I have received a text requesting that I plug in my nbn device and modem so that my nbn service details can download into the devices.
However, when i attempt to do so the blue lights simply flash and never stabilise.
Can you please check that the nbn service has been connected to my residence and advise of the next steps.

Cheers.
