Welcome to the Community!
Sorry to hear that you've experienced issues in connecting to the internet.
The modems that we provide are already configured with the TPG setting for it to connect to the internet once the service has been activated.
Based on our records, you were able to speak with one of our Helpdesk specialists and assisted you in setting up the modem.
Your modem appears to be connected now and you should be able to access the internet.
Should you require further assistance, you may reach out to us again or check our self help options located here: http://tpg.com.au/support
