Wireless networking randomly disabled

I know it’s not a major problem for developers as it seems to only happen to me. I use Volumio 3, latest version. Also in another room Volumio 2. I never had the problem I report on Volumio 2, it started with Volumio 3, and it goes on: wireless networking randomly disabled. I turn it back on and it randomly turns off again.
This doesn’t happen on my other system connected to the same network and with Volumio 2.
Assuming it’s a problem with my installation, I’d feel great if someone suggested a solution, having a weird problem might encourage knowledgeable people to get involved.
