Hi - can you please confirm whether you need a "modem" to connect to the NBN Network Connection Device? Or can the ethernet cable go direct from the box to a WIFI router (no traditional 'modem' feature)
Just doing some research and note sure if your use of term "modem" is too generic
e.g. https://iihelp.iinet.net.au/General_NBN_FTTP_router_setup_advice (is for FTTP, however does draw distrinction between modem and router)
I would like to connect direct to a Ubiquiti AMPLIFI HD wireless Mesh Router , or ASUS RT-AC86U.
Welcome to the Community!
For all NBN services (FTTC, HFC, FTTN, FTTB, Fixed Wireless) except for FTTP, you will need an NBN compatible VDSL2 modem and not a router.
For NBN FTTP, you will only need a router since the Network Termination Device already serves as the modem for the connection.
I felt inclined to register an account and leave a comment on this thread, given that incorrect advice has been provided by the community moderator.
The original poster asked if a modem is required in addition to the NCD - it's not. The NCD is the modem. To answer the OP's question, in this scenario, an additional modem isn't required, all he'd need is a router.
I'm aware that i'm resurrecting a thread, but it was the first hit on Google, after searching for 'ASUS RT-AC86U FTTC' and I didn't want others to be mislead.
