With it being a point you already had, I would contact support either through phone or chat to see if you can get them to look more closely at your device. They'll have some tools to diagnose things directly. You can reach them here: https://goo.gle/31i1U5t. Just make sure to choose phone or chat as your method of contact and they can help you find a cause and solution. If you have any troubles reaching support, let me know.
The reply person from Google support about my problem was: "The Google Wifi point(setupXXXXX) that's no longer powering on, I regret saying that we've already covered all necessary steps to at least turn it to pulsing blue.".
Thus, I've basically a dead Goggle Wifi device. 😞
I will try to fill the form you suggest. Thank you again for your prompt help.
Just one quick final check in here since activity has slowed down. We haven't heard from you in a while so we'll be locking this thread if there is no update after 24 hours. If you have any new questions, updates or just a discussion topic, feel free to start a new thread in the Community.
I've just decided to give up from this Google Wifi point/router, and keep working with the other two until I will decide to acquire a new mesh network (probably from other vendor). Thank you all for your attention on my problem.
We're sad to see you go. We hope we can make it up to you in the future. Send us a message if you change your mind. Please let us know if you have any other questions or concerns as I will be locking this thread after 24 hours.
