3) What happens
When turning on hardware switch for wifi, the network manager doesn't
recognise the hardware (greyed entries for wifi).
4) What I expected
I expected it to recognise the wifi equipment and start scanning for wifi
networks.
5) More info
Strangely enough, while reporting this bug (on a wired connection), the
network manager started detecting wifi again.
I rebooted, and the bug came again.
I started reporting the bug, and the wired connection started again.
6) a few logs:
