One would say "Internet Connection Sharing error. (5)" which I have no idea what that means, and it stops the installation of the hardware.
The other one is more confusing. It seems that the Hardware wizard would manage to install it, because I see an icon of two monitors with a yellow dot moving back and forth in my taskbar (hovering over it, there's a Status saying "Acquiring network address".
And then it says "This connection has limited or no connectivity." What's going on? It was working fine last time, and it didn't come up with this message before.
