The problem is that many Tivo issues I've run into can be very hard to diagnose and figure out; so why not go with best practice? The folks here are saying you need it there, and people aren't having problems if they follow the advice, so I've got a POE filter there!
Because I'm extremely cheap. My system works fine at the moment. When I put a Moca signal on the TA, I'll know right away if it caused a problem. I just wanted to know if there was a 100% chance Moca would interfere with my TA or not.

Sounds like I can just try it and see. If, worst case, there is permanent damage, I can just get another TA and add a filter next time.
That's one option. And it is in-line with the following advice included in the TiVo Custom Installers Tips & Tricks document:

SDV Tuning Adapter malfunctions: Not all cable systems use tuning adapters, but some will. If your SDV tuning adapter isn’t working when activating MoCA, try installing a second POE filter (in addition to the one mentioned above) on the coax line going to the tuning adapter.​

FYI... Here's a recent post I made offering advice on the subject to another TCFer, including links to one report of tuning adapter issues owing to MoCA and the "official" Cox tuning adapter installation doc, demonstrating the MoCA filter installation.
... do you have a tuning adapter from TWC connected to your Roamio Pro?

If so, you must be aware that the "TV/RF Out" port of tuning adapters (TA) do NOT pass MoCA signals, so a MoCA-enabled device daisy-chained off a TA's TV/RF Out port would not be able to communicate via MoCA. As joestan indicated, you would need to use a 2-way MoCA-compliant splitter to feed coax to the tuning adapter and Roamio Pro separately; in addition, to protect the tuning adapter from the MoCA signals (see here), you would also need to install a MoCA filter on the coax input to the tuning adapter.

See Step #5 in the Cox tuning adapter setup document for a good diagram showing how to properly connect a TiVo and tuning adapter in a MoCA environment (excluding the Ethernet connection you will require for the TiVo). And, yes, this connection setup applies to TWC tuning adapter installs, as well.

It *would* have been nice had we developed a list of known-good/-bad tuning adapters in regards to MoCA. Let us know how yours works-out, and maybe we can start that list/post.

If you just connect your TA to the output of your moca adapter's pass through then you don't have to worry about a filter, since there's an internal diplexer in it, in that instance. ;)

I agree, but isn't there really only 2 that are in use depending on the headend brand? The Motorola/Arris MTR700 and the SA/Cisco STA1520? I'm not familiar with any other models.

No clue, not ever having had to use one, myself. There are only a few, I expect, and was looking for mdavej's feedback to perhaps seed an/my effort to go track down any other models mentioned and easily located in past threads.

The point is, you had to ask, right, versus being able to simply reference a known-good/-bad list.

Exactly! :up:

Not much to report as my new modem didn't work with my provider. But I did have Moca on the line for a few minutes, and my Moto TA apparently stayed connected, sans POE filter. Cable company claims they will support my modem in a few months. So I plan to try again then.

EDIT: I managed to snag a filter for under $3. I can deal with that.

Just a question if the following connection would work with a Tivo Mini. I currently only have a Tivo Roamio OTA with Tivo Stream. Current connection is modem---Airport Extreme---switch---Roamio OTA (switch also connects with a separate cable to Tivo Stream). The mini would connect modem---Airport Extreme---Airport Express---Mini. The Airport Extreme is hardwired to both the switch (used for Roamio OTA and Stream) and the Airport Express. Would that connection work to connect Roamio OTA to a mini, or would they not be able to "see" each other, necessitating a Moca setup? Thanks.

As mdavej indicates, for an officially supported solution the Mini would need to be hard-wired, via Ethernet or MoCA.

I would think the AirPort Express would need to be configured in AP Mode and its Ethernet WAN port repurposed as a LAN port for your suggested configuration to work. Otherwise, you'd need to replace the AirPort Express with an Ethernet switch, to which both the Mini and AirPort Express could connect.

edit: p.s. This wikipedia comparison chart indicates your plan would work with the latest AirPort Express.

I don't see why not. Give it a shot. I don't know exactly how an Express works, but I assume you would hard wire the Mini to it somehow?

He did say that his express is hard wired:

Being hard-wired can be moot when bringing another router into the mix, thus the emphasis on repurposing of the Ethernet WAN port and AP mode. Just daisy-chaining the AirPort Express and Mini off the Extreme using Ethernet cables won't get the job done; the AirPort Express will need to be properly configured so that it's two (2) Ethernet ports are on the same LAN.

I agree and it was a great suggestion telling him that. I was merely clarifying that his scenario is all being wired because it seems like that wasn't understood by what was written.

AP mode is for wireless, for example.

I believe the way I have it set up now is the AirPort Express is using 1 port as WAN (connected via ethernet to AirPort Extreme) and the other as LAN. From the advice, it sounds like I should connect the AirPort Express wirelessly to the AirPort Extreme and have both port on the AirPort Express used as LAN. If I understand correctly, the switch in between the AirPort Extreme and the Roamio does not change it to a different LAN?

Definitely not, no, negatory, uh-uh, newp.

Can you get into your AirPort Express and report back with the different "modes" it offers (e.g. "Router", "Bridge", "Client", "AP", "Access Point", ???), and which is currently set?

If I understand correctly, the switch in between the AirPort Extreme and the Roamio does not change it to a different LAN?
That's correct. And it may be what you need to do to connect to your Mini, as well, if we can't get the AirPort Express properly configured: wired to the AirPort Extreme, but configured such that both of the AirPort Express' Ethernet ports are on the same LAN.

I'll see what I can find re: AirPort Express documentation in order to get the terminology correct.

The mini would connect modem---Airport Extreme---Airport Express[WAN]---Mini.
Getting a bit more explicit with the connections, they'll be wired:
modem[ETH] --- AP Extreme[WAN] / AP Extreme[LAN] --- AP Express[WAN] --- Mini[ETH]​

And it looks like configuration should be as easy as setting "Connection Sharing" to "Off (Bridge Mode)" on the AirPort Express.
Note that some articles refer to the configuration option as "Router Mode" rather than "Connection Sharing."

Read on and review the linked articles for details...

BACKGROUND:

See: Wi-Fi base stations: Extending the range of your wireless network by adding additional Wi-Fi base stations
Multi Wi-Fi base station network - A network that utilizes more than one Wi-Fi base station to extend the range of a network, or to extend features such as Internet access, music streaming, printing, storage, etc. The Wi-Fi base stations may be connected together via Ethernet or wirelessly.

Roaming Network (Ethernet-connected Wi-Fi base stations)
  • This set up requires that your Wi-Fi base stations are connected via Ethernet.
  • The primary base station provides DHCP Services, while the extended base station will be configured to use bridge mode.
  • All Wi-Fi base stations within the roaming network should use the same passwords, security type (Open/WEP/WPA), and network name (SSID).

HOW-TO:

See: Wi-Fi base stations: Setting up and configuring a roaming network (802.11 a/b/g/n)
Set up: Connecting your Wi-Fi base stations together

Use Ethernet to connect from a LAN port of the primary Wi-Fi base station to the WAN port of an extended Wi-Fi base station. The primary base station is the base station connected directly to the Internet.

To configure a roaming network

  1. Power on all 802.11n Wi-Fi base stations and allow them time to appear in the AirPort Menu Extra.
  2. Open AirPort Utility (On a Mac, choose Go > Applications from your desktop, click the Utilities folder, then open AirPort Utility. In Microsoft Windows, choose Start > All Programs > AirPort to start AirPort Utility).
  3. If you are configuring the primary Wi-Fi base station, set Connection Sharing to "Share a public IP address."

    If you are configuring the extended Wi-Fi base stations, set Connection Sharing to "Off (Bridge Mode)."
  4. Use AirPort Utility to configure the Wireless Network Name, security, and password on each Wi-Fi base station to be exactly the same.
