Title:
  wireless does not work on boot

Status in systemd package in Ubuntu:
  New

Bug description:
  I've setup a wireless config in /etc/netplan/config.yaml and it does
  not activate on boot. I have to run 'sudo netplan apply' to get my
  wireless connected. This works fine on an RPi4 but not an RPi3B.
