CM600 & MOCA Adapter

[wappinne]

How do I wire a CM600 Netgear cable modem to work with Actiontec bonded MOCA adapters?

Is it COAX from wall to adapter; then COAX from adapter to modem, then ethernet from modem to router, and ethernet from router back to adapter?

Or

Is it COAX to splitter, and COAX from splitter to modem and adapter?

   "work" to solve what problem?  What are you trying to connect to
what?  Where is the co-ax cable?  What is "wall"?

   Presumably, you have some kind of co-ax connection to your ISP, which
should go (somehow) to the co-ax port on the CM600.  Other than that, I
have no idea what you want to do.

Sorry; I have xfinity coming in via coax. I have my cm600 modem on one floor. It's connected to an Airport router / wifi access point. I want to use the coax in the house to transmit internet instead of using the wifi. So I am thinking of getting a pair of Actiontec MOCA adapters to do that. I'm just not sure of the wiring. I've seen two configurations: one without a splitter and one with. I'm trying to dicern which to use. Blue lines are coax; red are ethernet.

   "transmit internet" to what?  Neither of your two configurations
makes any sense to me.  Why would there be a closed loop of any kind?
What's a "POE"?  Where does Xfinity appear?

   Ok.  The Xfinity co-ax must go to the CM600 modem, whence Ethernet to
the router.  Any Internet connections must come from the router.  The
router end of such a connection must be an Ethernet connection.  That
could be a standard twisted-pair Ethernet cable, or it could be an
equivalent chain like:

Ethernet --- MoCA_adapter --- co-ax (long) --- MoCA_adapter --- Ethernet

   I'm not a MoCA expert, but, so far as I know, the co-ax which joins a
set of MoCA adapters is strictly a directly-connected tree, using simple
T-adapters (not TV-type splitters) if any co-ax branching is desired.
Typically, it's a simple point-to-point link, with no branching.  See,

for example:

      https://www.actiontec.com/moca/

   Instead of a simple MoCA adapter at the non-router end of the co-ax,
you could attach a MoCA wireless-network extender, which would be
roughly equivalent to:

   --- MoCA_adapter --- Ethernet --- ordinary_wireless-network_extender

   Also, some routers (not from Netgear?) offer a MoCA port along with
the usual LAN Ethernet ports.  That would be equivalent to an external
MoCA adapter connected to a LAN Ethernet port on that router.

   A MoCA vendor might be a better source of information of how to
employ/deploy MoCA.

Do you still need help? I have MoCA adapters set up with my router and they work great. I go from wall to spliiter, then from splitter to modem and adapter separately, then ethernert from router (not modem) to adapter. Hope this helps.

While I've got a different modem / router setup, I am using a pair of Actiontec's ECB6200 Adapter (for a MoCA LAN), and my setup has been in use reliably for 2 years.

I'm providing a jpeg (converted from a PDF I created), which details the full setup, but shows you the initial cabling between Coax wall outlet, Modem (which in this case was an Arris - Comcast - VoIP modem), & my  AirPort Extreme router / switch.

So, just think in terms of substituting your hardware in the cabling setup, & you'll get yours easily completed. (Unless interested, you can ignore a lot of the other connections involved in my MoCA LAN.) ...Let me know of any follow-up questions; I'll be happy to clarify.
