After I complete a new mobile broadband connection, the dialog for input mobile broadband password is showed (see the attachment file). The "Connect" button can not be pressed unless anything is filled in the dialog.

But if I fill anything and press "Connect", the connection can not be established, and I get an error message in daemon.log. The error message is like blew.

May 13 10:02:41 athena NetworkManager[902]: (NetworkManager:902): NetworkManager-wwan-CRITICAL **: modem_prepare_result: assertion 'state == NM_DEVICE_STATE_PREPARE' failed


My laptop is Thinkpad X1 carbon 4th Gen with Debian testing, the mobile broadband slot is embed.

Thanks to everyone!
