goCoax MoCA 2.5 adapter

[eng3]

I also tried connecting through MOCA but with a 2ft RG6 and here is what I get:

I tried connecting the laptop directly into the router and here is what I get:

So it seems like the MoCA stats again match the Ethernet stats. MoCA can't improve the performance of your Ethernet connections; whatever ails your network, keeping you from Gigabit speeds, appears to be outside your MoCA segment.

 

[krkaufman]

Dear @gocoax , any chance of MoCA adapters being capable of VLAN tagging and filtering?

​

 

[degrub]

they should be transparent to VLANs. That functionality would be provided by a managed switch, before or after the MOCA coax network.

 

[Samir]

they should be transparent to VLANs. That functionality would be provided by a managed switch, before or after the MOCA coax network.

Not necessarily. Most unmanaged devices will strip the vlan tags. I have found the netgear av500 nano powerline adapters will actually keep the tags for up to 12 vlans. Would be nice for moca to do the same.

 

[degrub]

i don't know of any issue with 4 vlans over my Actiontec 6200s on my internal network so far. My GoCoax pair are only being used for the interface from my ISP router to the ISP fiber modem, so no vlan applied at that point.

Any data that indicates otherwise on Actiontec ?

That's good to know as most of these all will work to the same moca specs, so the moca specs may incorporate vlan support.

 

[degrub]

i don't know what is in the MOCA spec anymore. Last time i read it, it was on 1.0/1.1.

 

[krkaufman]

That functionality would be provided by a managed switch, before or after the MOCA coax network.

Understood that that is what is required, at present; was just curious as to the possibility of the capability (tagging/filtering, not just maintaining VLAN tags) being available in some version of a goCoax MoCA adapter in the future. (Aside from putting non-spec functionality into the device, I expect that there just isn't sufficient market for doing so. But still curious.)

 

[Leecm0365]

I am preparing to setup up a home MOCA network. I got 4 GoCoax WF-803M adapters.

trying to rap my head around how to transition current networks to new networks using moca adapters.

current setup I have a Nighthawk router as on network (10.0.0.1) and a Belkin router on another network (192.168.2.1). Both the routers have WAN ports connected to LAN ports on Verizon router which is connected to Verizon ONT via coax cable. See pic for current network setup and planned network using moca adapters.

I just cannot see the IP settings working and think I need to change all my IP addresses on all routers to be on same subnet. Looking at planned network do yawl think I need to change IP addresses?

 

[krkaufman]

(probably better served creating a new, separate thread, as your issue isn't specific to the goCoax adapters ... and so you may get more eyes on the issue as a new thread, appropriately titled)

 

[Trip]

@Leecm0365 - Per @krkaufman, I'd create your own thread on this. Re-post your topology graphic there, and I can re-work it to show you how you'll want to setup your new network.

I made new thread Thankyou

Looks like the performance is limited by the Computers. You know, some older computers can't get full speed.

Dear @gocoax , any chance of MoCA adapters being capable of VLAN tagging and filtering?

View attachment 28387​

Hello, I think you want to distinguish the WAN and LAN service with different VLANs over the same coaxial network.
Sorry, the current MoCA chip is very weak. It only can pass VLAN traffics, can't do VLAN adding/Removing and Filtering.
But We have another solution. You can use a pair of MoCA adapters for WAN.Other MoCA adapters for LAN. They are different MoCA adapters.
If you can do some soldering, I can tell you how to change the hardware to support this.

 

[gocoax]

I am preparing to setup up a home MOCA network. I got 4 GoCoax WF-803M adapters.

trying to rap my head around how to transition current networks to new networks using moca adapters.

current setup I have a Nighthawk router as on network (10.0.0.1) and a Belkin router on another network (192.168.2.1). Both the routers have WAN ports connected to LAN ports on Verizon router which is connected to Verizon ONT via coax cable. See pic for current network setup and planned network using moca adapters.

I just cannot see the IP settings working and think I need to change all my IP addresses on all routers to be on same subnet. Looking at planned network do yawl think I need to change IP addresses?

Please don't connect the DVR/TV to the TV port of our product. Because DVR is using MoCA. But the TV port has filtered the MoCA signal. Please use a two way splitter in the Family Room and Living Room to connect MoCA adapter and DVR.

If this is something other than configuring each pair of MoCA adapters for D-Low and D-High, I'm definitely interested in this new-to-me approach.

p.s. Thanks for the reply on VLANs; it's the answer I expected, but wanted confirmation. I thought, perhaps, that it might be something possible, separate from the MoCA chip/firmware, that you could apply at the Ethernet interface, but understandable that it's not on the roadmap.

Looks like the performance is limited ...

Speaking of limiting performance, reviewing this image on your main web page regarding MoCA and DOCSIS 3.1 ...

... the MoCA 2.0/2.5 spec:

The MoCA 2.0 frequency plan defines, within the new extended band D, two sub-bands for independent network operation. These sub-bands comprise the D-low and D-high, as follows:
* Sub-band D-Low (DL): 1125 to 1225 MHz edge to edge (100 MHz wide)
* Sub-band D-High (DH): 1350 to 1675 MHz edge to edge (325 MHz wide)
* Guard-band between sub-bands: 1225 to 1350 MHz (125 MHz wide)

... and the goCoax support page:

Does the admin GUI also allow configuring the MoCA frequency channel you want the extenders to run on?
Yes, our products can support this. Our device can support MoCA D-band low, D-band high and D-band extend three configurations. By default, we enable all of them. It will setup a 5-channels connection, from 1125MHz to 1625MHz. We know that, many MSO use D-band low 1125MHz to 1225MHz to act as MoCA WAN. You can change our device to use D-band high only, from 1350MHz to 1675MHz, can build a 3-channels connection.

Can the goCoax adapters be configured to work optimally with DOCSIS 3.1 signals present on the same coax? Setting the adapters to use D-High would limit the number of channels bonded to just 3, while the MoCA spec indicates that the adapters should be able to use the 1275-1675 MHz range to get 4 channels bonded, only 1 short of the maximum.

p.s. Extra credit if you can link to somebody that sells (retail!) a "PoE" MoCA filter with a pass-band though 1218 MHz and stop-band of 1275+ MHz.

Sorry to kick an old thread, but I ran across this when asking the same question about getting 4 bonded channels with the goCoax adapters. I found that selecting D-Ext and D-High (unchecking D-Low), and setting LOF to 1275 gives me 4 channels. I can have two laptops each sending data to each other at nearly 1Gbps simultaneously even without the 5th channel. Also works with LOF at 1250, but in that case I was getting a few Rx Bad packets showing up.

In my setup, I only have D-Ext enabled, and the phy rate has always been above 3000.
