We have a Sonos 1 with Alexa, a Sonos5 a playbar and some other sonos speakers. We also have a Nest cam. We connect these devices to the internet via a WIFI router- a Linksys WRT1900ACS wifi router. We also have a netgear extender upstairs to have a better signal up there. All of the sonos devices tap in to the Linksys WIFI, and the Nest cam connects to the extender WIFI. We will go long periods with no issues, and then the Sonos devices and the Nest cam will all stop connecting however the wifi is still working great. No reason to the disconnects. Rebooting router does not seem to help. And thn for no reason they will connect again. It makes me think we have something set up incorrectly but I don't know what, I thought it was as simple as they connect to wifi, but clearly I'm wrong. I have the 2.4 GHz signal on channel 6.
