I have 5 mini speakers and a hub max. I have 2 google wifi, router and a point connected to xfinity modem/router. I have trouble creating speaker groups. I can only see some speakers but not orhers. I noticed some speakers are connected to LAN, others to WAN (???). I am pretty new to HA, so I'm not sure if I'm explaining it correctly. It seems that depending on my location at home only specific speakers show up. My house is not more than 22000sqf.
Thanks for posting. That certainly isn't the experience we want you to have ― let's take a look at it. May I know if you have 5 Google Home Minis or 5 Nest Minis? How far are your Nest speakers from your main router? Are all of them on the same Wi-Fi network? It would help a lot if you could do a sequential reboot first. Unplug the power cord of your modem then your router followed by your Nest speakers. Plug them back in after 3 minutes or 5 minutes tops. Restarting your phone might also help. Make sure all your devices are on the same Wi-Fi network. Here's how to check them. After checking one by one, delete your current speaker group and recreate another. Tell us how it goes.
