Welcome to the community!
I was able to locate your account and ran initial tests. It shows your service has been connected for 5h 56m. Please let me know should you require further assistance.
It's good to know that you're finally connected to your service.
Please note that resetting your modem will bring it back to its default factory settings. After doing a reset, it's advisable to just leave the router powered on and idle for around 30 minutes to give it enough time to retrieve and save the required settings from TPG to connect automatically.
Once this is completed, the Internet light on the front of the router will become solid green.
