Every day for the past couple days, my WiFi on my MacPro 2013 running Mojave 10.14.6 has spontaneously vanished. The signal strength icon in the menu bar goes gray, and the status is "Wi-Fi looking for networks" (even though it lists all of my local networks).
The only solution is to reboot the machine.
Beside simply this random crass behavior, is there perhaps something in the logs I could look at that would show some tell tales that this is, indeed, what's happening? I would like perchance some additional evidence before I drag it in to the Genius Bar with "yea is sometimes does this" to try and narrow down the issue.
In the end, they may simply swap out the card. I don't know if it will fail a diagnostic, or if it's just happy happy until it decides "No, not happy".
