Welcome to the Community @enelrahcly
For customers experiencing any issues with their NBN service, we recommend the best thing to do first is check if there's an outage on the NBN network.
We have created this article that can guide you on How to Check for NBN Network Outage
If there are no known outages in your area, customers can proceed with the troubleshooting steps indicated on this link : https://www.tpg.com.au/support/nbn-hfc-cable/problems_connect_internet_nbn_hfc
We were able to locate your account using your community details and reviewed the case. It appears that the issue was caused by a faulty/damaged NBN NTD box, which was resolved after the attending NBN technician replaced the equipment.
Feel free to search Community for help with your issue, or contact us and we'd be glad to assist you.
