@VikasMG I had similar issues with my Muso-2 on Wifi. It would disconnect itself after one day. I did not attempt to troubleshoot the issue as I was just experimenting with WiFi to compare sound quality vs. wired. It was disappointing because I never have issues with any of my other wireless devices. The Muso should just work! And if it does disconnect it should be able to reconnect itself. I understand your frustration. My Muso is normally on wired connection and I never have network problems. That is probably not an option for you. Maybe someone who has spent more time on this problem can help by posting here. In the meantime there is this general network troubleshooting page on the Naim site
I’m sorry I could not be more helpful. But at least you know there are others who have experienced your WiFi problems with the Muso-2.
