Hi Matthias,

I'm not subscribed to wireless@, so only posting on net at .

It seems like these networks don't use WPA, so I assume they use a
captive portal[0] instead. iPhone and mac have agents to pick those up
automatically (CaptiveNetworkAgent).

Which would mean, that you would connect without WPA and simply enter a
website like http://neverssl.com into the browser (or a random IP
address like http://10.1.1.1), which should then bring up the captive
webpage, which should allow your son to enter the credentials (pretty
much like you would do on hotel wifi).

Cheers,
Michael
