Before attempting the troubleshooting steps, TPG recommends that you:
1. Check our Service Status at https://www.tpg.com.au/servicestatus
2. "Power cycle" your ADSL modem. This means turning your modem off and waiting for one minute before turning it back on again. This allows your modem to reestablish connection to our server.
If you are still unable to connect to the Internet, you can proceed with the troubleshooting steps indicated on this link: https://www.tpg.com.au/support/problems_connect_internet.php
In your case, the attending TPG technician has identified that the fault is within the internal wiring of your unit. A private technician needs to attend to resolve the faulty wiring issue.
The service should start working once the internet wires are repaired.
