Welcome to the Community @ImDying
For customers experiencing any issues with their ADSL and NBN service, we recommend the best thing to do first is check if there's an outage on the network.
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. Also, you may refer to our article Slow speed issue.
Feel free to search Community for help with your issue, or contact us and we'd be glad to assist you.
