Welcome to the community!
We do not have a interface of your modem/router page, I would love to help and give it a try.
Can you post a screen shot of the modem/router page on this thread? Also, what type of NBN connection do you have?
To better understand the situation, PM us your account details (Username/Customer ID together with the address on file).
I managed to solve the issue, just for people who might also get stuck with the setup, following are some tips:
Thanks for keeping us in the loop and for the detailed instructions. If I may suggest though, it would be great if you can inform the community the type of NBN connection you're using so everyone can have an idea as to what technology the instructions can be applied to.
As for the authentication, in order for it to work, you need to have the correct TPG username and the port / AVC ID allocated by NBNCo should match our records.
I've been trying to set up my Netgear Orbi RBK50 with my TPG NBN.
While I understand that you need to set up PPPoE and use VLAN ID 2, I cannot get through to that step.
I have the NBN Arris CM8200 (modem) connected to the TPG-issued TP-Link Archer 1600V (modem/router).
I'm trying to connect my Netgear Orbi directly to the Arris CM8200. I plug in the Netgear Orbi to the modem, and it cannot find an internet connection. I have tried the Netgear app and the web login, orbilogin.com.
I did, however, manage to set up the Netgear Orbi network in addition to my existing network. This isn't ideal, but did offer better signal / speeds. This was done by putting the modem/router in Bridge mode (although the VLAN ID was taken, so I used 1 instead of 2). So I know the Netgear Orbi router and satellite are working… just not how I want.
Currently, I have 3 wi-fi networks now – the modem/router is putting out a 2.4GHz and a 5GHz network, and the Orbi is putting out a network of it's own.
How do you set up the Netgear Orbi, plugging it directly into the Arris CM8200? When I use the app and / or web login, it cannot detect the internet connection?
Any help appreicated, thank you!
