Tks for your message
Did you factory reset the cameras, the manually load FW, then factory reset once more then set up from scratch with out loading any saved config files? YES, although I did reload config files - I will not start again from scratch, all this is SO TIME-CONSUMING
Are the 2330Ls online with the other 4 cameras at the same time?? YES, 3 on one AP, 3 on another AP. APs are on different channels and I believe I have not much interference from neighbours
Are these cameras out side or inside in some location? 2xDCS2330L outside, 4xDCS2132L inside
What region are you located? Europe, Belgium
If you can't get v1.12 working, then try v1.02 or the last known working version of FW. Yes, what a pain. Cameras are by definition 'out of reach'
If any of this fails, I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email. Not easy from Europe, will have to convince 1st level support that I have tried all obvious options. Not thrilled to spend hours on the phone. My diagnostic is really a fault in the firmware, as the image gets disconnected but access to the config is still possible through IP. And most of the time, the image goes back by resetting the image defaults
Let us know how it goes please. Will do, probably will revert to old firmware and live with its quirks, including inoperant mydlink.com ('pls update your firmware')
