Every home is different, so it is difficult to provide a universal guide that suits it all. What you can do is check the number of available access points in your home by performing a Wi-Fi network scan using a mobile device. Then select the Wi-Fi channel that isn't as busy as the rest. Also, check how much noise each speaker has using the Harman Kardon Controller app. Simply go into the settings menu and select "Send us feedback" to see the results, signals between -40 dB and -62 dB are considered good.
