   Which "the Netgear genie"?  Ever helpful, Netgear uses the name
"Genie" for more than one thing.  Netgear routers have a web-browser
interface called "Genie", and Netgear offers application programs for
various computers/tablets/phones, which are also called "Genie".  (I'd
stick with the web-browser interface.)

   Visit http://netgear.com/support , put in your model number, and look
for Documentation.  Get the User Manual.  Read.  Look for "UPnP".
