I completely agree with you on root cause analysis as this is what I do for a living tracking down systems problems and process problems within three large data centers that control the flow of trillions of dollars a day.

I have tried everything listed above to answer DJ question the camera stops working first then 60% of time the connection Wi-Fi drops after that.

I have top quality network hardware with more than enough bandwidth the router this is connecting to is 5 feet away from it.  I am having this issue no matter what the power source is my UBEC’s or bench power supply I am having the issue connected to the IOTiny or any of the other two EZB4’s with nothing else connected to them.  I have tested the cable that came with it and re crimped each connector. I also made a new cable and tried that and had the same results.  Sometimes it seems to work ok for a bit and then stops.

The only thing that I have not changed out is the camera itself.

@Redzone, thanks for this post this is the only thing I have not tried I will give that a try and see if it makes any difference.

okay, the camera and wifi are not related. The wifi and camera have no relationship with each other. What I mean is, if the camera stops working or is disconnected, the wifi will not disconnect. The wifi will maintain a connection for ever, even if the camera is disconnected.

But I need clarity on this statement you made. I want to see if you accidentally meant something different.

It sounds like everything that you are using (IOTiny and EZB) are behaving the same way. Is that what you meant?

DJ yes that is what I mean the camera freezes and stops and you can’t restart it unless you turn off everything and start them up again.  No matter what board you use with nothing else connected to it.  This also holds true when they are connected to the bench power supply or the bench power supply is connected to the UBEC’s connected to the boards.  I miss spoke on the Wi-Fi disconnect percentage as I was also dealing with the MPU6050 causing the ezb4’s to disconnect from the Wi-Fi during this same timeframe. I had said 60% it is more like 30% for just the camera testing.   I know you said they are not related but it does not change the fact that it happened while testing.

DJ, also just to be clear this happens both in client mode or AP mode.

Well, it sounds to me like the only common denominator in all this is the camera. Seems like you have tested everything and in every way. If it were me I'd get a different camera and cable and see if that solves the issue.

@Dave,  I have ordered the new camera and cable already just waiting for it to get here.  I also ordered some Super Caps to try that solution also they should be here tomorrow I think. This sounds like it maybe just a good thing to do anyway even if it is not the solution for this issue.  So more to come...

Well another update I tried the super cap solution today and have the same problem so that did not address the problem so now I wait for the new camera and cable to get here.   More to come soon...
