Interoperability issues with RBR50 and CM1100

[linder5]

I have an Orbi RBR50 Mesh WiFi Router and a new CM1100 Cable Modem.

Frequently, the Orbi goes offline (displays pink) and the CM1100 Modem either reboots or goes offline.  And, the net is, the RBR50 stays offline until both the router and the modem are rebooted.  And often, it takes several reboots before the Orbi Router will stay online.  Not sure what the problem is, but my network is all Netgear and this issue is super challenging, consider television, computers, and mobile devices are on the network.

Anybody else have an issue or experience something similar?  Recommendations?

Thanks...

Can you name the Internet Service Provider?

Spectrum is the cable service provider.

What Firmware version is currently loaded?

Swap LAN cables between the RBR and CM modem. 

Have the ISP check the signal and line quality UP to the modem. 
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 

Any Wifi Neighbors near by? If so, how many?

I love my CM1100 connected with my Orbi systems.

firmware on RBR50 is 2.5.1.8 (which accordingly is the most current available)

firmware on the CM1100 is 2.01.02 (which is controlled by Spectrum)

I've changed out the cables as well

ISP line quality is excellent -- Spectrum was here several months ago to adjust signal strength in the entire house

A few wifi neighbors, maybe 2 that are visible to me.

After getting it operational yesterday, I had about 12 hours of uninterrupted service before it "bellied up" again this morning and everything had to be rebooted multiple times.

v16 would be the most current.

Be sure LAG is disabled on the modem. 

You might try a factory reset on the modem and RBR and setup from scratch.

What is interesting is that as long as only the cable modem and the router are booted up, it comes up.  I have a couple of Netgear GS208 switches on the network -- if they are operational, the router won't connect on the network... If they are off prior, the Orbi will boot up properly.  Interesting dynamic, so not sure what or why this happens, but seems like it this is one way around my specific challenge.

Can you make a rough diagram of how all this is connected?

i.e. coax to->CM1100-> ethernet to-> Orbi WAN (yellow) port, then where are the GS208 switches?

[linder5]

Coax to->CM1100-> ethernet to-> Orbi WAN (yellow) port -> GS208 -> GS208

That would be the best configuration.
