R6400v2 router cannot update firmware

I have read several posts.  My router web page does not offer a login.  I only get a white blank page.  I sweep the cursor over the page to see if the cursor ever changes and it does not.  The page appears to be completely blank and no way to log in.  From what I have read the recommendation would be to flash the firmware with tftp.  The direction say to start this when the power LED is flashing amber.  My power LED never flashes.  When I turn it on it is dim then ON as Amber and stays solid amber while other LED may come on / off at time, usually white until the power LED goes from Amber to White but never flashes.  I am not sure when I need to start the tftp command.  I have tried a several different places in the power up sequence but the response is always connection failed.  This happens right away if the power LED is white.  This happens after several seconds if the power LED is amber.  Are there any suggestions for how I can flash the firmware or is that not possible given the sequence of the power LED?

    What do you see? Which browser are you using? On what device?

    First work out if you have broken firmware. What does the power LED look like when you turn it on without trying to do anything? If it ends up as solid white, then the problem is something else. Playing around with TFTP could kill it.

     

    Have you checked that the power adapter is OK? Do you have a compatible alternative that you could try? Maybe something from another Netgear device with the same power needs.

      If I use chrome or ms edge I just get a blank white page.  No data, just white screen.  I tried firefox today and the result was still not successful.  If I do it without internet then I get a error that it cannot file routerlogin.net  if I do have internet from a different source (the netgear router has not internet as I am in a hotel and not at home.  I get a different result but it cannot find a page it is looking for.  In all cases there is never a login page.  The router is a Netgear AC1750 Smart WiFi Router model R6400v2 and I have tried this with my personal HP notebook running Windows 10 and my work Dell also running Windows 10.

       

      The power LED starts out dim but soon is bright AMBER and the port that I am connect to (I have tried 1-4 the same results) is bright WHITE.  The port light blinks on occasion.  After a while I will get the port light goes OFF and the next to the last light goes on then I get the 2.4 and 5G lights white; and the power LED goes from AMBER to WHITE but is always solid ON.

       

      The AC power adapter is 12VDC @ 2.5A and is larger than the other adapters that i have.  It appears to be OK since the lights on router seem to ack OK except that I never see the power LED blink which from the documents I have been able to locate is the sign that I can do a tftp to reflash the firmware.

        That looks like typical boot-up sequence. No suggestion of bust firmware.

         

        Have you started with the simplest move, a reset?

        As this is an older router (2017), if that fails you could try this;

        • Press reset for 30 seconds
        • Keep pressing reset while removing power
        • Keep pressing reset for another 30 seconds while apply power

        It isn't advised on newer routers with their different chips, but your "senior" device might respond to this move.

         

        This is puzzling:

         

        if I do have internet from a different source (the netgear router has not internet as I am in a hotel and not at home. 

         

        There's not much that you can do if you aren't sitting next to the router. Netgear disable Remote Management quite some time ago.
