Do you have a small white NBN connection box and archer wifi router?
From my reading, the first light is Power comes on straight away.
Second light is connection; if off or red, there is a problem sending power to an interface box outside your house. Seems to me to be extra work to be done outside.
Third light is DSL; won't come on till 2nd light is on and work is completed in the network.
Fourth light is LAN; indicates connection to your wifi router.
Did the technician leave a number to call to get him back?
