**************************
What I expected to happen:
**************************
I expect my windows 10 PC to be able to connect to a hotspot if I set one up

**********************
What happened instead:
**********************
It can't connect to the AP

***********************
Logs of when I connect:
***********************
wpa_supplicant[1358]: wlx00c0caab435c: CTRL-EVENT-SUBNET-STATUS-UPDATE status=0

... this is the only line that appears in the logs and on the windows machine, I get the very helpful description of "Can't connect"...

******************
What I did so far:
******************
I tried reading about the ap_scan modes what I could find.
The only two references I did find, was:
- that ap_mode is a setting you can set in wpa_supplicant, however, I'm using NetworkManager and I don't find a way to set 'ap_mode=1'
- all other references were bugreports, which led me to here.
I ordered a new Network Card, using a different chipset, to see if the problem persists. Sadly it didn't arrive yet.
