Dead WiFi device

[dn325]

One of my 3 devices has died within the first week of use. 
This is the icing on the cake after harrowing setup troubles (no NOT connect your wired back-haul during setup! Only afterwards), and dismal throughput using PPPoE (210 Mbps on a 1G fiber line). 
Now, when trying to activate my warranty in hope of getting a replacement unit, Google’s warranty site finds no devices in my home and doesn’t accept my serial number (seems invalid). 
I thought I was upgrading, but my experience has been a serious downgrade in every which way. 
Any help I’d appreciated. Tia

Hi dn325,

Thank you for posting here in the community. I'm sorry that your Nest WiFi doesn't power up. This could be frustrating, especially if you recently purchased your Nest WiFi and nobody can't help you with the replacement. Help's here.

I just want to confirm if you took troubleshooting steps before moving to a replacement option. There are a few links to check for additional options to try first:

Please do the following: Factory Reset your WiFi device, then check if it shows a WiFi device light. After that, set up the Google Nest Wifi or Google Wifi again.

Keep me posted. I'll look forward to your response.

Regards,

Byron

Hi Byron,

Thanks for your assistance. 
I have tried manually resetting the device per your instructions. The device is literally dead. 
I have also tried the following:

- connecting the power supply of the “dead” unit to a unit that is working. The working unit continues to work, indication that the power supply is not the problem. 
- connecting the “dead” unit to a working power supply from a different unit. The “dead” unit does not show any sign of life, indicating that it is indeed dead. 
How should I proceed?
