Re: network-manager takes 1-4 restarts in order to recognize and connect to already-configured wifi network, USB dongle NIC

I do not have any other interfaces in /etc/network/interfaces, besides lo.

Thanks for the tip about systemctl -l status network-manager. There is a difference.

I ran systemctl -l status network-manager on two boots. In both cases, the USB dongle was already plugged in and was not touched. The first boot, I logged into Mate, and the wifi connected automatically:
● NetworkManager.service - Network Manager
     Loaded: loaded (/lib/systemd/system/NetworkManager.service; enabled; vendor preset: enabled)

             └─584 /usr/sbin/NetworkManager --no-daemon

...

Now the boot where network-manager repeatedly asked for the same password:
