Only found some ways to crack a WEP network, a bit difficult, haven't tried... There is no WEP key for accesing the network, so it would be no use...

Furthermore, I used gconftool -R /system/osso/connectivity/IAP
to find the IAP and try again to connect directly. It displays the configuration details of the saved connection. And instead of "EAP_PAP_username" it displays "EAP_MSCHAPV2_username". This is truly strange. Again, in the settings wizard it is configured as WPA with EAP, TTLS, EAP PAP.
Any ideas?
