My R8500 seems to have crashed today, and is now stuck in a reboot loop. I was working (connected to the router via wifi), and the network dropped. I got up to see what the issue was and could see th...

    FWIW, when the support team contacted me (OP), they said it was a hardware issue, and shipped me a new unit (just arrived today).

You can try this. Power off router. Leave it for 5 mins. or so. Then holding the reset button down, power up.

Wait until power light flashes then let go of the reset button. Now does it finish rebooting? Can you ping the

router? Then what is TTL time value?

      Hi,

       

      I`m having the same problem with this model. I Tried the same things too. Is there any solution?

       
      Weird thing this happen almost at same time as with the OP... Have NetGear ran some kind of faulty update or something like that?

        i also have the dreaded reboot loop. I'm using a CP2102 USB TTL board V3.0 to use putty and tftpd64 (windows10). Tried everything I could find online. I feel equipped with the right tools...but so far no go.

    Hey,

     

    Thanks for the tip, but holding the reset button while booting doesn't seem to do anything.

     

    If I set my computer up with a static ip, I can ping the router part way through the boot process. TTL is 100. Here's a sample of the ping output:

    From 192.168.1.75 icmp_seq=744 Destination Host Unreachable
From 192.168.1.75 icmp_seq=745 Destination Host Unreachable
64 bytes from 192.168.1.1: icmp_seq=746 ttl=100 time=3007 ms
64 bytes from 192.168.1.1: icmp_seq=747 ttl=100 time=1999 ms
64 bytes from 192.168.1.1: icmp_seq=749 ttl=100 time=1.69 ms
64 bytes from 192.168.1.1: icmp_seq=750 ttl=100 time=1.65 ms
64 bytes from 192.168.1.1: icmp_seq=751 ttl=100 time=1.67 ms
64 bytes from 192.168.1.1: icmp_seq=752 ttl=100 time=1.70 ms
From 192.168.1.75 icmp_seq=785 Destination Host Unreachable
From 192.168.1.75 icmp_seq=786 Destination Host Unreachable

    Best,

      TTL=100ms means it is waiting for firmware. You have to use TFTP method to reload firmware. You may have to try few time

      to be successful. Don't forget to enable tftp service on your Windows PC
