@Elijah, as I had a similar question a long time ago (Captive Portal) I would be interested in your success
One idea I had, but never tested, was to use a router with “Client Mode” where each request that comes from any device linked to this router gets passed to the WiFi AP with the router’s MAC/IP and so it should be possible to hook up the router to the captive portal by just initially clicking through the CP using another device (e. g. Laptop, Mobile Phone, Tablet, …) and so the router should provide its connection to the Core.
The only problem I had with this, is that I can’t find a router that does WiFi in both directions. The router I have does sport “Client Mode” and does work as outlined above, but only for devices hooked up to it via RJ45 and not via WiFi, since it does not support two SSIDs which it would need to (one SSID provided by the desired host AP and one it provides to its own clients like the Core).
It would be great if anybody knew a device doing this
In my special case, it’d not only be a matter of checking a checkbox, but my desired host CP uses an https-site and requires User/Pwd input, where the SSL might be a bit much for the Core to handle. So I guess there won’t be a Core-only solution to this - or will there
