Add on board not connecting to wifi

I had the original boards setup, but had problems with them stop working. I chaulked it up to power surge and ordered the new V2.

I have swapped boards using the same wiring. Main board works great.  Addon board attached to wifi fine, but after adding the wiring it doesn't connect to wifi and can't be "found" by smartthings.

If I unconnect the wires (glass breaks and window sensors), it works fine. 

What is going on???
