HomePod and AirPlay 2

Hi,

The source media is coming from my iPhone 7plus. It doesn’t matter if I stream from Amazon, Apple, Pandora or play downloaded playlists from my phone, it still cuts out in the kitchen. This led me to the idea that if I switched the living room and the kitchen HomePod to see if the problem would follow the HomePod but it didn’t. The problem was still in the kitchen and like I said above, I have an extender in the kitchen now so it’s getting a good wifi signal. My router is built into my modem which is located in a guest room, hence the idea that I get the extender to give the HomePod a good signal to work with. I am going to try the idea of shutting off the 5GHz band, I don’t think it’s on but until I can get onto the modem, I won’t know for sure. I won’t be home until Wednesday and this is Tuesday to experiment with that. Thank you for your input. I welcome all ideas. :)
