi Problems
If the Network Communications LED remains off:
 If the Envoy is installed in an enclosure, that enclosure must be non-metallic to allow wireless
communication. Metal enclosures impede wireless communication.
 Stucco and plaster wall construction may contain metal mesh, which can affect wireless range. If
you cannot see your router or access point in the list on the Envoy, or cannot maintain a
connection, relocate the Envoy to be closer to your router or access point.
 The WPS connection window may have timed out. Retry the connection steps.
 Make sure that the broadband router is operational by checking that other devices at the site can
access the network.
 If you cannot see your router or access point in the list on the Envoy, or cannot maintain a
connection, it may be necessary to add a wireless repeater to extend the network range.
If the Network Communications LED lights solid amber:
 Power down all units in the chain, applying power again in this order: 1) broadband modem, 2)
router or Wi-Fi base station, and 3) Envoy.
 Make sure that the broadband router is connected to the Internet by checking that other devices
at the site can access the Internet. If the other devices are not connected to the Internet, contact
your ISP for assistance.
Issue: Cellular Connection Status “Not Connected”
If the Envoy-S Network Communications LED is solid amber for longer than 12 hours and the Installer Toolkit
displays a Connection Status of Not Connected:
 Unplug the modem USB cable.
 Power cycle the Envoy-S, and wait until Envoy-S completely restarts.
 Re-connect the cellular modem USB cable.
 Allow two minutes between any extraction and insertion of the modem cable in the USB port of
the cellular modem.
Issue: Envoy-S is not Connecting with a New Router
If you replace the broadband router at the installation, you need to update the connection information on the
Envoy-S. To do this:
 Connect to the Envoy-S local interface as described on page 29.
 Select Wi-Fi.
 Select Connect Other Network.
 Enter the new Wireless Network Name (ESSID) and Security code.
Local Networking Considerations
DHCP versus Static IP Addressing
If the site owner prefers not to use DHCP, you can set up the Envoy to use a static IP address. Use the
Installer Toolkit to configure the static IP. Refer to enphase.com/installer-toolkit/ for more information on the
Enphase Installer Toolkit.
 Tap the Network Connectivity menu item. This allows you to see if the Envoy is using DHCP or
Static-IP, and it allows you to change this setting if needed.
 Tap Check Network Connectivity to view the Envoy connections.
