Welcome to the Community!
We were able to locate your account using your community details and understand that you are under the NBN HFC technology.
Your Netgear d6300 shows that it is a DSL modem, which may not work with the NBN HFC technology as it requires a VDSL modem.
You may check with Netgear support if the said device is compatible with NBN Co and if you can configure it to have a VLAN ID 2.
Let us know if you need further assistance.
