Music keeps cutting in and out

I am steaming music from my macbook air to my Audio359 (Raspberry Pi B+ with HifiBerry DAC+) wirelessly.
The macbook is about 4 meters away with a clear view.
The music plays very well, but then cuts out for some seconds then cuts back in. this can then go on for awhile.

Given I’m relatively new to this I am wondering if the issue is related to either the renowned macbook wifi issues or I should be powering off the audio359 more often than I do to help reset the connection…

Your advice is most welcome.

It’s almost certainly going to be related to this here:

I have the exact same issue and have done for a while now. No one has posted a response here about it at all sadly. I have no idea if it’s being fixed or not.
