Assistance: R7800 TFTP macOS
Our R7800 has become unusable. Trying to upload firmware via TFTP using the following Netgear instructions: https://kb.netgear.com/000064624/How-do-I-upload-firmware-to-my-NETGEAR-router-using-T...
This all began with a power outage. I disconnected everything until the power came back on. The unit was attached to our ISP Modem via a WAN port (not DMZ). When the unit came online, there was no Wi-Fi signals. Although I was able to acess the internet via Ethernet via the unit. I was also able to access the menu. Per the menu, the WI-Fi antennas were active and on the router, the Wi-Fi light was illuminated, but the 2.2 and 5 GHz. lights were dim. Since I was having no luck getting the antennas to activate, I elected to reset the modem. After that, I could no longer acess the menu.
I have tried both Safari and Firefox.
Prompt via Safari:
Safari Cannot Open the Page: Safari cannot open the page :192.168.1.1" because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait a few minutes and then try again.
Prompt via Firefox:
Unable to connect: An error occurred during a connection to 192.168.1.1.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
I am not using a firewall or proxy.

Pretty well the best way around of killing electronic equipment, especially when accompanied by thunder and lightning.
That could be the case, but I am not entirely sure. We have been having a lot of odd power outages with no discernible cause. The unit was connected to surge suppressor, that still seems to be functioning properly.
i was able to replicate that my ISP Modem/Router, to which it was connected, was not authenticating properly. It would, after losing power, only partially authenticate. It would receive proper Private IP data, but not a proper Public IP (Dynamic IP). It was retaining its pre-authentication IP. This would allow access to the Internet, but would act erratic. I was to correct this by requesting a new network logon password.
My thought is that after resetting the modem, it may have attempted to update the firmware in this confused state. That the firmware is corrupted. That is why I was attempting to reload clean firmware via TFTP.
As I mentioned, if I cannot get into the units menu, I cannot configure the unit to do much of anything.
I am making one last attempt, before declaring the unit permanently damaged, via MNRP Flash. I am presently installing BREW and then will attempt installing MNRP Flash.
Do you have any experience with MNRP Flash?
