    So, I've now got wireshark.
    "The process that creates the hang in the router," is downloading a CE, so it's going to be a few days.

    No other way to duplicate it, like a reboot?

    VOS,
    Turn of the firewall stuff on the router. The fact that a router is installed, the router is considered to be a hardware firewall already. My thought of a router firewall is for setting up restrictions for multiple users in the home network that may need some port blocking.

    ...and with a potential Windows firewall, Norton (or other) firewall, and router hardware firewall all potentially there to be activated or deactivated, not to mention conflicted....the plot can indeed thicken pretty quickly.

    In my case, I turn off the Windows firewall all the time, and the Norton from time to time, especially during certain testing - to make sure it does not interfere with results.

    I'm sure I'll need to disable my CA firewall for this "sampling". Windows firewall is replaced with the CA.
    I wouldn't have Norton on any of my systems since XP SP2 came out. :nono:

    I can't argue with the logic there...Norton is not my friend....:D

    Step #1: connect a hub to the output of the HR21's second port & connect this PC to the hub [moved from a switch].
    Step#2: close all apps on PC and launch Wireshark.
    Step #3: reboot HR21 and download CE.
    During the download, the hub showed the HR21 as being off-line.
    After download finished and the HR21 came back to live TV, stopped Wireshark and logged back into the chatroom. No resets of router/PC.

    Round #2:
    Removed hub, so HR21's second port was straight to my router. PC back on the switch to another port on the router.
    Joined chatroom & started downloading on the HR21.
    Opened up a few tabs on the forum. This fifth tab wasn't connecting.
    Launched wireshark, and about this time I was booted out of the chatroom.
    Wireshark showed the PC asking who has my router's IP 45 times. Then my router asks who has my PC IP once. After which the PC asks 67 times more, who has my router's IP and I stopped Wireshark.
    Tried to have my PC "repair" its network connection. The first few times it came back with it couldn't and it couldn't find my modem under details. At some point I think my options had changed and I picked another to get an IP address. This time it worked and came back with the same IP for the PC that it had before.
    Last night I moved the DECA off my H21, connected the IP to it and ran another coax off my 4-way. The H21 is now running off the HR21's second port [as before the DECAs came].
    Logged into chat, opened all my forum tabs and downloaded the CE to my HR21 for the third time. Everything went fine.

    The router is a 5 year old Netgear RP614 and I'm starting to come to the conclusion it's the problem, since it doesn't respond. Resetting it is the fastest way to "clear" the problem.
    When it has: 1 port to my switch/PC, 1 port to DVR, 1 port to DVR, & 1 port to DVR with receiver daisychained, it doesn't have any problems.
    Changing over to DECAs, 1 port to switch/PC and the other port to the HR21's second port, has four IPs being router/fed off this port.
    Resetting/rebooting the HR21 doesn't cause any problems.
    Resetting and downloading does. The only differance seems to be the network jack is not powered for a longer time. Somewhere between the 10% to 60+% mark in the download, the router "hangs" and stops responding to the PC requests, "but" if the PC is also on this port [with a hub], it doesn't hang.
    This has me :confused:
    Basically it seems:
    If there isn't anything [of the 4 IPs] responding off this port for more than the time to reset a receiver, the router becomes unresponsive.
    If each receiver has its own port, I can have all downloading [at the same time] without the problem.
    If I keep the DECA cloud active, I don't have a problem.
    If I keep one active IP [hub] and have the other 4 IPs drop offline, I don't have a problem.

    Anybody want to try to explain this and maybe some settings to try/change in this POS router? :lol:

    I wouldn't even know where to start..but you may have answered your own question in this last statement. :D

    My weekend project was to replace my NIC card in my desktop with a 1Gigabit NetGear unit. That actually went pretty smoothly.

    I wanted to finish this last piece of "pre-WIN7" upgrading to the PC.

    It also allowed me to do some more testing with all the DECA-connected HD devices here...especially, I was curious to see how TVersity now would work everywhere.

    There was a clear and definitive improvement in performance. Both photos and video loaded and played back much quicker (and I have tons of photos alone in my folders).

    With this last CE...all system tasks continue to pass. DECA still going strong here.

    All my PCs have 1Gigabit NICs, routed through a 1Gigabit switch, then drop down to the 100Megabit network through my router.
    The DECA cloud has shown no change from the 100Megabit network, but [DUH] the receivers are limited to 100Megabit NICs.
    [BTW] this router is going to need to be around for a while, as there are much higher things "earmarked" for my cash these days.

    Everything here (PCs/laptops) until about Spring had 10/100 network cards - and of course, all DirecTV devices do too.

    Since then, my desktop is the last to now be 1Gigabit...2 laptops and the router itself all support 1 gigabit, and downshift to 10/100 as required.

    The inter-PC transfers are much faster, needless to say....but since the desktop PC holds the MediaShare files...and now with the 1 gigabit NIC card, transfers to and from the router are obviously faster, providing the ability of the DirecTV devices to have optimum delivery, even in a 10/100 world.

    Your debugging techniques are very valid steps VOS. Good work!

    I will take a look at your capture Monday morning.
