I just added a Roamio to my network which is a mix of wireless and MoCA provided by Actiontec routers. I have two THD DVRs at the same location as the Roamio and they connect using Ethernet which is provided by an Actiontec router. All that works. Now add in the Roamio, connected by Ethernet through the same Actiontec router (it has a 4-port switch built in). The Roamio has two MAC addresses, one for Ethernet, one for MoCA. My router reserves particular IP addresses for each MAC for everything on my network so that everything always gets the same IP address via DHCP.
Connected via Ethernet, via the Actiontec, even though MoCA is not turned on, both the Ethernet IP and the MoCA IP of the Roamio return pings. And the MoCA IP has a latency of 0.004 seconds while the Ethernet connection runs around 0.014 seconds.
Running a Bonjour scan of my network, the Roamio shows up as follows:
DVR-CE6C Zeus _http._tcp. 10.0.1.190:80
DVR-CE6C Zeus _tivo-device._tcp. 10.0.1.190:80
DVR-CE6C Zeus _tivo-mindrpc._tcp. 10.0.1.190:1413
DVR-CE6C Zeus _tivo-remote._tcp. 10.0.1.190:31339
DVR-CE6C Zeus _tivo-videos._tcp. 10.0.1.190:443
DVR-CE6C Zeus _tivo-videostream._tcp. 10.0.1.190:443
STR-CE6C Zeus _tivo-xcode._tcp. 10.0.1.191:49152
I know what a "DVR" is but what's a "STR"? That seems to be the MoCA address presence.
If I attempt to turn on the Roamio's MoCA networking ('Connect using MoCA'), it crashes my Actiontec based MoCA, and the Roamio's MoCA says it cannot find the router.
When I was first setting up the Roamio in another room, turning on MoCA did not cause any problems and I ran the Roamio with just MoCA networking for a while.
To connect the Roamio's coax, I took the coax going to the Actiontec's coax connection, added a 2-way splitter with one going to the Actiontec and the other to the Roamio. So, the Actiontec and Roamio are separated by just a few feet of coax through a splitter. Could it be that they are just too close together?
In Roamio's network settings, what is "Use this DVR to create a MoCA network"? MoCA is peer to peer. None of the devices "creates" a network. Does this perhaps mean, Create an Internet Gateway via MoCA? That is, plug the Roamio Ethernet cable into your cable modem and let MoCA devices connect to the Internet over coax through "this DVR"?
