2x GoCoax MoCA 2.5 Adapters - not connecting

in Everything for MoCA

Hello,

I purchased 2x GoCoax MoCA 2.5 Adapters. I'm having problems having the two adapters connect on the network.

The first GoCoax adapter is setup next to my router. This was the first adapter that was connected, and it appears to be working well – the power, MoCA, and LAN lights are all on. The only changes to the default configuration are as follows:

• Assigned a new IP so that the GoCoax can be connected to my network.

• Changed the administrator password.

• Changed the GoCoAX name to "Den" instead of the default, Master.

The second GoCoAX adapter was setup in a similar way, and it installed in the basement. The problem here is that the MoCA light isn't coming on. It has been installed for over 30 minutes, and I don't think this is a case of the two adapters not having enough time to "find" one another.

I've also tested the coax lines with a tester, and they all passed.

The coax wiring is setup as follows –

Please note: I have Verizon Fios, and my modem is setup in bridge mode so that I can use my own router instead of the Verizon supplied model.

Second note: each of the splitters used are Bi-Directional MoCAs rated for 5-2300MHz.

• The source coax comes from the Verizon box in my basement – this is split with a 2-way splitter:

1. To a bedroom on the 2F (unused)

2. To a 3-way splitter under the basement stairs

• The 3-way splitter is routed as follows:

1. To the (working) GoCoAX adapter, which is then passed through to my Verizon router in bridge mode

2. To the (not working) GoCoAX adapter

3. To another bedroom on the 2F (unused)

Can you please advise on how to resolve this issue?

Thank you

How did you assign a new ip address. How did you connect to the gocoax device.

Ethernet cable connected from gocoax to router also.

My gocoax adaptor hasn't connected to moca on the spectrum router. I have used a splitter for the coax coming in to be split with the gocoax out and then out to router. So luck of it showing moca light.

Ethernet WAN: It comes from the basement modem (I assume), plugs into the G1100, then the ethernet cord is routed directly to my Asus router. Sorry for the extended mystery! :-)

Also, the modem in the basement – that was here when we moved in. Should that be updated eventually or is that something that I shouldn't worry about?

Also, regarding the router, I found this in my email:

Rent: Fios Quantum Gateway Router - $12 per month no charge thru Aug 25, 2022

So, that definitely happened. I think that they said the router was also needed to role out updates . . . something. I don't know what, but I was pissed about it – hence the "no charge" through next year.

Ok, I'll leave that to @J. C.. You definitely can't eliminate the G1100 until the Ethernet WAN link is direct between the personal router and ONT. (And that's definitely a question for the Verizon forums.)

Thanks for the extended feedback.

If the cable cards really need the G1100, then it should only need to be activated once. Once activated, G1100 can be taken out.

Regarding the Fios-G1100: I'm sure it is needed. I know it sounds crazy, but initially, I didn't have it in the setup and there were some issues. I can't remember what it was exactly because that was nearly 2 years ago now.

You know, now that I think about it: it has something to do with the Cable Card in the Tivo Bolt – I think it couldn't activate it, or something. It was extremely irritating, and like I mentioned: they gave me some sort of discount to offset the G1100 monthly rental fee.

Fios is odd – I was helping our neighbor with his box the other day and was surprised to see a Cable Card within it. It wasn't "user accessible" but you could clearly see it through the holes in the enclosure. I had no idea that Verizon used Cable Cards in their standard set top boxes.

All this makes me miss the simplicity of my family's 1980's Scientific Atlantic analog tuner. :-)

I hear what you're saying, and I can't say anything authoritatively without the answer to the question Re: the source of the router's Ethernet WAN connection, but with the prior IF conditional still applying, I'm familiar with TiVo's and a FiOS router isn't required for TiVo CableCARD activation. (I've heard that it *is* the case for some new-fangled FiOS "One" boxes; but it's not the case for TiVo's.)

Simple enough to test when you can spare a brief outage if I'm wrong ... by powering off the G1100. (Again, presuming an Ethernet WAN connection between your router and the ONT, the answer to which remains a mystery.)

edit: p.s. With an Ethernet WAN connection, and the G1100's MoCA LAN disabled, there wouldn't be any way for the TiVo to communicate with the G1100 at this point.

I guess that option was not too tedious to find. In case you want to take out the G1100 and repurpose it for other purposes, we can continue this thread.

Otherwise, your case can be summarized as follows:

Two goCoax 2.5 try to co-exist with Fios-G1100 MoCA 2.0 unbonded LAN. Compatibility issues between these devices.

Solution: disable Fios-G1100's MoCA LAN interface in GUI.

More simply put... the OP was trying to use a standalone MoCA adapter as their main MoCA/Ethernet bridge; therefore, the G1100's built-in MoCA LAN bridge must be disabled.

<<insert how-to here ;) >>

Supplemental: If MoCA LAN was the only function still be provided by the G1100, then the G1100 can be removed from the setup once its MoCA bridging functionality has been successfully replaced.

Well done. Way to mine for the proper configuration setting.

Hello,

I was able to get this working. In my Verzion router settings I navigated to:

MY NETWORK > NETWORK CONNECTIONS > NETWORK (HOME/OFFICE) PROPERTIES > UNDERLYING DEVICE > COAX

• I disabled this, and it fixed the issue.

I then tested the MoCA adapter – very impressive: the speedtest was near 999 MBPS.

Thanks again for your assistance!

If this was an Internet speed test, rather than a test between two LAN devices, then it would indicate that your router has an Ethernet WAN connection with the ONT. Can you trace the network cable connected to your router's Internet/WAN port and report back as to where it runs?

'gist: *IF* you have an Ethernet WAN connection between the router and ONT, and you've now disabled the MoCA LAN in the G1100, the G1100 truly serves no purpose and can be removed from the setup.

With things working, it might be a good time to take another look at the MoCA diagnostics, to see what they say and save the info/screenshot as a comparison against future issues or changes.

The OP, to check what WAN connection you have, just login to G1100 and check the left side at the home page, whether it is Ethernet or Coax Connected. Or, go to your ONT and see whether the MoCA LED is illuminated.

Your post says nothing about what is connected to your personal router. An Ethernet cable must be connected to its Internet/WAN port; where is this Ethernet cable coming from?

TiVO guide does not need a Verizon router. Only when you are using Verizon STBs and want to access the DVR remotely then you would need a Verizon router.

Right now, in bridge mode, G1100 is essentially acting like a switch. It does not inspect the network packet or do anything network related.

Do you have an Ethernet coming from the ONT to your G1100? If so, just unplug the coax cable to G1100. You can disable the MoCA LAN in the GUI, but still too tedious to find that option.

J. C.

Jun 25, 2021

The OP, since you are not Verizon STBs. The G1100 is not even required. You can repurpose as an access point and/or MoCA adapter.

I see the solution is either take out the G1100, or disable the LAN Coax interface on the G1100. Or, just unplug the Coax going to the G1100 if you have an Ethernet coming from your ONT to G1100.

@ploog If OP uses MoCA WAN, the connection speed must be 100/100 or less, which are all legacy packages. Mix and Match 300/300 is generally cheaper than 100/100 or 75/75, so conversion to M&M is another task to embark for the OP.

goCoax produced Frontier adapter should be able to operate at Channel C4 (1000MHz).

@J. C. I understand how things are *supposed* to be; I'm trying to understand how things *are*. (It's not impossible that the OP's configuration isn't optimal for the speeds that they're paying for.)

I wouldn't mind discussing the FCA251/WF-803FT separately.

Replying to

@ploog Yeah, I agree that the optimal setup may not be the actual setup. I guess we could bring the OP's setup to an optimum (as a none, not the ISP) when solving the MoCA issue along the way.

Do you have any MoCA filters on-hand?

If so, you should try installing a MoCA filter on the input of the 2-way splitter, your top-level splitter. (I have *some* concern about the effect of the MoCA WAN signal passing through both the MoCA filter and the pass-through port of the MoCA adapter. A 2-way splitter could be used at the router location to connect the adapter and FiOS router, if needed.)

---

As an additional experiment...

Given the unused coax lines, have you considered simplifying the setup, at least temporarily? For example, the coax could be reduced to:

1. Using a F-81 barrel connector, ONT coax line is joined to the coax line leading to basement stairs junction;

2. Coax coming from ONT location is connected to the input of a 2-way splitter;
