You mention that you downloaded the latest "install software", I presume you are referring to the "Setup Wizard" software located on the mydlink.com/support download page. Is your DCS-942L firmware also updated to the latest version to match the Wizard?
Since you canceled my previous post for being a bite rude in saying the truth, I will try to be polite.
I guess that he (aek) has done the same thing as I have done, that is, upgrading every piece of software to the latest official version.
And YES, although all of us upgraded to the latest official version, the same problem keeps occurring.
Since my DCS-942L revision is A1, I have downloaded the latest firmware (1.21.2811) and the latest Windows Setup Wizard (1.01) from the official product page.
They are not working!
What I had to do to succeed was to download and install the firmware 1.22.2825, download the Setup Wizard 1.02.10 (from here http://tsd.dlink.com.tw/downloads2008detail.asp which is not for revision A1 cameras but for revision A4 cameras).
Then I launched the Wizard, it told me that there was a newer version (which I downloaded from within the wizard, it's the 1.04.02 version ).
And finally all went ok
So the question is WHY d-link does not address this problem the right way and keeps let's their paying customers live this nightmare?
