Using WPA-Enterprise, as I understand it, requires devices to be preconfigured to authenticate with the radius server, which makes it a non-starter for the kinds of networks that use a captive portal.
No, there's no preconfiguration needed, it's just a username/password account. You choose the network, then the OS asks you for your user/pass, then you're connected.
It's the router that connects to the RADIUS server, not the device directly. And some routers have one embedded, so you don't even need to configure that, it "just works".
