I have the same problem. Mydlink lite app on my iPhone worked fine until today.
It connects, i log in, shows the camera is online, but gets zero bit rate from the camera.
I upgraded to the new 2.6.0 and still does the same thing.
I can log into the the setup web interface just fine and see the video. It also sends emails with pics just fine.
But rather mydlink lite app on my iPhone will not get a picture even though it did yesterday and for 3 weeks prior.
Does anybody have any idea what it might be?
