Hi there,   I hope you can help me with this please. I have a NBN 100 (FTTH) connection and I'm struggling with wireless coverage throughout my house, especially in the far rooms. Which is expected given that I'm using the original modem from 2017 which is a NetCommWireless N300 Gigabit Router- NF12.   So I've bought a new router, a NETGEAR AC1750 Smart Wifi Router (R6400v2). The rep at The Good Guys said I just need to plug in to the NBN box as I have FTTP and use the Nighthawk App from Netgear to configure through my phone. It doesn’t' t work... Scanned the QR code on the router and the phone connects to the router but says there's no internet; I've tried doing it manually clicking on the PPPoE and inserted my TPG user name and password, and nothing again...     It only works when I connect it by cable to the original modem from TPG, but then I'll have 2 wireless networks at home which is not what I want.    I can't contact TPG for any support as they're not answering the phone. I suspect this should be something simple that a quick phone call should fix.   Does anyone know how to set it up? I'm at the point of returning the router to the store :-(   Thanks in advance for your help. ... View more
