Hi @Yalcinadal,
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
In your case, your location was affected by an NBN outage last 12 March, which was caused by a local power outage and resolved on the same day. There's no reported outage within the NBN Co network last Monday and the service shows that it's been stable.
Feel free to search Community for help with your issue, or contact us and we'd be glad to assist you.
