It seems that the two Ethernet interfaces on the FNE is not bridged to the MoCA interface. Can you manually configure static IP addresses on your computers for now? Then test whether the router is reachable on the link by pinging 192.168.1.1.
Can you go to FNE's web management interface at least by typing the IP address of the FNE into a browser? You can find out FNE's IP address by looking at the main router's connection list.
