    OK....I was not cautious enough last night with my UPNP salvation comment. I woke up this morning to again have lost MRV.

    So this was the final straw. This gave me the motivation to wire two more Cat5 connections and move my two HR24's and H24 to Ethernet.

    It's only been about 6 hours but everything is working flawlessly over ethernet.

    I'll post back tomorrow with the continued results. But I believe the internet deca conflicts with something on my network. I tried to slowly eliminate devices but since the MRV dropouts occur after several hours it's hard to trouble shoot.

    I'm sticking with ethernet if it works! This DECA setup is still beta in my opinion.

    Cheers,
    Scott

    "For grins" I've moved my BB DECA over to the 2Wire to see if there's any change.

    Mine is connected to a switch also.

    Switch - LINKSYS EG008W
    Router - Netgear Rangemax WNDR3700

    There's a couple of data points for the what works. BTW, I chose this router because it's "rated" for streaming HD video. I have notice that some people with issues related to DirecTV2PC tend to be the routers ability to keep up. The load on routers is steadily increasing. That's why I went looking at specs and reviews for streaming HD video when I replaced my router.

    I'm just throwin' that out there as more data to consider. :grin:

    There is a lot to consider in this... and without detailed configuration information everyone is shooting in the dark.

    Perhaps, the Router, F/W version game needs to be played as this would help understand if its a model, F/W version, or configuration that is the problem.

    The multicast traffic is interesting... as would discussions of UPnP traffic.

    Basically - at the end of the day, the router really shouldn't be doing anything - but - obviously it is.

    A full DECA implementation (meaning ONLY the Broadband DECA is connected Ethernet) should have only ONE point of interaction with the router and that is for DHCP (and that is only if you don't use Static addresses).

    What is interesting is the comment that everything BUT playlists work. I'm struggling to follow the various comments/threads and understand exactly what is working in this case. So here's a few questions for the OP:

    1) If you remove the Broadband DECA so the receivers are isolated on DECA only (you'll lose DoD and Direc2PC for this test) and reboot all receivers - what is the stability? Do you stay connected or lose connection?
    2) When you lose connection - can you play items from the stale playlist?
    3) What exactly do you have to do to recover (reboot HR24, reboot HR21, reboot Router)
    4) Is your Broadband DECA connected directly to the router, or is it on a switch and the switch is connected to the router?

    1 MRV It is rock steady if isolated.
    2 No, playlist does not show other receivers when I lose connection.
    3 Rebooting receivers brings MRV back

    Using the unsupported network connection, mentioned above,I'm up and running for about 20 hours, but I have not rebooted the router.
    All networking available and operational.
    MRV,VOD, Directv2PC.
    When I lose MRV all other networking is fine.
    Advanced Netwoks setup shows all OK, Network Connected, Internet Connected.

    I have noticed rebooting router most times results in a lose of MRV,
    requiring a reboot of the receivers.All other networking keeps going.
    Thanks for your interest.

    Later today I will hook the traditional deca config, I do need DECA to reach a bedroom that has no ethernet.

    Ed F.

    P.S. I have changed my router config to only reboot once a week, this could be the reason MRV is running fine, not the unsupported wiring config.

    Your router has a config to reboot itself? Interesting... Mine reboot only when the lightning strikes are close... :lol:

    Ok... well item 1 is interesting. I have a couple theories, but I'll wait until we hear from some others with the problem.

    Is your Broadband DECA connected directly to the router, or is it on a switch and the switch is connected to the router?

    I run an un-supported configuration. I was having the network test fail on the HR24-500 due to a low reading on the DECA test environment. To resolve that, I took the DECA uplink module and the splitter out then connected the 2nd network port of the R22-200 to my switch and use it for the uplink for the DECA cloud. I cannot recommend this, but it works for my environment. This can be seen in my setup links in the signature.

    It's been only about 12 hours since I moved from the switch straight to the 2Wire router, but nothing seems to have changed.
    I'll keep it this way and see if anything changes.

    Copying the questions down here to keep em fresh and to add #5:

    1) If you remove the Broadband DECA so the receivers are isolated on DECA only (you'll lose DoD and Direc2PC for this test) and reboot all receivers - what is the stability? Do you stay connected or lose connection?
    2) When you lose connection - can you play items from the stale playlist?
    3) What exactly do you have to do to recover (reboot HR24, reboot HR21, reboot Router)
    4) Is your Broadband DECA connected directly to the router, or is it on a switch and the switch is connected to the router?
    5) Does your switch or router (whatever the Broadband DECA is connected to) have port and duplex speeds? Are they set to Auto/Auto or hard coded to something?

    how is this different than setting the IPs up at the router by MAC address? (which is how I have it now)

    What happens when you set them at the router by MAC address is the client still uses DHCP packets to get and request. The only difference is the router, instead of assigning next available, always assigns the reserved address.

    So this means, if there is a problem with the DHCP assignment either because of the Broadband DECA or some bug in either the router or DirecTV - it will be exposed whether you use address reservation or not.

    When you disconnect from the Broadband DECA, DirecTV uses assigned addresses that act like fixed ones so DHCP is not in use. If you assign an address at the receiver, DHCP is not in use. So, the thought was that if it works without the router, perhaps its a DHCP issue since that is the only role the router should be playing in a closed DECA MRV environment.

    However, if the statement is true that DoD and Direc2PC still work when MRV fails, then this can NOT be a problem and it doesn't matter how you assign the addresses.

    Chris, here you go:

    1) When BB DECA is removed, system has been stable. My last test showed the system stable for over 3 days whereas with the BB DECA I'm lucky to make it 24hrs. I would be happy to remove the BB DECA and wait it out to see if I ever have any problems?

    2) No - I get weird errors (packet loss) and/or we get lockups, or the playlist just goes away from the remote DVR and when chosing the yellow button, there is no option for shared playlist settings

    3) Recover = reboot all DTV boxes. everything works flawlessly for a period of time

    4) currently, the BB DECA is hooked straight into my router - a NETGEAR WGR614v9 with F/W 1.1.2.30NA. I am planning on adding a switch, just don't have it yet. Ordered from NewEgg..just waiting for it to arrive.

    Dont use D2PC, and haven't checked VOD when this issue crops up. I will test VOD/DOD the next time we lose the playlist to see what might be happening.

    It sounds like you are pretty familiar with things... rather than doing that or pulling the BB DECA out... it would be more useful if the next time the problem happens you ping all 3 of your receivers and post the results. Use the following:

    ping <ip address> -t

    The -t will let it run continuously. Post if it fails right away, or if not, let it run for a minute or so and watch if you get sporadic times or No replies.

    sure, will do. I think I ping'd them once before, but didn't use the -t switch. I'll make sure and do that to see what is going on.

    FYI, my router has no way to change the DHCP lease renewal setting. I'm starting to wonder if the DHCP renewal is the issue...

    These tests will tell us... if its DHCP renewal the box won't ping at all as it will drop its IP address. It would be much more consistent after reboots though... exactly every 8 hours, or 24 hours type behavior. But its definitely worth exploring.

    could i just force a reboot (pull the plug) to see what might happen?

    When MRV fails pings to both receivers are all fine
    no packets lost
    average 4ms

    Thanks

    How similar to the OP issue is yours? Failed MRV doesn't necessarily mean the issue is the exact same. I'm just curious if both of you see the exact same failure.

    If pings are successful, if other traffic is successful, we know a few things:

    1) It can't be a DHCP issue (you'd have no IP to ping)
    2) It can't be a physical layer issue (other traffic works)
    3) It can't be a network issue within DirecTV receivers (or no traffic would work)

    Whatever the trigger is... whatever makes the problem happen... if the description and testing is correct, the problem lies in the MRV code of the DirecTV box, and how it deals with a failed or reset connection. It appears that either a bad packet, broadcast storm, or some other "trigger" occurs, and that locks up the MRV application on the box.

    I'm curious - whether a reboot of ONLY the server works - or if you have to reboot everything. IF everything described is true, DirecTV needs to address it. We can keep finding the "trigger" (such as a bad DECA, or wiring, or a router) - but removing that trigger will only fix it for that person... the next persons trigger may be something different.

    FYI, removing the BB DECA seems to work for me - but we obviously want DoD/VoD so I'm trying another solution which is to add a switch in between the DECA cloud and the router. Hopefully this will isolate the DECA traffic away from my other network traffic and take the burden off of my router somewhat. I have no way to change the DHCP lease time since my router (NetGear WGR614v9) has no setting for this, and i"m thinking that might have something to do with my issue - so I'm hoping this switch might save the day...
