I received this modem, but the user guide advises only how to connect. Not how to use. Its working. But would like to know what each indicator light means, what to do when they go off/on (trouble shooting purposes), and what the WPS and WiFi buttons are for. Hope someone can help
That's the 5366 LTE (Optus Ultra WiFi modem with 4G back-up)
Note that since some people have received the incorrect SIM for the 4G backup service you should check that the 4G backup service works by temporarily disconnecting the DSL/WAN cable.
