DCS-936L Connection Problems
MikeSD:
This is the most difficult camera I've ever used from D-Link. I have several other models and never had any issues with them. Or installing them. They have been very reliable and easy to install. That is why I bought others.
I bought 2 of the DCS-936L because of the size and the fact I can easily power it from USB (i.e. a LiOn battery pack). But I can't get the MyDlink lite app on my Android to install them. I did manage to get both cameras to connect to my WiFi, using the WPS button. And I can directly connect, using the IP addresses. I also did port forwarding, so I can access both directly from the internet.
But can't get mydlink to see them. It appears the only way for the app and the MyDlink page to see them, is to go through the install process. But that fails, everytime. I get two kinds of failure.
* Unable to join the network (I have correct data on the cameras)
* Or an error that says to turn on WiFi on the phone (but it's on and I can see wifi) but app can't see the wifi for some reason
* I have done hard resets with same results
* I have uninstalled the app and reinstalled, with same results
* I have two cameras and both behave the same way
Anyone have this problem?

What FW is currently installed?
Can you install the cameras using a PC to initially set up the cameras and get them associated with MDL?
What Mfr and model router are you using?
Test cameras with uPnP and uPnP Port Forwarding both enabled on ALL cameras: DCS Cloud (L) Series Camera Configuration and Mydlink.com
I recommend setting a static IP address ON the cameras outside of the main host routers default DHCP IP address pool: DHCP

Firmware not issue. Have tried with what came with it and after upgrading. Same thing.

Nope, must go through the app, to install these. They don't have Ethernet connection. Must setup through app before I can access the internal web pages.

Linksys 1900AC. Not the problem.

That's what I do. I always set the IP to static outside the DHCP range, so that it never changes. But as soon as I change the IP, and port forwarding, it breaks the app setup. About the only thing that's working in the app is the initial Wi-Fi connection. Even though it says can't connect, it loads the parameters so I can see what the IP is on my router and set things up manually. HOWEVER, I lose the ability to use MyDlink with it, after the IP are set to static.
Before adding these two cameras my system was:
Camera 1: External Address:9040 --> 192.168.1.9040 (DCS-2330L)
Camera 2: External Address:9050 --> 192.168.1.9050 (DCS-2330L)
Camera 3: External Address:9060 --> 192.168.1.9060 (DCS-5222L)
Storage 1: External Address: 9099 --> 192.168.1.9099 (DNR-312L)
I then tried to add 2 of the 936L cameras to get
Camera 1: External Address:9040 --> 192.168.1.9040 (DCS-2330L)
Camera 2: External Address:9050 --> 192.168.1.9050 (DCS-2330L)
Camera 3: External Address:9060 --> 192.168.1.9060 (DCS-5222L)
Storage 1: External Address: 9099 --> 192.168.1.9099 (DNR-312L)
Camera 4: External Address: 9045 --> 192.168.1.9045 (DCS-936L) or 192.168.1.47 (port 80. System seems to work better with port 80)
Camera 5: External Address: 9047 --> 192.168.1.9047 (DCS-936L) or 192.168.1.47 (port 80. System seems to work better with port 80)
But as soon as I change to a static IP, things start to break. Mostly my MyDlink page no longer works on the PC and my smart phone only works local.
MikeSD:
The thing that's so frustrating is that I can get this (changed ports slightly for consistency):
Camera 1: External Address:9040 --> 192.168.1.9040 (DCS-2330L)
Camera 2: External Address:9050 --> 192.168.1.9050 (DCS-2330L)
Camera 3: External Address:9060 --> 192.168.1.9060 (DCS-5222L)
Storage 1: External Address: 9099 --> 192.168.1.9099 (DNR-312L)
Camera 4: External Address: 9046 --> 192.168.1.46 (port 80)
Camera 5: External Address: 9056 --> 192.168.1.56 (port 80)
That works fine direct access, either remotely or locally. And seems to work ok LOCAL with mydlink LITE but nothing from the web MyDlink or REMOTE with the LITE app.
And there doesn't seem to be any way to get these working, without going through the install process, using the APP. And that's where the failures occur.
There isn't any way to specify any of the ports, during setup. So they were changed by direct connection to camera, after install. Before changing ports, the MyDlink worked. But after I changed ports, they couldn't be connected to. That led me to think these cameras have to be on port 80 by default. But that doesn't seem to fix the problem either.
All the other cameras had the ports changed after the install wizard and they still continued to work. Just not sure how the web form, or the smart phone app can know the ports, except from the cameras themselves. Somehow that information was transferred to the Remote access software ONLY at the install point. Anything changed after, loses that connection. At least that's the way it appears to work.
This is my setup and you can see what part isn't working.
External Port 9046 forwards to internal IP:80 and 4056 forwards to internal IP:80. The other cameras forward to ports other than 80. But I have tried using internal ports 9046 and 9056 with same results as using 80. I'm stumped.
This is my LOCAL and REMOTE screen on my phone
This is MyDlink page from PC
I have the LOCAL and direct accesses working. I'd think the app should be able to scan the local cameras and just transfer the into to the MyDlink website OR use it for the remote access. Seems to have all the info it needs. But doesn't seem to work that way.
The other thing I wonder about is why there are two "Add a New Camera" one for Remote and one for Local. Seems that one should be enough. During the install, sometimes the Local setup would ask if I wanted to use the info for mydlink (remote I assume). But it didn't always do that.

Problem solved: Duh!
Actually, not really a duh! I still am not entirely sure why but it kind of makes sense. I was wondering how the MyDlink web site would possibly know what the internal port routing was. Either it had to be passed during install OR there had to be another way for it to know, outside of the camera. So I started looking at differences between what was working and what was not. I noticed a field in the Static IP setup that was blank, on the non-working cameras.
This field was: Optional Primary DNS
On the other cameras, this field is filled in automatically, by default. On my 936L, it's left blank by default. I just entered 192.168.1.1 like on my other working cameras and everything started working.
I think I've spent about 15 hours on this. It would be time well spent, but I'll probably forget about this, in a day or two. ;)
