• Power down all units in the chain, applying power again in this order: 1) modem, 2) router, and 3)
Envoy. Allow a few minutes for the IP address to be reassigned.
• If you replace the broadband router, configure the Envoy Wi-Fi settings for the new wireless network
name (SSID) and password.
Issue: Wi-Fi Problems
If the Network Communications LED remains off:
• If the Envoy is installed in an enclosure, is the enclosure metallic? Metal enclosures may 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 Modem Connection Status “Not Connected”
If the IQ Envoy uses an Enphase Mobile Connect, the IQ Envoy 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 IQ Envoy, and wait until IQ Envoy 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: IQ Envoy 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
IQ Envoy. To do this:
• Connect to the IQ Envoy local interface as described on page 29.
• Select Wi-Fi.
• Select Connect Other Network.
• Enter the new Wireless Network Name (ESSID) and Security code.
