Specifically are the CM2000 and CM1000 Netgear modems compatible with the older Netgear AC1200 model R6220 router?

While many questions about routers are generic and could be answered anywhere, some things need specialist knowledge.

You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:

Cable Modems & Routers

I will ask the Netgear moderator to move your message.

In the meantime you could visit the support pages:

Support | NETGEAR

Feed in your model number and check the documentation for your hardware. Look at the label on the device for the model number.

You may have done this already. I can't tell from your message.

I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.

There are some reviews on 3rd party websites that claim the latest Docsis 3.1 Netgear modems are not compatible with older Netgear routers.

Not much information in there for anyone to go on.
