    I have seen conflicting answers on this so I will start a new thread about it.

    If you put in an Ethernet switch (or just swap the cable) on the DECA adapter will that allow you to connect a non-DTV device and access your LAN/Internet connection?

    Thanks.

    I've not tried this, but if you are using DECA to transport something other than DIRECTV traffic you may find that things are not working as well as you'd like.

    My recommendation would be to NOT do this under any circumstance.

    Maybe this is oversimplfying it, but isn't DECA just a method of diplexing ethernet into the coax? With that logic, the OP's idea should work fine. Unless the DECA adapter is not providing 100 BaseT speed.

    DECA is limited to 16 devices .. period. Adding non DIRECTV devices will certainly eat up that total.

    Also, DECA is optimized for video delivery using DIRECTV's protocols. A third party device could introduce anomalies in that setup that somehow de-optimize the system.

    I'm not saying it won't work .. I'm saying that I'd recommend not doing it because the results may not be what you expect.

    DECA networking is the supported network from DirecTV, so I'd guess the real question should be: why deviate from what DirecTV supports with some modified setup?
    "If" there would be a problem introduce, who is the one that's going to resolve it?

    The answer to the why question would be adding a LAN connection to a location that does not have Ethernet cabling to it.

    [shhh don't tell anybody]
    It would work, but if/when there is a problem, remember to reconfigure back to the supported setup first, to eliminate any issue this might cause.

    In my case:

    I have a wireless hub (connected as a repeater-bridge) that feeds internet to my PS3 as well as the HR20. I do not have CAT5 to that location but do have RG6.

    /IF/ I can install a DECA on the RG6, connect a switch to that device, and then provide ethernet to my HR20 as well as my PS3... I would be happy.

    If 16 DECA units are addressable on layer 2, it shouldn't matter how many layer 3 addresses are supported by those... correct?

    I don't understand the argument against this.. what could you possibly introduce that would cause instability.. Sure you could saturate 100Mb, but that's incredibly unlikely...

    Am I missing something?

    I doubt you're missing anything.
    What we [or myself] may do, may [will] work for us, but understand from DirecTV's view point, we're modifying their network and as such we shouldn't expect them to support us any longer, or at least until we reconfigure it back to their standards.

    I am hoping to do something similar with a Blu-ray player. My DECA install is this morning. After this weekend I can give some feedback as to how it works to have a switch and another device in the setup.

    Please do so, because I'd be another one that would appreciate it. I've got an AppleTV that I was planning to connect to the network via a switch on my DECA, and in another room, I've got a new Samsung LED LCD that has an Ethernet input for media capabilities and I was planning to do the same thing in that room as well.

    I hear the argument about possible problems from introducing another type of data over the network since DECA is optimized for video data, but aren't the expanded D* On Demand movies just basically data delivered to your HR2X via high speed internet (in the same manner that an AppleTV works)?

    I'd kind of say: if you're knowledgeable enough to ask the question, you would have the [correct] answer too. ;)

    This comes up all the time with U-verse. It's very common for people to have devices they want networked near the TV (xbox, blu ray, HTPC, etc), and going wired is always better than wireless. People eventually figured out that you can attach something to the ethernet port of the U-verse STB and it gets bridged onto their HPNA signal. Of course, this is all totally unsupported by AT&T, but it works just fine. I don't expect DECA will be any different. Of course, theory is no substitute for real experiments and experience. :)

    My DECA install is complete. I will add in the switch [actually its an old router, but I will have it functioning as a switch] and Blu-ray player tonight and play around with MRV and Netflix over the weekend and report back how things are working.

    So could I connect my Slingbox to the other port on the HR21? Let it go DECA to the router??

    You could use the DECA + PI, like for the broadband connection.

    so they would have 2 DECA modules than one for the HR21 and the Slingbox
