I am using Windows 7 with no software for my bluetooth (it came without) so I have the bluetooth device in Devices and Printers.

There I have the pairing with my N900 and I press Connect -> Direct Connection.

After it says "successful" in Network Connections the Bluetooth PAN shows "Connected to WorldKaoss", IP is set-up manually packets are sent but none recieved.

PC Connectivity in my settings (on the phone) by default was set on "None" so all the settings (Internet, Wlan, Bluetooth,etc) are disabled. Should I use the "Default" profile for the PC Connectivity Manager?
