I've had a similar/same issue the last few weeks. I have several Nest Audio speakers, a Nest Mini, Nest Hub Max, Home Max speakers all of which worked fine for, well, forever. No changes at all have been made to my home wifi, network or modem settings and all of a sudden my google speakers all start playing up at the same time. As of a few weeks ago, sometimes just individually or half the house at a time, they would stop responding to any voice commands and cast rquests. Sometimes it would just be 1-2 speakers, the next day all except a pair of Next Audios. I have to power cycle them to get them working again. 24 hours later, they start dropping off and stop responding yet again. Ive rebooted the modem, tried changing the modem to single band 2.4g, same issue. Set modem back to dual band, same issue. Ive factory reset every single Nest speaker, set up as new again, they work for 24 hours then start dropping off again randomly. They all worked almost flawlessly for months on end, if not years, then all of a sudden the same issue impacting different types of next speakers and display all at once.
Reaching end of frustration levels with them and ready to throw them all down the bin shute soon if I can get them all back and working like they should! H E L P! 😣☠️
