Help! Factory reset Nighthawk X6 R8000 and now no connection

[ArcheausGalacto]

We lost the user and pass to the router and forgot the security questions. In an attempt to fix this we factory reset the router and now there is no connection. 

I have tried restarting it and letting it sit for over 30 minutes but I never got a connection. Nothing returns when I search 192.168.1.1 or www.routerlogin.net.

Please advise as to how I can set it up.

What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

Try using MS Edge or Firefox browser...with a wired PC connected to the back of the router.

Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.
