For a weird reason my N9 has no internet access when connected to my wifi network. Other N9's access internet fine on the same wifi, and this one can connect to other networks. I just changed the router with a brand new one, so it must be something in the N9.

Deleting the connection on the N9 from gui didn't help, neither doing it via gconf (gconftool-2 --recursive-unset /system/osso/connectivity/IAP/<connection-id>)

So the question is how do I reset *all* connection information from the N9?
