I have a Polk Audio MagniFi Mini Home Theater Sound Bar System which is supposed to work with Google Home. Running the Google Home app on smartphone does not find a device. I don't know if it's the router or what. That is the only think I can think of that might be the problem. I have tried enabling guest accounts. No help. I have tried to make sure everything is on the same home network ... Phone, Polk device ... and they are.
Believe it or not, POLK support says there is a GOOGLE problem with Google Home both on IOS and Android and we have to Wait for Google to (hopefully) fix it. Sounds a little phony to me.
The only thing I could recommend that may help if it was a router issue would be to disable QoS completely in Anti-Bufferbloat settings. Try that and see what happens.
Other devices ... Uhm, .. well, various laptops, tablets, Smartphone, Alexa and Smart TV seem to. There is a Harmony Hub involved as well. I am not an expert in all this 'multiple device interoperability'.
Random idea, can you try enabling guest WiFi on the router and connecting to that? This worked before for someone having a problem with their NEST device
Yes, I tried that. No help BUT I think POLK isn't on a guest network at the moment. Not sure, but I think I have to change that on the Smart TV. Not sure. I am supposted to contact Polk in a week to see if Google has 'fixed' the problem. I will give that a try. Thank you.
