I came home from a week-long vacation to find that my Wi-Fi was not working. Upon further inspection, my R6400 was spontaneously flashing it's various LEDs. When I rebooted it it appeared to boot like normal, but the power LED stayed amber, and all the ethernet + WAN port LEDs stayed amber. After about a minute the power LED went off and the ethernet ports and USB ports flashed very quickly as follows: usb1 = white, usb2 = white, eth1 = orange, eth2 = white eth3=white eth4 = orange.
I tried a 30/30/30 reset, I tried nmrpflash, I tried TFTP, and I tried holding the reset button for 90 seconds like another form suggested. Nothing worked!
Does anyone know what the problem could be? If it's a hardware-related issue could it be something easy to fix like a dead capacitor or burnt traces? Is it something wrong with the power adapter?
Re: R6400 Power LED Stays Amber Then Flashes Randomly
No, unfortunately this router hasn't gotten a firmware update since 2022, so it most-likely was not bricked by that. Plus, if that was the case, nmrpflash would have worked as it has for everyone else with that problem.
