    Yep, I knew that. :)

    But before the PI, after the PI, on SWM output #1 or SWM output #2, before the splitter, after the splitter, or any of the above?

    That was the question. :)

    And what I meant with the IP addressing was that a DVR on one SWM with the dongles should be able to MRV with a hardwired DVR on the other SWM? (since they'd both be on the same network).

    I would be careful of putting dongles between the PI & SWM, since we don't know what voltage they're rated for [yet].
    DHCP should be handled by the router.

    Should be able to go anywhere...only thing that might be a bad idea is directly between the PI and the SWM. Even that might be okay.
    Then why didn't you ask that... :D
    Yep, same LAN...dongles are just bridges.

    So seems like I'll put one dongle at each receiver and the network dongle right after the PI before the splitter.

    Interested in how we all think the IP addressing works.

    I guess we first get the network dongle in place so that there's a bridge from COAX to Ethernet.

    Then as each receiver boots up it requests an IP address (thru DHCP), out through the receiver Ethernet port, through the receiver dongle, through the network dongle, onto the network, and to the DHCP server?

    Don't forget to reboot your router too. :lol:

    Network dongle should be able to go anywhere [short of PI to SWM], so before or after the splitter. "Unless" the 850 MHz is terminated in the dongle [not simply tapped], and not passed through it.

    Haven't re-booted that D-Link DGL-4100 Gigabit router in a year or more :)

    Interesting ... so a receiver on SWM output port #2 can get out to the network on SWM output port #1. That would mean the SWM firmware is very MOCA aware? I wonder how that works ...

    "Or" the simpler thing is SWM 1 & 2 are merely outputs of an internal 2-way splitter, with one leg power passing.

    So they'd be inputs as well in this example. A receiver with a dongle on SWM port-2 would need to go up thru the SWM and down port-1 to get out to the network through the dongle after the PI. And visa-versa for the network communicating with the receiver. Interesting ...

    Did everyone forget my "prophetic" diagrams already?

    You can see most of the answers in them :) :)

    No, can't link two or more SWM nets together via coax. Very bad.
    Yes, the HR2x and H21+ are still limited to their 100Mbs ports.
    This will look exactly like a wired network to the HR2x and H21+. It is using their normal ethernet ports. Including DHCP, tcp/ip, bandwidth, etc.
    You shouldn't have to reboot any routers. Should look like adding any new network device to the network.
    You will need a coax line somewhere near a network jack. (Or the traditional geek approach of a long cable on the floor.) :)

    This one will really bake your noodle: The MoCA network can be completely envisioned without any SWM at all. The only thing the "SWM does" is tell the receivers to use SWM communications, it doesn't really affect the MoCA network in any way.

    Cheers,
    Tom

    Oh, and the one dongle connecting the coax and wired nets together has its own PI. I don't know what that will look like.

    Just like any other splitter in the MoCA network. :)

    So if the dongled receivers :) are still getting their IP address from the DHCP server, and they're "on the network", why wouldn't they be able to communicate with the receivers that are on the other SWM that are hardwired to the same network?

    The operative word is "shouldn't" have to reboot the router, but everyone "should know" that you might have to to reset the IP addresses and anything else that might be needed.

    My noodle was baked a long time ago.
    While MoCA can work on any "splitter" system, a Non SWM DirecTV system isn't one of those.

    Depending on which version of MoCA, there is a limited number of devices.
    "Seems like" if you're not excessing the max number, that you could bridge MoCA across more than one SWM system, [even through a RF/coax link with diplexers]. If you exceeded the max number, then you'd need to bridge with Cat5 and let each SWM run their own MoCA network.

    Perhaps even a triplexer, so you could bridge MoCA across more than one SWM system by passing just that middle band, and leaving the low and high ends isolated.

    This fourth dongle that will marry the coax network to our existing home network, can it be inline like the SWM PI, meaning that you could connect a receiver/splitter to it? If so, we wouldn't need any additional splitters.

    They will still be able to see all of your other receivers. They "new' network is like a subnetwork inside of your existing network.

    It will have to be done via dongles.

    Man, I go away for one day and I see 7 pages added to this thread. Guess it is time to go to the UserCP and change the default settings. :lol:

    This really should be pretty easy to do, even easier than hooking up a SWM without getting "smoke". :)
