Hi there, I received my new Nighthawk AX12 router this week and had to wait until this weekend to try and connect it since we both work from home and have over 20 devices that need reconfiguring to connect to the new network. I purchased the router on the strength of this review: https://www.reviews.org/au/internet/best-nbn-modems/#Best_NBN_Modem   With a title of "best NBN modem" I expected the product to have modem features, however after trying all afternoon I've discovered that it does not perform the same as my old modem router. i.e. it will only work if I keep my old router connected to the internet and use one of the old routers LAN ports to connect to the WAN port of the Nighthawk. This proves the device works, but does not free up my old router so that I can give it to my mother-in-law. Please refer to the attached sketch, which shows my old router connected and working with also the new router only working when connected to the old router and not direct to the Internet port. I have made sure several times that the configuration settings in the Nighthawk are correct, however it gives an error saying "ethernet not connected", this to me says that it does not expect to work with the telephone cable that I use for my FTTN service from TPG, which works as expected when I connect it all back again (i.e. TPG haven't disabled my account). My current modem router is the TPLink X3000 Can you confirm if TPG support this router for my service or can suggest anything else? ... View more
