I had to change my modem (now a Nighthawk CM1200) this morning and now my Orbi RBR750 Router system won't connect to the internet from the modem. I don't consider myself super knowledgeable in this department, but I also don't think I'm completely inept. That said, I'm sure I'm doing SOMETHING wrong.
My computer is connected to the modem via ethernet and working just fine, but the ethernet connection to my router isn't working. I've tried: using various ethernet cables (thinking one was bad), trying all of the ethernet ports, aggregating the MODEM ethernet port (now back to disabled since THAT didn't work), resetting the Orbi AND the Nighthawk equipment, and have factory reset the Orbi as a last ditch effort. Nothing is working and because the Orbi is outside the 90 day window, they want to charge me $100 to fix it since the Nighthawk is functioning as it should. If anyone has any recommendations here, I'm forever grateful. I've scoured the Netgear community for help/direction without avail as well.
Notice that although the modem has four Ethernet ports, it is the top port that is intended to be used.
After verifying that the modem is working correctly by connecting a computer (desktop, laptop) to the top port, that same Ethernet cable should be unplugged from the laptop and connected to the RBR750 router WAN port. (yellow)
only one device should be connected to the modem at any time.
After connecting, it is a good idea to wait before powering up the RBR750 and first cycle the power on the modem so that it "forgets" about the computer connection and is ready for the router.

Perhaps it would be useful to observe how the router describes the Ethernet connection to the modem.
Connect the computer to one of the router LAN ports, access the management site with a web browser, navigate to the Advanced Tab home page, and click on Show Statistics. How does it describe the status of the WAN port?
