I understand the evolution of WiFi security if not all the details. My workplace has a couple WPA2-enterprise WiFi networks. Definitely not WPA3. I don’t think we have anything special because iThing/Android/laptop devices usually don’t need any adjustments from the default settings. Users just enter their credentials and go.
Years ago, some Windows machines would need to install/trust a non-standard root cert, but I haven’t seen that it a long time. Does the L5 not have any built-in, trusted root authorities?
