The following item in Power…Settings… states:
Wi-Fi can be turned off to save power
You can see that the option is currently turned on. That should mean that the system is allowed to turn off the Wi-Fi to save power.
However, when I turn off that option, my Wi-Fi is disabled (turned off).
I'm attempting to tell the system that it is not allowed to turn off Wi-Fi to save power.
However, when I turn off the option it actually turns off the Wi-Fi.
It's seems that this item is not described properly in the Power….Settings…
Note: This option was the same under Ubuntu 18.04 also.

That's not what it means. Turning that off turns the WI-FI off, not the computer's ability to turn Wi-Fi off. It has the "turning Wi-Fi off can save power" subtitle to tell you why you might want to turn Wi-Fi off. Just leave it on if you want Wi-Fi, or off if you don't.
