FATAL FIRMWARE UPGRADE ...... AVOID 1.0.4.28 version
ABSOLUTELY DO NOT USE FIRMWARE VERSION 1.0.4.28.
It is completley BUSTED - and because Netgear only supports their prodduct for 90 days - you are pretty much guaranteed to be SCREWED if it goes south. I happen to have a pretty good idea of how to salvage a device firmware failure - and also got lucky to get it back working ... with only WASTING 2 HOURS of my time.
I just spent 2 hours fighting with my Netgear Nighthawk R9000 and external Motorola MB8600 Ultra Fast DOCSIS 3.1 Cable Modem. I upgraded from 1.0.4.26 to .28. The upgrade went smoothly. But on reboot of the WiFi router, no Internet connection was estabilshed. I went through the usual pain of unplugging LAN ports and plugging them back in, powering off the WiFi router and back on. Powering WiFi Off, Motorola Off, wait 1 minute, then Motorola on, wait 10 mins, then Wifi ON ... 3 times.
I gave up and connected my personal cellular hotspot, downloaded the 1.0.4.26 version, backrevved the WifI Router, then went through 3 more power off/wait/power on cycles before the WiFi router would finally acquire connection to ISP.
ABSOLUTELY NOT SAFE FOR CONSUMPTION.
