How to install firmware
I did a firmware update which killed my access to the router. How do you install an older version of firmware when I cannot get to the router? Is it possible? Others say install an older version after ruining access to the internet but how do you do that? Thanks

I did the reset and the power light has settled down on solid white.
This is a sign that your device is working as expected. A flashing light would be a sign of broken firmware.
So you can forget about playing around with TFTP. You should be able to install new firmware without any of that hassle.
(Might not matter but the three band lights are solid white also.)
Not sure what "band lights" are, but the manual tells me that there are lights for wifi channels among other things. If they are on, that is another sign that the device is not bust. You can read about what the lights mean in the manual somewhere at the end of this link:
>>> R8500 | Product | Support | NETGEAR <<<
see page 174.
The important one is the Intern the light. What does that look like?
Your main issue seems to be that you cannot access the router's control interface. There can be various reasons for this. One is that your playing around has confused the equipment on your network and it does not know what addresses to use. You can start from scratch and see if that restores sanity.
Be sure to restart your network in this sequence:
- Turn off and unplug the modem.
- Turn off the modem router and computers.
- Plug in the modem and turn it on. Wait 2 minutes.
- Turn on the modem router and wait 2 minutes.
- Turn on the computers.

If you want more help you'll have to tell us the model number of your device. Look at the label on the thing for that.
Wow. Thanks for the reply. I really didn't know if anyone would get back to me, but I certainly appreciate it.
I have the Nighthawk X8 which is a fairly high end router bought about June 2016, just out of warranty now. At the same time I installed the CM600 modem.
A few days ago I received a notice about an update to the firmware for the router and it looked simple enough to do. But guess not. The modem still works but no longer the router.
Now I am trying to get any firmware to install. What I have done so far is downloaded all the firmware you have on your web site as well as the tftp2.exe file. I have connected a LAN cable from my computer directly to the yellow port on the router, bypassing the modem. (Should I keep the modem in the loop?)
Then, (I am using Windows 10), I went in to try to assign a static IP to the computer (192.168.1.2) and the router is 192.168.1.1.
ipconfig gives me this:
ping 192.168.1.2 gives me this:
and ping 192.168.1.1 gives me this:
So I am stuck not being able to get to the router. Oh, and here is another window that might help see what I am doing wrong.Have I screwed this up?
The router might have gone bad at the same time I tried to update the firmware but that would be weird.
Thanks so much.Looking forward to some suggestions and critiques.

The jpeg's wouild not up load. So basically, the computer would ping 192.168.1.2 (or itself) but would not ping 192.168.1.1 (the router).
In the Internet Protocol Version 4 Properties window I have the following set:
IP address: 192.168.1.2
Subnet mask: 255.255.255.0
Default Gateway: 192.168.1.1
Preferred DNS server: Blank
Alternate DNS server: Blank
So what should I change to ping the router?
Thanks
