Welcome the Nevo club. :-)

I haven't programmed a NevoSL in quite some time, but I'm pretty sure that it does not support WPA. So I think you'll have to lower your encryption setting to WEP if you want to use UPnP control.

I had a few sites were I installed a NevoSL controlling content through UPnP, but I remember having a hard time finding the right combination of devices for the server and player. After some time, I found that the most reliable solution was to use that Nevo Media software that came with the NevoSL and install that onto a PC. Other than that, I did use a D-Link Media Lounge and a Roku M1000 at one point, but I think those players required the NevoSL never to go to sleep or the next song wouldn't play. But like I said, using the Nevo software on a PC was my favorite option.
