The Router was set to WPA/WPA2 and I changed it to: WPA2/WPA3-PSK/SAE
Now it is showing as a regular Wifi AP/Router connection on the windows Networking Wizard. It still asked me for a Password, but the connection remains solid and does not disconnect.
Win11 has problems with wpa3. When you change wifi key, you have to forget the network in your windows then conenct again. Otherwise it will report wrong wifi key even it is correct.
