Welcome to TPG Community!
We were advised by NBN Co that the connection should start working as they are able to detect a power coming from the NCD (Network Connection Device).
Please make sure that everything is properly connected. You may refer to the article that we've created that will guide you with the set up.
If there's no changes, please send me a PM with your preferred time and best number to be contacted for us to arrange a call from our Provisioning team.
