My situation MIGHT be similar to this issue. It worked for me and during the process of making it work I experienced the same issue with the different versions of software I was using to test the cameras.
I have two(2) dlink 930L cameras. I purchased these cameras at different times from different vendors. Both were setup in MyDlink at one time and working in the wireless mode The camera were put into storage for about 6+ months.
I went to use the cameras, plugged them in and went to MyDlink and nothing was registered. Now I might have un-registered them somehow, I don’t remember.
So I started the registration process again.
1-Upgraded both cameras to the latest firmware 1.04
2-Attempted to register each to MyDlink with a wired connection. One registered the other camera could not be found using the autorun.exe registration wizard from the original disk. Did the hard reset stuff to factory defaults. No luck.
3-Installed SetupwizardSE-1.05 and used it to set up both camera. It found both the cameras either in wireless or in wired mode. Did all the IP setup stuff and other options I wanted. Viewed the camera from this software.
4- Downloaded the latest software version for the 930L and used that version to attempt to register the camera that was giving me issues . Still no luck, one was registered, the other would not be found by the registration software.
5- Finally after a couple nights of resets, different hub ports, cable changes, IP addresses and lots of other tricks I remembered something from the initial registration process months ago. I had changed my OS to Win7, prior was XP.
6-Using the original install disk, ran autorun.exe from an XP machine and bingo, it found the maverick camera, registered it to MyDlink and all is ok. It works fine now.
Anyone have any idea what magically forces may be working on this one?

I'm glad its over and everything is working. Gary
