Can not find specified network name

I have read everything on this topic numerous times, including your article, and have done everything suggested. However, 3 out of 3 cameras continue to get this error message. The situation I need the camera for is urgent, and I don’t know what to do, as day by day either I or someone I recruit to help me has same problem. Are live support and chat myths here at wyzecam? I tried to send in request for help but only received article link with question as to whether I read it and did it help, with only one option for reply, which was Yes, and my answer was NO.
