What would be the best setup of a Nighthawk CAX30 and Nighthawk MR60 with the Two Sattelites?

Hello,

As the title says, what would be the best way to set both of these up? Have a one gig speed plan with Xfinity. CAX30 is currently in one side of the house which means the other side has dead spots. I have a long ethernet going from the CAX30 to the other side of the house. Would like to achieve the best connection possible without having multiple Wifi Signals. Just one wifi, where I can move around the house without dropping connection. 

UPDATE: I attempted using the CAX30 gateway, wifi on. Then using the MR60 mesh on AP Mode with the wifi also on. I named the wifis from the CAX30 and the MR60 the same. I was hoping that they would be compatible this way, but it was not.. Had bunch of issues. Mainly the DHCP server on the CAX30 does not play well. It assigned a bunch of devices the same IP address. Even after I made IP reservations.
