Welcome to the Community @Yanpan920
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. This will allow you to access more detailed information regarding the cause of the outage.
If there are no known outages in your area, we recommend having a read of our online guide on troubleshooting internet issues for TPG NBN service. Here's the link: https://www.tpg.com.au/support/nbn/troubleshooting
Feel free to also search Community for help with your issue, or contact us and we'd be glad to assist you.
