The Networks are Not WPA3:
This messages all pertains to encryption protocol being used for the network. WPA2 is no longer considered secure. So, you need to use a WiFi network that uses WPA3. If you were to have your own network, and have much older devices (ones that don't support WPA3), then you's need to enable WPA2/WPA3. So, have the owner of the network enable WPA2/WPA3.
