Welcome to Community!
We have been advised by NBN Co that they have performed a software upgrade to address a potential network issue.
I have since raised the connection issue to our Engineering team as since there's no signal being detected. An update will be provided within the next 24hrs.
I understand that the service is currently not working however, please ensure to leave the modem connected and turned on for remote testing purposes.
Feel free to let us know should you have further queries.
