Naim Network readers 1st generation Audirvana parameters

Hi, I run Audirvana Studio on a Mac Mini to feed a Naim NDS with Qobuz. Previously using mConnect I had regular hang-ups.
I still have hang-ups.
Not every minute but quite frequent.
It seems that it has something to do with general internet load because I have more hang-ups in the evening or during week-ends.
Has anyone completely overcome the hang-ups with a Naim ND5XS, NDX or NDS? And in that case, could we share all Audirvana parameters?
Best
