Contour 4K Wireless box

I have the Cox Wireless 4K Streaming box. Model Xi6-A. 

I keep getting this error 

It started a few months back with one of my boxes. So I returned it to the COX store and got a new one.

Then the new box started to do the same thing. I have 2 other boxes same model and they work fine. My Pano modem is just fine, not connection issues at all. I would take this box to the store and get a new one, but worried that it will happen with the new one too.
