It's seems like this is a game of roulette. I have three DCS-932L using UPNP and the router is setup for it also. All three cameras have a green check. Using myDlink outside the house is a gamble, sometimes they can connect to the video, sometimes they cannot. One that is connecting early in the day, won't later, but will again tomorrow.
While inside the house, connecting is no problem. Through my Dlink or not, they stream just fine so it is not a wireless connectivity issue. They also work for motion sensing via email and schedule snapshot via email. There is nothing else connected to this router when I am not there. Only three wireless cameras.
Any ideas?
Thanks.
