CM1200 modem not working with R7800 router
I just increased my internet speed to 800 so I got the CM1200 and my R7800 will not get an internet signal from it, the R7800 is the only thing plugged into the CM1200, it still works fine with other modems, made sure firmware is up to date and even hooked them together with the netgear app to insure proper order, the internet works fine out of the modem if say I plug my ps4 directly into it just seems the router and modem are not communicating. Any help would be greatly appreciated.

Try this.
1. disconnect everything from the cm1200 and the router. Even coax. Then power them both off.
2. what 2 minutes.
3. connect coax back to the modem and power it on. wait 2 minutes
4. connect port 1 on cm1200 to wan port on router.
5. power the router on and wait 2 mintues.
see if it can be setup.
Make sure nothing else gets plugged into the cm1200. It has more ports but most ISP's only allow 1 device to be connected to it.
So if you power OFF the CM and R units for 30 seconds and power back ON the CM modem first then R router, does the internet LED turn WHITE on the router?
Have you checked the wan port on the r7800?
Also what are you seeing on the R7800 Basic Tab under the Internet section? Are you seeing "Waiting"?
I'm seeing same on my R7800 connected to ports 2 and 3 on my CM1200. I know Ports 1 and 2 work as I have two different routers connected to these ports before.
What Firmware version is currently loaded on the R7800?
- No, it starts off as a solid orange then once the 2.4 and 5 ghz lights are white it starts flickering with them (still orange)
