Somehow mine starting behaving fine again, so I decided not to look a gift horse in the mouth, and let it go.
I wrote the seller (who has been very responsive) and she said that I have the latest firmware and that the previous firmware didn't have the WiFi in it, so I wouldn't want to take a step back.....
At this point I am OK with the camera, I just wish it had an easy way to embed the stream into a webpage, but it doesn't look like it will be straightforward. I was able to login over telnet, but didn't see anything obvious when poking around.
I think I will probably have to take the rtsp stream in on a machine, convert to something html5 appropriate with ffmpeg, and host that up...
