The CBK752 is WiFi, no MoCA option (the central unit has ethernet jacks, but you would have to run CAT 6 cable through your house.
Is your house wired with coax? If so, take advantage of MoCA (multimedia over coax).
I have found the MoCA feature in Cox's Panoramic modem (CGM4141) disables itself nightly and with each reboot (and no official answer from Cox, in my area, as to why).
Any suped up DOCSIS 3.1 modem/router with 32/8 channels, WiFi 6 and a MoCA option will do (plus a free phone modem from Cox). Add a few Actiontec Network Extenders (WCB6200Q) connected to any coax outlet and it's WiFi is like standing next to your router or sling a little CAT 6 ethernet cable to your PC from the WBC (up to about 165' per run can still deliver 10Gbps) and you will get about 90% of the speed you are paying for without the WiFi slowdown... That's 135 Mbps in your garage while you pedal away...
