Contour 2 not connecting to tv

I just switched to Contour 2 & a new Panoramic wifi,   The contour 2 boxes are wired with a coax cable.   The previous boxes & router everything worked great.

The internet is working, but the TV's do not connect.   I changed out boxes thinking it was the box but same error message comes up, check connections, etc.

I have done that a million times.  

If I was using coax before and everything was working.  Why isn't it working with these Contour 2 boxes?
