I have the same problem. My HP Compaq 610 is running Windows 7 ultimate (32 bit), and I have an Intel Wi-fi 5100 Adapter.
I also have an Asus EeePC 900HA also running the same version of Windows.
I have no problems starting the VR, i have it installed on my primary laptop (Hp Compaq), and the network created with the VR, get shared to my netbook (the EeePC).
The netbook connects to the network but does not have internet access. But this is on my home PPPoE connection.
I also tried this at my work LAN connection which is not PPPoE (does not require password for access to the internet, just plug in the LAN cable and the internet is there) and when I started VR and created the virtual wireless network and also shared it
to my netbook, it had access to the internet.
A I guess the problem is that there are specific kind of LAN connection that allow the VR to share the internet also. Am I right? Am I doing anything wrong???
