Not that it helped me so far, but option-click on the Wi-Fi symbol shows an “enable wi-fi logging” menu item that fills a /var/log/wifi.log file with quite a lot of unhelpful messages. But they seem to indicate I may actually suffer from some password/auth/roaming problem

The worst thing: Occasionally it *does* connect, things work for a while, then crawl to a halt, then work again. I have no idea how to reproduce or even describe the issue to support except as “doesn’t work, most of the time”

21 devices in my house are connected to my UniFi wireless network; my macOS Mojave laptop, which was device #22 until last week, has stopped being able to connect. With more than 30 years of IT experience, I have absolutely no idea what to do about it

My guess is for the same reason some are proud of not knowing CSS or HTML. Or JavaScript. Or Java. Or Math.

Mein Kollege Christoph Iserlohn erklärt sehr schön anschaulich, wie eine Timing-Attacke funktioniert – und was man dagegen tun kann
"Der String-Vergleich über die Methode String#equals in Java ist anfällig für Timing-Angriffe. Der oft empfohlene Lösungsansatz ist schwierig korrekt zu implementieren (...) Die hier vorgestellte Methode schließt diese Probleme prinzipiell aus." @INNOQ
