I have not been able to connect consistently to my Nova. I have carried out all the recommended steps for both the Nova and Muso more than once.
I have had several issues including getting nowhere like yourself. Further to the above Naim support have suggested making sure you connect on the 2.4ghz channel - I do not think this has made any difference for me.
I set a static ip address for the Nova last Friday and things have improved - no idea why or how. But this might be a coincidence and a temporary success. Naim support have advised I have done all I can and are pinning their hopes on new app currnetly in beta. Not sure when it goign to arrive.
I have been using bubbleupnp pretty successfully to use Qobuz streaming and connect to my synology NAS. Radio wise using Tunein.
I have friends new to streaming for which the Muso sounds ideal BUT can I really recommend. They are not techie at all but then they have Apple gear so perhaps will be ok...
Sorry I cannot offer any more.
