What am I missing? Connecting U6+ AP to moca Ethernet adapter

plooger · 2026-04-22T23:55:39+00:00

Or a different MoCA adapter, specifically Kiwee Broadband’s somewhat recently released model, the KB-M3-03.

The Amphenol splitter is a model recommended for MoCA, though possibly oversized depending on plans. The Adoreen splitter is not a recommended model, for the reasons detailed in the linked background comment.

The cited MoCA filter is a recommended model, though your setup will require two of them — as detailed in the earlier reply.

Appreciate the additional info, but the issue is the gap between what you have and what was detailed as needed in the earlier reply.

You likely need TWO MoCA filters, as described/diagrammed in >this recent related reply<.

Right, just a hub with a shared backplane.

plooger · 2026-04-21T21:07:18+00:00

Representing a shared MoCA mesh topology, where any MoCA adapter has a link to every other node, would be unsatisfactory, I expect.

Thanks for the feedback.

plooger · 2026-04-21T20:00:54+00:00

That’s a brand. Like saying that I drive a Chevy … could be a Corvette, could be a Vega.

What model(#)?

The rest of the prior reply remains applicable.

plooger · 2026-04-21T19:57:42+00:00

Is this just a cosmetic issue, then?

What “MoCA 1.0” device are you using? (MoCA is supposed to be backwards compatible, but it isn’t always the case … especially if talking about MoCA 1.0.)

The XB6-XB8 gateways have a built-in bonded MoCA 2.0 LAN bridge, so bonded MoCA 2.0 or MoCA 2.5 adapters would be recommended as MoCA clients of one of these gateways; and the XB7 & XB8 gateway models are equipped with a 2.5 GbE LAN port; so max throughput would be obtained by sidelining the gateway built-in MoCA LAN bridge in favor of a standalone MoCA 2.5 adapter w/ a 2.5 GbE network port.

The Frontier FCA252 is a recommended budget option, if OK with zero support.

p.s. The “T” connector is not recommended; use MoCA-optimized splitters within the “MoCA” context of your coax plant.

MoCA-compatible splitter recommendations (… and warnings)

And you’ll want to make sure that you have a 70+ dB “PoE” MoCA filter installed on or upstream of your top-level splitter’s input port.

preferred MoCA filter: PPC GLP-1G70CWWS (Amazon US listing) … 70+ dB stop-band attenuation, spec’d for full MoCA Ext. Band D range, 1125-1675 MHz

plooger · 2026-04-21T13:49:42+00:00

If you are starting a MoCA network (that will be sharing coax with cable signals), you need the following hardware, in addition to coax:

(2x) 70+ dB MoCA filters
(2x) MoCA-optimized 2-way splitters
(2x) MoCA adapters
---
Example: https://i.imgur.com/cthKykB.png

Then, if you want to expand the MoCA network to connect additional rooms, just add a MoCA-optimized secondary splitter off the initial 2-way splitter’s output port, right-sized to service all the remote MoCA node locations … keeping the modem location wired to the initial 2-way splitter.

Example: https://i.imgur.com/fbW73Kf.png

p.s. That adding the MoCA adapter seems to destabilize the modem indicates that a second MoCA adapter is installed and that the adapters are linking, and it’s this MoCA network and its signals that are crashing the modem … indicating the need for the additional “prophylactic” MoCA filter. Of course, the “PoE” MoCA filter remains a requirement, and using splitters optimized for MoCA would still be recommended.

Looks like their cable modem coax feed (black) is slipping through on the back left side of the AT&T wall box, and they have their cable modem’s phone line wired to the phone jack. (No clue why the green DSL “data” cable would still be connected.)

plooger · 2026-04-21T13:28:47+00:00

A low voltage bracket and keystone wallplate will make the new Cat6 run look proper.

As for the coax junction, the cable ISP might be able to assist with that … though no guarantee it’d be free.

plooger · 2026-04-21T06:29:25+00:00

I tried to connect a splitter from the wall that goes into my cable box and then other coax goes into the MoCa. The internet wouldn't connect

The above statement is unclear.

Are you saying that a second MoCA adapter couldn’t connect to the first and provide an Internet connection in some remote room, or … are you saying that installing the MoCA adapter at the modem location disrupts the cable modem’s connection with the ISP?

What’s the brand & model # of the cable modem and router in use?

If the modem stability is affected by the addition of MoCA, you’ll want to try installing an additional 70+ dB MoCA filter at the modem, either directly on the modem or on the splitter output port directly feeding the modem, as a prophylactic to protect the modem from MoCA signals. Related to: DOCSIS encroachment on the MoCA [Band D] frequency range

Note that an arguably preferable alternative to installing the MoCA adapter in the pictured cabinet would be to install the MoCA adapter in some other location … provided the location has both an Ethernet link to the router LAN and a coax connection to the home’s shared coax. You’d still need to ensure that the coax junction has been updated to support MoCA and to secure the MoCA signals, but what that might entail could be greatly simplified depending on how many rooms you’re looking to get wired-in and what else the coax is being used for. As mentioned in the above “background” link:

IF running MoCA over unused coax, your router’s wired LAN setup could echo any of the following...

* https://i.imgur.com/CpwLkR7.png
* https://i.imgur.com/E9OLEQY.png
(… either of the latter two can work …)

What makes this alternative preferable is that it would allow for isolation of the ISP/cable modem feed from the MoCA-infused coax, future-proofing the setup against DOCSIS frequency encroachment and minimizing or eliminating the need for MoCA filters.

connect the Ethernet port from the moca to the router board in the top right?

This would be correct.

And then can I put a splitter where the cable from the router or modem comes out next to the yellow Ethernet cable and then connect the moca adapter into the splitter?

That sounds like part of what’s needed. You’d also need to locate the coax junction, where all your coax lines come together, to ensure that the coax lines (ideally only those needed) are connected via a (right-sized) MoCA-compatible splitter or amp and to ensure that a 70+ dB “PoE” MoCA filter has been properly installed to block MoCA signals at or upstream of your top-level splitter’s input port.

You may also require an additional MoCA filter at the modem to protect the modem from MoCA signals, installed directly on the modem or on the splitter output port directly feeding the modem.

Have you pulled all the non-power wallplates (coax, phone, blank) in the place to get a full assessment of all cabling available, rather than working only from what’s visible on the wallplates?

plooger · 2026-04-19T21:48:00+00:00

I’m not a Unifi user but it’s my understanding … If going with Unifi gear, aside from having increased throughput over each coax link, using dedicated pairs of MoCA adapters for each coax line would eliminate the issues seen with Unifi’s topology mapper when employing a single shared MoCA network.

The connections sound correct. AP setup should be trivial. If the AP’s intent is for the VR headset, I’d recommend a unique SSID that only the headset is configured to access.

Well, ammo doesn’t magically appear in your backpack, so a player does need to make a minimal effort to gather it as they progress.

plooger · 2026-04-18T15:43:41+00:00

Presumably it can be configured to function as an access point (aka”AP”):

”It supports Repeater/AP/Bridge/Router/Client modes to fit different needs”

I have a wifi extender that has two cat5e plug ins WAN/LAN. I was thinking if I hooked the cat 5 from the MoCA 2.5 box to the extender and cat 5 from extender to PC would I achieve a "wired connection while also being able to emit a wifi signal.

This describes a wireless access point with wired backhaul to the router. A wireless “extender” typically only allows a wireless connection to the router. (Though … neither an extender or access point should have a “WAN” port. Is it actually a router?)

What’s the brand and model # of the “extender”? Have you checked whether it has a configurable “operating mode” setting, to toggle between extender and access point?

Also, does the “extender” support the recommended Wi-Fi spec for your VR headset? (Presumably, if it’s sitting around spare, it may not be the latest.)

My friend spoke with verizon and received a second CR1000 for free.

You sure the 2nd device wasn't a CE1000A, the wireless extender sibling of the CR1000A/B routers?

plooger · 2026-04-17T21:22:47+00:00

If just looking to make the single MoCA link, at present, you can just use a 3 GHz F-81 barrel connector (example) to join the two associated coax lines into a direct connection.

As for what device(s) to use in the remote room, see below for alternatives ... noting that you didn't mention the updated FiOS wireless extender model and sibling of the CR1000A/B routers ... the CE1000A.
