6 google home and 2 chromecast... no more wifi at home
I too have a lot of trouble since a few weeks
I first suspected either one of my neighbours router overlaping my wifi channel, or a failure of my own router (I was near to buy a dedicated pro netgear router to replace the one from my internet provider (Sagem branded))
Then I saw all your comments....
Symptoms are the same as yours : times to times, my main 2,4Ghz SSID just disapears or stay there but is just unconnectable
So for now I'm only using one google home, the others are just picking up the dust, waiting for an update (Google or Sagem, who will be the first ?)
