Possible issue with certain wifi card drivers
Possible issue with certain wifi card drivers causes only adhoc with WEP encryption be available.
It is also possible that some of the wifi cards do not support AP (access point) mode of operation by design
sudo iw list |grep -i "Supported interface modes:" -A10
It is also known that wpasupplicant_2.10 is misbehaving when WPA/WPA2 personal encryption is chosen.
To check version of installed wpasupplicant:
wpa_supplicant -v
Thus, wpasupplicant_2.9 and corresponding libssl1 need to be installed prior to activating built-in hotspot feature
Then, to avoid wpasupplicant from being automatically upgraded, it needs to be put on hold with the repositories:
sudo apt-mark hold wpasupplicant
It has also been observed, that hotspot may start with a hidden SSID, thus to make it visible:
sudo nmcli connection modify Hotspot wifi.hidden 0
Then, to see if any client successfully authenticated
ip neigh show or arp -a
