I think I finally understood what you meant by querying the right properties.
I still can't find which class has the properties you listed. But I did
find that using "NetConnectionID LIKE 'Wireless%'" as part of the query for
the SelectQuery in C#'s WMI namespace appropriately only showed wireless
devices. Yaaaay!

Here is the code for C#:

SelectQuery select = new SelectQuery("Win32_NetworkAdapter",
"NetConnectionID LIKE 'Wireless%'");

Thanks for your help!
