Are you under the NBN Data only plan or NBN Bundled with VoIP plan?
If via NBN Data only, the router will work by connecting it to the NBN NTD box and configure it with PPPoE.
If via NBN bundled with VoIP plan, then connect it to the NBN NTD box, then configure it with VLAN ID = 2 and PPPoE.
You may send me a PM with your TPG username or customer ID number to confirm the correct configuration.

Hi @thefreddos01 . Are you on FTTP or HFC connection?
Can you reconnect the TPG router and verify the config, VLAN disabled and username format.
Run a speed test to check for Superfast. Use your ethernet computer.
Reconnect Asus to NTD and do factory reset and redo config.
When connected, does the WAN indicator come on?
@thefreddos01 . You say you set vlan 2. This is at odds with what moderator said. You should check in MyAccount exactly what your plan speed is and do a speed test to confirm that.
TPG may have used the word Superfast to refer to two different plans. The Superfast and Ultrafast plans were for FTTP and HFC connections and don't use vlan setting.
