Close to as I can inform, when macOS places the screens to sleep as a result of inactivity, the WiFi drops.
Can it … not?
(Be aware: we’re plugged in the complete time. I am not sleeping the laptop computer, I am not closing the lid, I am standing as much as stretch my legs and coming again to search out something that required Web has died as a result of I used to be gone about lengthy sufficient for the screens to show off.)
