'network manager' might think it has a connection (e.g. DNS resolution into the INTERNET works fine) .. but without login to the WLAN, all attempts (e.g. by the update manager, etc.) to contact .. http://ubuntuupdate.somewebsite.somedomain .. will lead to the webserver of the WLAN provider responding with his login page .. maybe the update manager is not checking for the information source and taking the response from the WLAN provider webserver as package update information ?

That's precisely what Windows does.

I've forwarded you the email dicsussion of this very topic, off-list.
Hopefully, it sheds a little light on how it currently works and
what's going to be done to make it a little more resilient.
