    Still not getting it. As far as the router is concerned it's all the same. For a normal networking setup you are going to use the same subnet for all devices on your network so they can communicate with each other, and you are also going to have your router assign IP addresses via DHCP on that subnet, or you are manually specifying static IP addresses on that subnet.
    Let's say in the minimal case you only have an XL4 and a Mini using MoCA and the XL4 connects to your router. You are still bridging MoCA to ethernet in order for the XL4 and Mini to be able to connect to the internet, so even in simplest case you are always bridging MoCA to wired ethernet.

    Yes you're bridged but the way I understand it, when you're streaming your video from the XL4 to the Mini and you're using MoCA, it sends the signal directly through the coax from XL4 to mini, bypassing your router attached to the ethernet connection of your XL4. If you were using ethernet on your mini, the only way it could communicate with your XL4 would be through your ethernet LAN, which includes your router, thus possibly bogging it down with the extra bandwidth of the video stream.

    I "think" when you bridge it and install a mini via MoCA that you're correct that it then assigns an IP, etc. from the router, but once it's setup and the 2 tivo devices are communicating with each other via MoCA, then as I said the stream goes direct through coax to the mini, not needing the router & ethernet at all unless it needs to go out to the internet. At that point it goes MoCA to XL4 which "bridges it" over to it's ethernet port and out to the router, modem, WAN, etc.

    Experts, do I have that right, or am I confused on how all this works as well? :confused:

    If the traffic is between the XL4 and the Mini over coax using MoCA then the router and ethernet switches should NEVER see the traffic. Unicast traffic will only travel between two devices on the same physical subnet, it should never be "broadcast" to the entire connected network. Not ever.

    It' no different if you have the Mini and Xl4 connected through a switch, and one port of that switch is connected to the router. The traffic between the Mini and the XL4 will stay in that switch and won't go through the router unless it is accessing the internet, or other devices on the network where the path to access them is through the router.

    Just minor nit picking...

    Unicast traffic will only be seen on the sender's port and the port required to reach the receiver, this is not a subnet, a subnet is referring to an IP subnet defined by a network mask.

    Broadcast traffic will be transmitted/sent on ALL ports of the switch
    Multicast traffic IF your switch is multicast aware and configured will be transmitted only on the port(s) participating in the multicast traffic, otherwise it will be broadcast to all ports.

    I also see the same gripes about WiFi and why TiVo doesn't support WiFi for streaming even though WiFi has enough available bandwidth to support streaming. I believe the simple reason is, in residence without careful planing there can be too many sources of interference and weak signals that can degrade the WiFi signal to a point were it cannot reliably support streaming and TiVo simply doesn't have the man power, ability, or desire to troublshoot somebody's wireless network.

    TL, you are correct of course. I tend to use subnet and "segment" interchangeably these days, at least when talking about this uncomplicated stuff.

    I've had my 2nd Mini running for about 10 days now off an Ethernet switch that's bridged off my P4. It's working fine, except that when I first go to use it, it's unresponsive to remote control commands for about the first 25-35 seconds. That may not sound like long, but it seems like an eternity when you're pushing remote buttons with nothing happening. My other Mini connected by MoCA is responsive immediately.

    I'm wondering if its taking awhile for the switch to realize that the Mini has "woken up". I think I'm going to try it with MoCA.

    Try a different switch. When I had my two Minis on Dlink Gigabit switches, they were responsive right away, just like from MoCA and wireless bridges.

    I actually happen to be using a D-link Gigabit switch. I don't have any other switches. It's a newer switch that supposedly has some energy saving features, so I do wonder if there's a setting I could change on the switch to disable energy saver mode. I suspect that could be causing the delayed responsiveness.

    In the end it's going to be pretty much academic to me if MoCA works better.

    I had a similar problem where the mini worked with my Netgear switch during set up and then stopped working. Turned out I had to replace the ethernet cable that shipped with the mini to a different cable.

    I have had issues on my Gigabit lan with bad cables in the past.. Strange that is worked at first and then failed. The only thing I can think of is the mini starts up as 10 Mb, and then switches to 100Mb after the first connection/update and the cable failed at those speeds with the cable shipped.

    It is highly unlikely the switch can be changed in that regard unless it is a fully managed switch. What is the switch model #?

    I think it's a DGS-1005G

    That's an unmanaged switch, meaning, you can't set anything on it.

    My switches are the newer Dlink 5 and 8 port switches. That same model number has applied to several different designs.

    I've had two Ethernet cables fail in the last couple of days. I don't understand what fails in the cable? The cables were not touched, no kinks, still look like new, but they fail?

    You'd have to be more specific. The most likely way that a cable "fails" is if the crimped on connector at the end (RJ45) gets pulled enough that there is a gap between the wire end and the metal tooth in the RJ45.

    Other reasons for cable failure include doing things like bending, crimping or tightly rolling a cable.

    I had a bunch of Cat6 cables fail from Monoprice. So I made sure not to buy any more and went back to buying Cat5e cables from them. Which is all I needed for gigabit anyway. I had purchased a dozen or so a while back and around nine of them failed on me over several weeks.

    I move my connections around several times a month. So the Monoprice Cat6 cables are very rigid and the connection was getting messed up creating an open on some of the wires at the connector since they were so rigid. I've never had that issue with the thousands of cat6 cables we've used at work over the years. But those are also alot more expensive than the Monoprice ones.

    I should have never stopped using the Monoprice Cat5e cables anyway. I'm using over eighty of them between my place and my GFs place and they have always worked great over the years.

    I also use monoprice cables, and have good luck with them. Thanks for the tip about there cat6 cables.
