I have an issue with the current Naim app.
I can initiate the Naim app, select my Muso (Gen 1) and choose any of my presets, Tidal / Spotify etc. Muso begins streaming but after a period of time (varies) the Naim app loses the Muso. Goes into a search mode but always come back with a whole load of blurb. Bottom line is it can’t find the Muso. While this is happening the Muso is still happily streaming my previous choise. If I reboot the app, it still cannot find the Muso. If I reboot my Android phone and restart the app all is well, until the next time. I have ensured that the Muso and Phone are at the latest code releases. I have also reset the Muso and redefined the network settings to ensure the phone and Muso are on the same network. They already were but I went through the motions anyway. It may be my imagination but I think this issue only started after the Naim / Focal merged app dropped.
Make sure your phone is on 2.4 GHz WiFi and not 5. Even though it’s the same WiFi network, it seems there are challenges with the phone (app) and a muso communicating with each other across 2.4/5GHz connections.
Always best to wire your muso to the network if at all possible.
It does depend on the router. There is no problem doing that with a Virgin Media Suoerhub 2ac for example, nor with an Apple Extreme router configured as a two band wireless access point.
I’ll take a look at your frequency suggestion. Thanks. Unfortunately, my Muso is situated in my conservatory. To far away from my router for a convenient ethernet connection. I did try powerline devices but there is an issue with the conservatory electrics being on a separate circuit breaker box from the rest of the house. I also for a while had a wired connection to a mesh disc. Of course that made no difference.
Mesh networks are problematic when they are incorrectly configured or located. A properly functioning mesh home network is very reliable and that, with a wire to the Muso, would be my recommendation if you can’t manage an Ethernet cable direct to your router.
