    I don't know how much more secure POE filters make a network, but they do prevent signal interference between any adjacent homes sharing the same cable tap that also use moca. RCN installs them as a standard part of their Tivo installations for this reason.

    Bright House Networks installs them for their WHDVR as well.

    Are POE filters unidirectional, the one I have doesn't indicate which way it should be installed.

    POE should be one directional at point of entry

    Physically though, is there a difference in the direction the filter is installed. There is no arrow indicating the direction of signal. I can only assume that since it isn't marked that it doesn't matter.

    Depending on exactly where the POE is filter is installed, on the first splitter or on a cable leading to the first splitter, the direction may be different.

    Also, Cox recommends using one on any DOCSIS device on the network, (cable model and tuning adapters) Depending on if the filter is installed on the device itself or on the splitter the direction may be reversed.

    good question- mine has a tape band on one end but i couldn't figure if that was the end that blocked or passed- lol. So i hooked it on how it was easiest at the splitter and went with it.

    from reading the writing on them it looks like just a filter that blocks the frequencies that moca uses so i figured such a device probably would be omnidirectional. But again- I'm just guessing.

    it is good to hear that the cable companies installs the filters- sounds like it's wise to have then.

    How does it compare against hardwired ethernet speeds?

    You are limited by the Ethernet limitation of the equation but i believe it maxes out at 270Mbps

    Wait, I'm confused by this. I though MoCA uses coax only?

    If you are using Moca to Moca devices yes, but take the standard premiere and the XL they dont support moca,so you are converting the network on the coax, back to Ethernet for the device

    The moca adapter connects to the Tivo by way of the ethernet port for all Tivos except the Elite/XL4, which has it built-in. So those boxes are limited to the speed of the Tivo's ethernet port, which is technically 100 mbps for the Premiere, and lower for any older hardware.

    Actually, I believe all Premieres are limited to 100Mbps. The XL4's chipset (BCM7413) only has the capability of 2 100Mbps ports on it (I sincerely doubt they are bonding two of them for 200Mbps throughput), which means that even when connecting to MoCA or Gigabit Ethernet there is only the ability to throughput 100Mbps to the Tivo.

    The instruction posed earlier mention using Rev A, C or D, but there have been issues with A and we should use later revisions.

    Looking online I'm finding revisions F-I. Can anybody confirm that these even later revisions can also be easily converted (turning off wifi, ect.) to a MoCA router? Or should we look for a Rev C/D?

    Thanks,
    Haplo

    I have one that is an A and has no issues

    They must be doing something because when I measured the speed on my first Elite I could hit peak throughput speeds of 130Mb/s from the gigabit Ethernet port. But this was also when having the box deal with a bunch of streams. I have not tested anything with the new software. With the old software last year it would let you initiate too many streams and the box would reboot.

    I have used a Rev D and am currently using a Rev F, both without issues.

    The older Actiontecs are only MoCA 1.0. The newer ones are MoCA 1.1.

    I think Rev. F was the first one to support MoCA 1.1.

    And since MoCA 2.0 chips were just released hopefully Actiontec has a MoCA 2.0 router soon. Especially since any new TiVos next year should have MoCA 2.0 capability as well.

    I don't know what to tell you other than, everyone else seems to get around the 80-90 Mbps realistic max of a 100Mbps link. The 130Mpbs may be an aberration of the measurement method (transfer speeds are hard to measure realistically). Even on that one, you said that you measured 95Mbps average. That is a very high efficiency for a 100Mbps link, but not unheard of however.

    Yes, peaks are not an average, but it is impossible for a 100Mb/s connection to get 130Mb/s peaks. If I measure speed from a 100BT connection I will not see any peak speeds like that.
    The bandwidth monitor program measures the throughput average as well as the peaks.

    I'll need to set it up again one day to see what I get with the Spring software. But I don't have as many TiVos now so I can't push it to it's limit any more.
