    Can anyone tell me why my Roamio can connect to the TiVo service and successfully download all information, but then claim the box is not connected to my network and therefore cannot see other devices (a Bolt+ in another room)? I can get a clean internet connection from the ethernet port where Roamio is plugged in, and Bolt is already connected to the same whole-house network in another room (house was wired 20 years ago with cat. 5 and all ports have been fully functional; all still appear to be.). I would like to be able to “see” both boxes at both locations and watch shows on either from either location, as I used to be able to do.

    I'd try an entire Network Reboot.

    Bring the Router back up 1st, allowing it to fully reboot.

    Then 1 TiVo at a time (and any required Switches), allowing each to fully reboot before moving to the next.

    Report back...

    Have done something similar, although not with the degree of individual control you have specified, especially with the ethernet switches. What caused all of this is that my cable modem "died" and I replaced it (hopefully temporarily!) with a leased one from Comcast. I did have some difficulty bringing all of the system backup, even though I brought the modem up first, then my WiFi router (which is significantly more powerful than the one built into the Comcast cable modem). I will try a reboot, but this time will power down all of the ethernet switches as well(one 8-port and one 4-port), plus several others scattered throughout the house at some of the ethernet outlets. I'll let you know what happens after that.
    I had contacted TiVo support and after over an hour on the phone, had no success in correcting this. He had me get new IP addresses several times, which makes some sense, but unfortunately did nothing to alleviate the issue. Thanks for the suggestions.

    OP Update: As per your suggestions, performed entire system reboot, including all ethernet switches. So far, basement TiVo mini cannot "see" primary TiVo Bolt in another room. I can connect a laptop to the wall ethernet outlet at the Mini and receive a fast, clean internet connection. I can also connect a laptop to the ethernet switch at this location and receive a clean connection. I can use the cable from the switch to the Mini, connected to the laptop, and get a clean internet connection (eliminates the ethernet cable as the culprit).
    Incidentally, there is also a DVD player with internet capabilities attached to that same ethernet switch which claims it has no network connection. (If I can get an internet connection to a laptop at that same outlet, how come the DVD player can't?!) Interestingly, either a TiVo mini or Roamio attached to the questionable connection completes the "restart box" command and claims all connections are good, but then claims it cannot see the primary TiVo box in another room.
    Given my (elementary!) network knowledge, I looked at the IP addresses of both the Mini (which cannot see the Bolt) and the Bolt, and they are different. I thought they needed to be the same (except for the last 3 numbers) for them to be considered on the "same network"?
    I have previously set up an older Roamio at the same location as the current Mini, and it goes through the "restart box" command fine. (Until I receive a requested cable card, it can't record or run "live TV". However, that will accomplish little for me as it isn't/won't be the primary box and remains "invisible" to the Bolt (and vice versa!).
    Before I replaced my (apparently??) defective non-Comcast cable modem, the Mini (at the same location as now) and the Bolt (also at its same, previous location) could "talk" to each other.
    Since I have clean fast internet connections at most of the "wall outlets" in the house, I must believe this is a TiVo issue. What "baffles" me is that the TiVo can complete its setup and when I test the Network settings on the TiVo, everything checks out "OK". Starting to wonder if the TiVo uses a completely different protocol to obtain its settings from the "service" than it uses to "talk" to other "boxes" in the house.
    Sorry to trouble you with this. Tried to "talk" to TiVo Support, but couldn't find "anyone home" even on the chat! Somehow I thought "Support" personnel could work from home. I have a relative who works on a "help desk" from home; at least they still have a job!

    They do. Here's my network status for one box:

    I have over a dozen devices on my network.

    Post those IP Address'!

    They should all be in the same Subnet.

    You probably ought to post all the model numbers of your switches.

    It sounds like maybe you're using an old Router as a Switch? (at a minimum), DHCP would need to be disabled on it.

    As KP said - everything generally has to be in the same subnet, and in a home, your subnet will generally be a /24, which means the first 3 octets of the IP addresses should be the same. e.g. 192.168.1.x -- only X should change.

    If stuff is getting different subnet addresses, that means you have more than one device doing DHCP (handing out addresses). This typically means you have more than one "router" on the network (because generally a router is the only device that hands out addresses in a house, at least in a place not run by an IT-savvy person).

    The likelyhood is that when you replaced the comcast box, they gave you what is usually referred to as a gateway, a combo modem router, rather than just a cable modem. Since you already had a router of your own, you now have 2 in operation. You might want to contact Comcast and see if they will put their combo device into "bridge mode" to disable the router on their device. But you will still need to reboot at least the router you own, and most of the Tivos.

    OP Update: Thanks for all the offered assistance; my apologies for the late update; holiday, maintenance issues, etc. Sorry for the long reply, but would like to respond to all kindly-offered suggestions.

    Old ethernet switches have been replaced with 1G-2G switches. Removed WiFi router as an intermediate ethernet switch. All ethernet connections now being supplied from same (16-port 2G) ethernet switch. No increase in speed noted at several outlets (PC’s attached, all different brands and ages). Primary TiVo continues to perform somewhat sluggishly (hard-wired to ethernet, not WiFi) but adequate for most use. Basement TiVo cannot “see” primary TiVo on another floor and claims ethernet connection has failed; beginning to suspect ethernet feed at that point. Even though I can get a fast, clean internet connection at that feed with a laptop, beginning to suspect that TiVo uses a different communication protocol than laptop and thus cannot “see” primary TiVo upstairs. I also suspect that TiVo Mini, originally used frequently at this outlet may not be faulty after all; maybe a “bad” ethernet outlet. Will reserve judgement on that later. Of course, getting a network “engineer” into the house for troubleshooting during Covid will probably not be possible.
    Have ordered two new Bolts under Memorial Day sale. Won’t bore you with details of how they will be deployed. One of them will replace the current Bolt+, which I believe has a defective hard drive as it occasionally (& unpredictably!) reconnects to the “service” on its own, during which any recording is lost. For those of you who requested TiVo box network settings, here they are:

    Great Room: (considered primary box).
    IP: 192.168.0.193
    Subnet: 255:255:255:0
    Gateway: 192:168:0:1
    Primary DNS: 192:168:0:1

    Basement: (used to have a Mini, now an older Roamio)
    IP: 192:168:0:144
    Subnet: 255:255:255:0
    Gateway: 192:168:0:1
    Primary DNS: 192:168:0:1

    Does the leased comcast cable modem have 4 Ethernet ports on it? If so plug two tivos directly into it and see if they can see each other. Plug in the minimal amount of equipment at first. If so keep adding in each switch and equipment, one at a time and see where the connection disappears.

    LarryAtHome: Would love to have done that several weeks ago! Logistically very difficult. All TV's are LARGE wall-mounted units and not readily movable. Leased modem does have several ports, but I believe one of them is reserved for VOIP phone and not useable for standard ethernet connection. Another of the ports has a red icon beside it and I cannot get a signal from it, leaving two ports for use. I still could do as you suggest, but would have to purchase a small digital TV to perform this test and I'm not inclined to do that. Thanks for suggestion anyway. I suspect mouse has chewed very long ethernet cable (installed during house construction) providing signal to non-functional outlet. If I'm correct, this one will be a "b**ch to replace! Thanks again, & stay safe.
