I bought the DCS-932L today for my Mac OS X 10.6.8.
Have the Mac OS setup downloaded from D-Link (not on the CD) means not much though is needed for the registration on the mydlink site.
in any case, the exact steps to connect wirelessly and successfully, hoping you find the gap:
1- downloaded the mydlink setup utility for mac, http://www.dlink.com/mydlinkmac
2- connect the device LAN cable to the DCS-932L
3- connect the LAN to the free LAN port on my Airport (I use closed network, also a 5GHZ but first need a wired setup).
4- plug it into the AC outlet
5- pressed that blue light WPS at the back, I think it could have been done later (wifi) but you won't lose it
6- wait for the green light
7- start the utility, it will simply recognize the device and route to the site address, I guess it creates a site for that device number, registration required.
8- log onto mydlink.com to set up the network (I guess, you know the network steps as IT mgr)
9- left it on DHCP and enabled UPnP port forwarding - not sure why this was needed but SAVE
10- enabled wireless, it did NOT find the 5GHZ network but found the regular 801.11n - SAVE
11- just for checking I looked at the picture, then I disconnected and went nuts for a while, not connected but then I moved it downstairs (wireless) where I wanted, anyway, and WAITED 2-3 minutes (!) . No kidding, after that it found itself.
I think you just have to wait.
