I can see that you were contacted by your Case Manager already. As discussed with you, your NBN order is currently in-held. NBNCo cited that a network augmentation is required to complete the order. As advised, the Planned Remediation Date (PRD) is June 18. This is still subject to change.
As for your modem, let's wait for the completion of the order so we can look into it further. The most likely reason why it failed to work is because the automatic configuration was not able to kick in since your current account is still ADSL. Once the NBN order is completed and the account switches to NBN, the modem can then automatically configure on its own to allow you to go online.
Should there be any changes to the PRD or the status of the order itself, your Case Manager will contact you directly.
