AC1750, Model R6400v2 I just recently updated to the recent firmware and now the nighthawk app cannot find my router nor the IP address work to login. Please help.

Re: AC1750, Model R6400v2

What modem/gateway is the router connected to? 

Is it working? 

what firmware version did you install?

Re: AC1750, Model R6400v2

My modem is through cable provider Spectrum Model EN2251 is on the modem. The latest firmware 1.0.4.122 we did it yesterday. The internet is working I just cannot login to the IP address 192.168.1.1 as an admin to monitor my devices. The nighthawk app states it cannot find my router. So I reboot, reset everything and nothing is working. I just wish I never updated that darn firmware.

Have you checked to see if its at that gateway address? 

Pull up a command prompt in windows and type ipconfig

That'll tell you what the gateway address is.

Re: AC1750, Model R6400v2

so you're caught in a catch-22. 

The next thing I'd recommend would be a factory reset and reinstall. But if it does the same behavior, you wouldn't be able to access it to reinstall it. You'd have to try to recover it using the tftp method of forcing firmware to it.

Re: AC1750, Model R6400v2


are you on windows? if so, follow this guide
https://kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTP
just make sure you enable tftp
https://www.thewindowsclub.com/enable-tftp-windows-10

and here's a video walk through using a tftp client. Use the built in one for windows 10 though. the video is more of an example of how its done.

and if that doesn't work, you can try using nmrpflash

Re: AC1750, Model R6400v2

so again, catch-22. Factory reset and risk it not working. Or order a usb--->ethernet adapter and wait to get it then try the reset. If it doen't work and you need the tftp method, then you have it. If you don't you can return it (or hold it in case you need it).
