Orbi RBK752 with Netgear Nighthawk CM1200
Hi There, I've been at this for about 4 hours now, trying to fix this on my own, but having no luck. So the internet went out, and when I tried to check things, I discovered the Orbi states there...
Yes, LAG is enabled.
The Orbi is connected to the modem (sorry for the incorrect terminology - I do know the Orbi is the router) connected in the first ethernet port.
I've done the powering off of the modem several times - even got Comcast in there to do a fresh reboot on it. Every time I walk through the setup wizard through the app, it will not finish because there's "no internet connection".
When I use an ethernet cable hooked to my Mac (I don't own a PC), I can get to the admin page (finally), but the NTP is weird, because it says it's "May 4, 2020" (which it is not - and now I'm getting a message that says "Warning: The Router failed to connect to NTP server, please check your internet connectivity or try another NTP server" - this happens whether I use the default NTP or the pool.ntp.org), and there's still no internet connection.
Thanks!

What port are you using to connect the RBR750 to the 1200 modem? Port #1 on the CM1200 modem needs to be used for the RBR750.
Power OFF the CM modem for 30 seconds then back on. Then walk thru the setup wizard on the RBR using a wired PC and web browser. This should get you going.
The CM1200 is a modem only, not a router. Just because it has 4 ethernet ports in back doesn't mean its a router. Those are WAN ports.
