Regular TV channels don’t work on wireless

I just installed the Contour Wireless box on my patio.  Everything works (the guide, OnDemand, apps) on it except for regular TV channels.

Further when a TV channel is selected, or when an OnDemand option is exited, the device will crash with an error message.  I expect that this is happening when it tries to got the TV channel that is active.

I read elsewhere about some MoCA setting that needs to be enabled.  But I cannot find this setting on my modem/router, utilizing the CoxWiFi app.

Any idea where to enable this setting?
