Modem not receiving signal from MoCA adapter

MaroonR

New Around Here
Hello,
I recently bought a new router from Netgear, the WNDR3400, because my previous router was dying and my range within my home had deteriorated. Before I replaced it, I was using MoCA adapters to hardwire my desktop to my network (I've tried using a wireless card to resolve the issue but my computer will just crash repeatedly if I use it). Now that I've replaced my router, my MoCA adapters are no longer working.
From what I've seen, the modem that it is connected to doesn't receive any signal from the MoCA device. When the modem receives an internet connection, it reports cable activity by lighting up several different LED's. When I connect the MoCA device as it says to in the manual, the internet LED simply flashes, indicating that it is waiting on an internet connection. I've tested all the cables, and they all work, so I'm assuming its a problem with the internal splitters within the MoCA. I don't have a lot of experience with coaxial, so if there's any additional information needed, I'll be happy to offer what I can. I can say that (just from being in the room) the wall-coaxial cable has been split once already to provide service to a TV not more than 10 feet away, but I feel like that shouldn't matter since they worked before.
I've noticed that the MoCA does not send back out a MoCA traffic signal when I connect the other device to another coax connection, however, when I connected it to the coax connection that supports the TV that's across the room, both devices registered MoCA traffic. I don't feel like I should have to make any major changes to make this work. Any ideas?
 
Did the MoCA gear work with the prior router?
If so, there shouldn't be any difference, as the MoCA devices are layer 2 bridges and aren't TCP/IP-aware (need no IP addresses, etc).

When you plug the MoCA device into the Router's LAN ethernet port, you should get a "link light" indication. That LED may blink if there's data traffic flowing.

There is an IP address used to administer the MoCA device. Often, this is obtained by a DHCP request made to the router. In your router's screens, there should be a display of devices with a DHCP address granted, and among those should be the MoCA device.
