probe router wirelessly, double NAT

I'm having some trouble with vuze, so am looking at some networking.  The 
computer uses a wifi adapter to connect with the router.  The adapter is 
a bit unusual:

So the computer gets an IP address from the adapter, and the adapter gets 
an IP address from the router.  Presumably this is double-NAT?
