At a conference as we speak. Have a small embedded device running Debian that has no GUI. Trying to connect to confrence wifi which is open, i.e. no security, but has a type of web portal login page with a pre shared key. Because this is "upper layer", I don’t think there is anyway to "quickly" configure the interface to login to the portal. Or is there a way?
We can't put a GUI/web browser on this device and we have limited resources at this confrence.
