    It's the "set up properly" part that is the problem.

    You frequently espouse how you have reliable HD streaming over wireless but in reality wi-fi almost always falls flat on its face trying to do this... even moreso in the typical environment in which there is occasional radio interference on the 2.4ghz bands being used, buffering problems due to wi-fi radios throttling speeds down for slower devices, etc, etc, etc, etc, etc.

    The bottom line is that unless someone particularly knows what they are doing (and, like you, has a penchant for buying piles of gear, piles of access points and repeaters, etc) they should steer clear of trying to stream anything better than Youtube quality crap over a wi-fi connection.

    Perhaps I was confused, but his XL4 is connected to an Apple Airport Extreme and is connected to the network wirelessly through the Airport Extreme. The second Mini is connected to a switch, which is then connected to an Airport Extreme (wired) that is connected to the cable modem.

    In order to get from the XL4 to the second Mini, it must go through the Airport Extreme's WiFi connection to the second Airport Extreme, then to the switch, then to the Mini. That is a wireless connection unless I'm missing something in his setup description. The two Airport Extreme units aren't hardwired together, or at least he didn't mention them as being hardwired.

    His first Mini is connected via MoCA. So the XL4 can transfer directly to the second Mini through MoCA and skip the wireless connection.

    WiFi can sustain high data rates (especially 802.11ac), but in most real life situations, interference from competing signals, barriers (walls), etc. make sustained data rates unreliable.

    I think I mis-understood his post, I had thought he indicated that the XL4 was hardwired and after having trouble he hard-wired the 2nd Mini to the same Airport Extreme router. Clearly though I mis-read this.

    And definitely, trying to stream HD video reliably over wi-fi is a bit of a wasted effort.

    The XL4 is hard-wired to a router, but that router is connected to a second router via a wireless bridge. The second router, where the skipping Mini is, is hard-wired to my modem. But since the XL4 is the source for all Mini streaming, any ethernet wired Mini, no matter where it is in my condo, is going across a wireless network.

    So there was a wireless network between the skipping Mini and the XL4. But it worked for almost a month with no skipping. I had a couple of hiccups here and there but nothing that concerned me enough to make an immediate change as this isn't a primary TV. I thought the 10/100 switch was probably a bigger factor.

    Maybe my wireless network was more saturated last night when I first encountered the skipping. Bottom line, I'm aware of the fact that wireless isn't supported and I should have considered that as the primary factor in last night's skipping. It's worked great up to this point but as long as the splitter before my modem isn't going to impact my internet speeds, MoCA seems to be the way to go for me.

    Sorry for the confusion. It can get somewhat complicated trying to determine what is going where if your network isn't simple. I guess the good thing for me is that I have options. I could remove the wireless bridge by putting a MoCA adapter in the room with the modem/router combo and let the XL4 serve as the ethernet source for my wired devices in the living room.

    Unfortunately that is the entire problem with most home Wi-Fi networks. Most are not setup properly. To be setup properly you need multipls APs, APs that are not saturated, plus you need to be using channels that are not congested. The vast majority of home Wi-Fi networks have one or more of those issues which of course can cause reliabilty issues.

    MoCA is usually one of the easiest alternatives with houses wired with coax cable. That should eliminate the issues you are having from wireless. I'm currently running two Minis and two Elites on MoCA. With one Elite using the Ethernet connection for internet access for all the MoCA devices, and my second Elite usng the Ethernet connection to connect my OTA only Premiere to the internet and the other TiVos on MoCA.. I was going to go back to Ethernet only for everything but this setup frees up one of my GigE switches that I needed to use at another location.

    You don't even need to do that.

    Just turn on the MoCA function in the XL4 and have each mini use the integrated MoCA to connect to the XL4.

    The connectivity from the XL4 to the internet is not important, as long as it has one. All local streaming (which is where you will have bandwidth and performance bottlenecks) will be going over coax.

    If someone has coaxial to each room that they have a TiVo in, there's no reason NOT to use MoCA exclusively for the Minis, as long as the XL4 has some kind of internet connectivity.

    MoCA is enabled on the XL4, it's just getting its internet connection from the router serving as a wireless bridge.

    I was thinking I could drop the wireless bridge by using the XL4's ethernet jack as the input for a switch, which would allow me to connect all of the wired devices in my living room to the internet. To do that, I would add a MoCA adapter to the room with the cable modem/router combo, giving my XL4 internet access.

    But I doubt I'll bother unless I run into more problems.

    This stuff gets confusing.
