  • SNBForums Code of Conduct

    SNBForums is a community for everyone, no matter what their level of experience.

    Please be tolerant and patient of others, especially newcomers. We are all here to share and learn!

    The rules are simple: Be patient, be nice, be helpful or be gone!

    Avoiding IP Address Conflicts and Data Collisions

    MoCA shares the physical medium using TDMA. Each MoCA device is assigned a timeslot in which it can talk, and all the other devices listen. There are no collisions, unlike Wi-Fi or classic Ethernet.

    Networking over Home Coax. Infra.

    HomePlug runs over powerlines, which are a noisy and uncontrolled medium. The comparative charts tell us how well the HomePlug handles actual conditions in a particular house. MoCA runs over coaxial cables, which are a shielded medium with very little noise. The MoCA adapters should always...

    Regarding HomePlug Networking

    Dave, your bandwidth needs are relatively high because you are streaming HD video. Wired Ethernet would give you a lot more headroom to work with. HomePlug is a nice option when it is inconvenient to run Ethernet wiring. Because of the bus topology, though, all HomePlug units will share the...

    Advice setting up my MoCA Network

    When your tech swapped out the four-way spitter for a three-way, and changed the connection from a 7 dB loss to a 3.5 dB loss, that only got you an extra 3.5 dB. You should've gone from 20 dB loss to 16.5 dB loss. Since you went from 20 dB to 3 dB, that means that there was some other problem...

    MOCA gigabit?

    There are products right now for running HomePlug over twisted pair, coax, or powerline. However, HomePlug hasn't yet succeeded in breaking out of its fortress market of powerlines. Why would G.hn be able to succeed where HomePlug has failed? They're starting out from even farther behind than...

    MOCA gigabit?

    Interestingly, Anandtech sent someone to CES 2014 and decided it was "the end of the road for G.hn," because they haven't been able to get any customers: http://www.anandtech.com/show/7704/powerline-networking-end-of-the-road-for-ghn One year later, Tim goes to CES 2015 and finds that G.hn has...

    Networking over Home Power Infra.

    There is something appealing about a single standard that can run on all three mediums: coax, powerline, and phoneline. However, the merger of HomePNA with HomeGrid is basically a merger of two losers. They've lost to the competition on all three fronts: HomePNA lost to MoCA in coax...

    Powerline Homeplug AV2 Utility?

    This Newegg user review says that the ZyXEL and TP-Link utilities both work on the D-Link units: http://www.newegg.com/Product/SingleProductReview.aspx?ReviewID=4295340

    newbie needing help with a moca setup (ota signals)

    UHF television tops out at channel 51 in the United States, which goes up to 698 MHz. Channels 52-83 have been reallocated for other purposes. MoCA can operate as low as 500 MHz, in order to offer the option of coexisting with satellite TV. However, the MoCA adapters that are designed to...

    Questions about TP-Link AV500/300Mbps Powerline adaptor

    I feel that you are constraining your options too much. You're thinking that the Wi-Fi must be integrated with the HomePlug on a single unit. That really doesn't have to be the case. You could optimize the two variables separately. Buy the best HomePlug unit you can, even if it has no...

    Powerline / Homeplug via gigabit switch ?

    Is there any particular reason that you do not want to move your DSL modem to the first floor? Then you could go DSL-router-HomePlug on the first floor, and then HomePlug-desktop in the basement. Your desktop would then remain behind the router. If you can't do that, you could get a second...

    Powerline AV2 1800 adapter

    Electrician made changes, and powerline suddenly drops to near useless

    GFCI receptacles are sometimes installed to feed all downstream outlets. If the GFCI is feeding the rest of the circuit, then a plug-in GFCI tester on a downstream receptacle will be able to trip the GFCI in the kitchen. That having been said, the problem really could be anywhere. As with...

    Advice on how to optimize a powerline network

    How much money are you willing to spend? Devolo makes a HomePlug-over-phoneline device, the dLAN 500 AVpro UNI, which has gigabit ports. Thus, it is not gated by the Ethernet connection and will give you access to the full bandwidth that the phone line will support. The problem is that it...

    Advice on how to optimize a powerline network

    Did you leave the existing phone lines in place? Are they in use? If the answers are "Yes" and "No", then you could repurpose your phone lines to carry the broadband inside your house. There are HomePlug adapters that will run over "dead" (de-energized) phone lines. Because there is no...

    I use MoCA. Should I consider powerline?

    To quote from the design manual, Homeplug AV and IEEE 1901: A Handbook for PLC Designers and Users (p. 313): Send two signals, but receive up to four signals. But neutral is tied to ground at the service panel! The frame of the flat-screen television is tied to the ground pin on the plug...

    HomePlug AV2 Head-To-Head

    Yes, it would reduce speeds, but it would not result in asymmetric speeds. Pure attenuation (without any noise) should have the same effect on signal strength in both directions. Noise is different, because it matters where that noise is introduced onto the circuit. Noise introduced near...

    AFCI and powerline updates?

    HomePlug AV has no problem crossing phases. Nor does it need 240 V appliances to be turned on. (Which wouldn't really achieve anything except to add noise to the circuit.) I am making this very post through a cross-phase HomePlug AV network, with all 240 V breakers in the OFF position...

    AFCI and powerline updates?

    That's correct. In fact, Homeplug AV relies on the capacitive coupling in parallel wire runs to transfer signals from one phase to another. However, you do not want the HomePlug signal to get capacitively coupled to the AFCI. You want it to get coupled to the other phase. The AFCI is...

    Powerline networking -- surge kill devices?

    HomePlug adapters have MOV varistors in them -- same thing that's in the surge strips. Tim's reviews have photos of HomePlug circuit boards on them. The MOVs are the little blue things between power and ground. The varistors can only soak up a certain amount of energy before dying. So the...
