Nighthawk R8500 Amber Flashing Power Light after Firmware Update
I updated the R8500's firmware utilizing the Router’s internet interface from version 1.0.2.136 to 1.0.2.144. After the update, the Router has a blinking amber light.
Steps attempted to resolve amber light (per Netgear KB)
- Restarted router
- Attempted to reset - no effect at all after pressing reset button for >30 seconds.
Next, I attempted to upload the software to the router using TFTP as outlined here: https://kb.netgear.com/000059633/How-to-upload-firmware-to-a-NETGEAR-router-using-TFTP-client.
However, there has been no change in the router state. I tried both R8500-V1.0.2.136_1.0.99.chk and R8500-V1.0.2.144_1.0.99.chk.
Here is the log confirming successful transfer of the .chk file:
tftp> connect 192.168.1.1 tftp> status Connected to 192.168.1.1. tftp> put R8500-V1.0.2.136_1.0.99.chk putting R8500-V1.0.2.136_1.0.99.chk to 192.168.1.1:R8500-V1.0.2.136_1.0.99.chk [netascii] Sent 33029066 bytes in 152.1 seconds [1737229 bits/sec]
I'm out of ideas. Any suggestions on what I should try next?

That'd be the Power indicator? If so, then TFTP would be next step.

That was the clue.

Doh! Thanks for pointing that out. I got the router working now. Thank again!
Just an FYI
happenned here too with the 1.0.2.144 firmware
Ironically flashed one for someone remotely without issue, ours crashed and burned
The tftp recovery worked out fine though, just a bit of downtime
