Having a Mu-so 2 for over several years now, I had to reset the system several times in order to be able to control it with my I phone.
Recently I solved the problem by disabeling my router’s automatic band possibilities.
By blocking WiFi 2.4 and having only Wifi 5.0 as Wifi band all the problems have disapeared and is the system stable and in perfect working order
I’ll tell you what else seemas to mess up wifi which I’ve discovered recently during this stupid heatwave - if you place desktop fan between your laptop and line of sight to the wifi source, the spinning fan blades seem to have a disruptive effect and no, I’ve not been drinking.
I have configured separate SSID’s for 2.4 and 5.0 and that solved a lot of problems for me (also with Bluesound equipment).
Good solution too
