    I have 2 Tivo boxes: a Premier XL 4 and a series 2 both connected to my network via wireless Tivo adapters. In the past, I have noticed that each of them appear in the other's "My Shows" list. i have purchased a new router and noticed that they no longer appeared I rebooted both of the Tivos and the Series 2 appeared in the Premier's My Shows, but not vice versa. How is this mechanism managed? Is it possible my new router is the problem or should the router not matter?

    Thanks for any info on this.

    Which is why I'm asking if anyone knows what the mechanism is and if the router could be at fault. I see entrys for both Tivos in the router's "attached devices".

    The new router is probably blocking the broadcast packets that your TiVos use to find each other. Look through the router's advanced settings and make sure that it isn't blocking broadcast (or multicast) packets, and turn off IMP Snooping if it has a setting for it.

    In a router it's called IGMP Proxying. From my Netgear:

    I don't any settings that refer to "multicast". The only reference to broadcast is the setting to broadcast the SSID. Not do I see any setting for IMP Snooping (whatever that is...) I see a checked setting to disable IGMP proxying and I don't know what that means, either. Response to ping is disabled. There is something called WMM (Wi-Fi multimedia), which is enabled for both bands.

    I have a NetGear Dual-band gigibit router--R6220. I upgraded to this router to enable 200 Mbps speeds. My previous router was only "Fast Internet" and was bottlenecking my network.

    I'm happy to report that my Premier has now shown up on my Series 2. I sure would like to know the under-the-hood details of how this works...

    The visibility of the other Tivo boxes seems to randomly appear and disappear... it's driving me batty! Is there no documentation discussing this somewhere?

    From the Premier 4 manual: "Disable MoCA (Wireless N only) The TiVo Wireless N network adapter will not work properly if MoCA is enabled". The last sentence in that paragraph is "Note that if you want to stream shows to/from other TiVo DVRs, a wired connection (Ethernet or MoCA) is required." I use the Tivo Wireless N adapter on my Premier and a wireless G adapter on my Series 2 and have been able to copy shows back and forth.
    What a I missing here?

    I have a couple of questions which someone may know here:
    1) Is "streaming" different than transferring a recording from one Tivo box to another? If so, that would explain the apparent conflict I reported in my last message.
    2) Is UPnP used to provide connectivity to the Tivo boxes on a local network?

    Nice brevity! I would like to clarify question 2) a bit. I know that each wireless adapter connects to the router via the SSID. What I meant by the question is whether the appearance of the boxes on each other's My Shows list depends on UPnP. I think you might have surmised that this was what I was asking... just want to be sure. Yesterday both Tivo boxes were present on each other's My Shows; this morning they disappeared on both of my Tivos. This is very frustrating. Thanks!

    The TiVo discovery processes uses UDP broadcast packets, not UPnP. They can be the old proprietary TiVo Beacon format that uses port 2190, or Apple's Bonjour protocol (MDNS) on port 5353.

    I would try rebooting the router, then once it's stable reboot the TiVos one by one.
