When I am trying to create a Wi-Fi hotspot that should offer a WPA3 Personal encryption, all CPUs are running mad for a few seconds before Ubuntu tells me that the creation of the hotspot failed. Everything works fine when I am using WPA & WPA2 Personal encryption but I would like to avoid that type of encryption.
What can I do in order to solve the problem?
WPA3 is not supported on your wireless adapter.
From this answer: you can check its model with
sudo lshw -C network
