Welcome to the Community @jaiganesh24
For customers who would like to check the status of their service installation/activation, we have created this community article, which contains a video on How to track your TPG service installation
We also send an email notification once the service is activated. If you have received this email and the service is still not working, we recommend to check if the equipment is properly set up by going to this link : NBN Fibre to the Curb (FTTC) Setup Guide
We've also created an article that will guide you on how to setup your router or check if it has the correct settings. Check this link.
Feel free to search Community for help with your issue, or contact us and we'd be glad to assist you.
