tablet) to the
IQ Gateway.

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 Conguration, 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.
