Hello,

I am in the process of updating my LAN.  I am swapping out a Juniper Networks SSG5 firewall with a SonicWall TZ270 firewall.  I am also now using two modems with my ISP (Spectrum).  I took the coax line from the wall and split it in two, one feed goes to the Spectrum Ubee modem and is used to provide two VOiP phone lines.  The second coax cable goes to a Netgear C1100 modem and is used for internet and streaming TV.  I would like to have our primary TV - a Samsung Smart TV, be connected to the internet using wires and not wifi. To do this I have two MOCA 2.5 modems to bring the internet to the coax cable near the TV.  I thought everything was connected and ready to go, but the TV sees the modem but says it has no internet access.  

Here is the current set-up:

Coax Wal ==> Split ==> MoCA Adapter (GoCoax WF-803M) ==> CoAX to UBEE modem for phones

When I log into the MOCA interface it says it has an IP address of 192.168.254.254 and is using 8.8.8.8 for DNS.  The TV is assigned 192.168.254.10 and is using 192.168.254.254 as the gateway.  It does not see the internet.

I am wondering if there is a better way to place the first MOCA adapter.  Rather than place it in front of the cable modem, what if I place it behind either the UBEE or the NetGear C1100 modem?  

Basically, I would like the MOCA adapter to use its own private network 192.168.254.x and for the TV to be the only device on the network.  How can I accomplish this?

Thanks!!
