Can the wireless contour box work when your Panoramic router is in bridge mode?

I got a new contour wireless box because I was told it would work, but it does not work when I put the Panoramic router in bridge mode. I can watch recorded shows and see the Guide, but live tv does not work.

I assume it’s because of Cox’s use of the MoCA protocol.

So I am paying rent on a useless box. Can someone please confirm that it should or should not work?
