Hi @johndagg . If you have bundled NBN/VOIP plan, the VOIP phone only works if the the TPG router is connected to the wall socket. Requires VLAN ID = 2 setting. Asus would only be access point.
If you don't want the phone, or you are on BYO router data-only plan, the Asus should work on FTTB.
Data-only plan does not used VLAN ID.
Select Advanced Settings, WAN, Internet Connection: WAN Type is DSL, VDSL WAN (PTM).
Select PPPoE for WAN Connection Type.
Enable 802.1Q - enter 2 in VLAN ID and 0 in 802.1P
Enter your username and password and select Apply.
Cable goes from wall socket to DSL port.
