I have been having this issue forever. I have tried different routers, even had all the cameras in one location 10 feet from the router, reboot, new firmware....nothing helps.
ALL the cameras drop out. Not all at once. They just randomly drop. Then they might come back in a minute, maybe not for hours, maybe never until I reboot the camera. Sometimes that doesn't even work. I have to re-set up the camera as a new camera.
This is a pain in the ass.
Any fixes for this?
EDIT.....I was going to attach a picture but I can't seem to do that on this forum.
