Hi @patrickwong94 ,
For customers experiencing any issues with their service, we recommend the best thing to do first is check if there's an outage.
If there are no known outages in your area, you can proceed with the troubleshooting steps indicated on this link: Troubleshooting No Internet Connection
If you are still having issues, please send us a private message with your TPG customer ID, username and complete address so we can pull up the account and further help with your concern.
To send a PM, please refer to this link: How do I private message (PM) in the community
