Qt mobility Bearer error when search for WLAN

Hi !

I use the code below to save the IAP when connecting to the network:

QNetworkConfigurationManager manager;
const bool selectIap = (manager.capabilities()& QNetworkConfigurationManager::CanStartAndStopInterfaces);
QNetworkConfiguration defaultIap = manager.defaultConfiguration();

if(!defaultIap.isValid() && (!selectIap && defaultIap.state() != QNetworkConfiguration::Active))
{
	// let the user know that there is no access point available
}
session = new QNetworkSession(defaultIap,this);
session->open();

Everything works fine when I select the Access Point from the popup list. But if you select Search for WLAN and select a WLAN that QNetworkSession always return State == QNetworkSession:: Disconnected. When the Connect Manager in device reported that the WLAN is connected and active.

I'm using : S60_3rd_FP2_SDK_v1.1
qt-symbian-opensource-4.6.2
Carbide.c++_v2.6
qt-mobility-symbian-opensource-1.0.0
I have tested in Nokia E63 and E71
