My Apple devices started stating "incorrect password" for my network, even though they had conncted previously.

So how to fix Unifi network "incorrect password" error on iPhone, iPod, iPad and Macbook pro?

The reason for the error is the WiFi management done on iOS devices. 

The default settings for the Unifi AP range are not compatible with iOS 11 and 12 and OSX High Sierra (and maybe more). 

The reason for the error is the "DTIM Mode" (beacon timing) setting for power saving.
