Do I have bad hardware?

I have a 12 zone setup. With the primary board attached, I have 4 zones setup as I just started wiring things. I decided, just get add-on in place to start adding some zones to the second board. In my Netgear view I see:

After a few minutes the 0342 node drops off of the network. If I pull the power to the add-on board which is using this wireless module, it shows up again for a few minutes but drops out again after few minutes. I think the wireless module is probably the culprit.

Any thoughts before I open a ticket on things to try?
