Is this normal?</STRONG> I get the same behaviour (using a USB ethernet adapter) on an Android device.</P><P>In the Smart Hub 2 Advanced > IPv6 > Configuration page there is an option for IPv6 allocation mode (Stateless, Stateful, Both, Off). If I chose "Both" then my WiFi connected Windows machine gets an IPv6 address.
