I have 6 google home/nest speakers and one display hub. They've all been connected in the past and worked well. At some point one of my nest audios and one of my nest minis became disconnected and WILL NOT reconnect to wifi no matter what I try. The rest of my speakers (one of which is the original Google Home speaker from 2016 and original Home Hub, from 2018 I think) still work fine. I've tried factory resetting the trouble devices multiple times each and I still cannot connect them? At what point is it on Google to replace these devices that I paid for and cannot use?
Sorry to hear about the trouble. I wanted to follow up and see if I could be of any help. I found an article with some details on how to reconnect that. Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further.
Thanks AndroiFy for the helpful reply.
