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 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 wireless access point 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.
WARNING
: Do not change the Envoy DHCP setting to use a static IP address unless
you also reserve the same IP address on the broadband router. See the section on
DHCP reservations in the router instructions. Failure to reserve the static IP address on
the router may result in duplicate IP addresses and intermittent Internet connection
problems with the Envoy-S.
