Latest R7000 firmware update breaks router . Unable to do a reset

Oh! On the R7800 issue, always check if the issue is the modem or router. My router told me that it had no IP address from the modem. There was no resetting modem and router to correct this. After hours of many troubleshooting tries, I called Comcast( Xfinity) and a great technician connected me to a netgear tech. He asked me to connect the computer to the modem. We connected to Internet. I then reconnected to router and bingo was on the air on Internet. Where is the problem? I’m happy to have a way to fix my problem quickly. I think that there is an interface issue with the R7800 and my modem and/ or Xfinity. Life is too short to deal with this constantly. 

Thanks for for all your help. I saved a few bucks on an another router.

I only found the issue solution because the tftp2.exe routine that i also  tried was showing the file location that it was going to for the file. Under CMD you see very little.

This was explained earlier. (See above.)

There is an easy way to see if the firmware is available to TFTP. No need for an IT person.

At the CMD prompt, type DIR.

You will then see a list of what is in the active directory. If the firmware isn't there, it won't work without a bit of trickery.

It is useful, but not essential, to have the firmware in the working directory. You can include the directory in the tftp command.

If you are in CMD, just type tftp and it will show the commands that you can use and the possible modifiers.

So you can use something like:

tftp -i 192.168.1.1 put "E:\Downloads\Software\Netgear\[firmwarename]"

You may not need the quotes. They are only there to deal with any possible spaces in the path to the file.
