We believe that the settings for Netgear D7000v1 and Netgear D7000v2 are almost the same.
Nonetheless, you need to make sure that the following settings are properly configured:
Multiplexing Method : LLC Based
Encapsulation : PPoE
Login: Your TPG Account Username
Password: Your TPG Account Password
You need to make sure that the TPG account details are correct. You can verify it by logging in to TPG My Account : https://www.tpg.com.au/home/myaccount
You may send us a screenshot of the modem's interface so we can double check.
So I did a full factory reset, let the D7000v1 reboot and the Wizard took over, put my UN and PW in and it worked! Online with it now, Speedtest was great.
I went to the Internet settings page and the multiplexing Method is now set to 'VC-Based', VPI8, VCI35, PPPoE, Dynamic IP, Auto DNS, NAT Enabled, Router MAC is Use Default Address, Transfer Mode is ADSL(ATM), DSL Mode is Auto.
