Not having found a thread where my issue is discussed, I've decided to create a new one. I have a Mac Pro 5,1 with dual boot (High Sierra + Mojave). Up until today, both operating systems have worked just fine. Since this evening, however, Mojave no longer recognizes the Wi-Fi card, whereas High Sierra has no problem with it. Since this isn't a hardware issue, I have to conclude that something has gone horribly wrong in Mojave, and this happened out of the blue, without any clumsy action I might have carried out. Continuity/Apple Watch Unlock, etcetera, have disappeared, and naturally, I can't see my own Wi-Fi network. Short a full restore, is there anything specific I might try to make Mojave recognize my Wi-Fi card? Not that it is particularly relevant, but my card is a Broadcom BCM94360CD.
 
I can't speak for everyone, but when i tickened around with my Macbook Pro in the past i had the same issue... To me, it sound the most relative, as it doesn't sound logic to some hardware just dceides to give up the "ghost" without some link to it in the first place which causes the issue.

First, i would boot to "recovery" and see if it shows there... If it does, its an account issue

Command+R to local recovery.

However perhaps there is a fix: http://osxdaily.com/2016/07/11/fix-wi-fi-no-hardware-installed-error-mac/

Safe boot (hold down SHIFT as power on til you see Apple logo) would load minimal divers, but best to go via recovery as you'll know nothing can interfere.

Thanks. Unfortunately, I've done both things. Mojave in its entirety says there is no Wi-Fi hardware, and that includes Safe Boot and Recovery. But if I boot to High Sierra, the hardware is still there, and it is working flawlessly! I'm almost certain that if I were to recover my latest backup, the situation would be solved, but that will take a lot of time.

EDIT: The problem has been partially solved using the latest Mojave combo update. Handoff is, in theory, activated, but doesn't work.
