Hi, I have read a lot about how to get the router ax88u working with NBN and all cases the information given was ridiculous.  Things like activating double WAN or setup a VLAN, etc... I am going to tell you how to make this router getting the data (accesing the internet) from the NBN NCD.   Login into the router Quick Internet Setup Internet connection type: PPPoE Tick on Special Requirement from ISP. (This step is the most important one where everyone misses) (You will then have a list of ISP and select TPG) Enter your username and password (not for router but for the TPG account) You are done. Now you can use the router that TPG sent you as an extender if you know how to configure this. Not sure the level of knowledge TPG engineers have, but on the online chat the engineer told me to use the RT-AX88U as a backup modem!!!. a $550 "modem"! vs the archer. First of all, it is not a modem. the RT stands for router. The modem supplied by TPG is a modem/router. but the actual modem is the NBN Network connecting device (NCD). TPG's "modem" is used as the router. I am a network engineer myself. The service provided by TPG is fantastic but at this moment in time everybody should calm down a bit and have more understanding about the work they are doing under these circustances. Cheers     ...
