Hi,

I press "discard history" and shell.logs shows:

/usr/lib/python2.6/site-packages/dbus/connection.py:242: DeprecationWarning:
object.__init__() takes no parameters
  super(Connection, self).__init__(*args, **kwargs)
Traceback (most recent call last):
  File "/usr/share/sugar/extensions/cpsection/network/view.py", line 254, in
__network_configuration_reset_cb
    self._model.clear_networks()
  File "/usr/share/sugar/extensions/cpsection/network/model.py", line 120,
in clear_networks
    network.clear_wifi_connections()
  File "/usr/lib/python2.6/site-packages/jarabe/model/network.py", line 934,
in clear_wifi_connections
    _nm_settings.clear_wifi_connections()
  File "/usr/lib/python2.6/site-packages/jarabe/model/network.py", line 506,
in clear_wifi_connections
*    if conn.type == NM_CONNECTION_TYPE_802_11_WIRELESS:*
*AttributeError: 'NMSettingsConnection' object has no attribute 'type'*

If I switch "*conn.type*" to "*conn._settings.connection*" runs ok.

> User interface changes:
>
> - enable the disconnect button on the access point menu in the
>  neighbourhood view, (rather than the button doing nothing),
>
> - fix the disconnect button on the wireless device icon in the frame
>  so that the disconnection remains effective, (rather than
>  disconnecting and then reconnecting automatically),
>
> - enable the discard network history button in the network control
>  panel, which also now forces a disconnect, and will be insensitive
>  if there are no networks to be discarded, (rather than the button
>  doing nothing),
>
> - enforce consistency between the neighbourhood view, the frame, and
>  the control panel, with respect to how the access point is shown.
