Check connection status and cellular
signal strength
When the IQ System Controller establishes an internet connection,
the IQ Gateway Network Communications LED is solid green. You
can use the Enphase Installer App to check the modem status and
cellular signal strength. The IQ Gateway's AP (Access Point) Wi-Fi
network allows you to connect your mobile device (smartphone or
tablet) to the
IQ Gateway.
1. On the IQ Gateway, the AP Mode LED is solid green when the
AP mode is active. If the AP Mode LED is not lit, press the AP
Mode button.
2. Launch Enphase Installer App and tap connect to IQ Gateway.
3. Tap Network.
4. Under Network Configuration, tap Cellular. The app displays
connection status and an indication of signal strength.
5. Check the connection status and verify that signal strength is
at least two bars for adequate data transmission.
