Re: CODA-4582 MoCA 2.0 setup

Is your whole home PVR working now?

 

If so, I would reinstall the MoCA filter as there are probably other customers in your neighbourhood who also have the same PVR configuration.  You don't want to access their PVR system and you don't want them to access your PVR system.  

 

Now, if you are no longer using the whole home PVR, then you can leave the filter off. 

 

However, to run your own MoCA network, you need that filter installed.  

 

If you have the whole home network running, you will have to log into each MoCA adapter and select the D-High band to stay out of the way of the Whole Home network in the D-Low band.  Don't forget to encrypt the adapters as well.  They should have a privacy setting or code entry window to do that.

Re: CODA-4582 MoCA 2.0 setup

The whole home PVR is working now. Wonder why the Rogers tech stated that it was needed.

I will re-install the filter and see if anything changes. I won't get the MoCa adapters until mid-March so will report back then.

Re: CODA-4582 MoCA 2.0 setup

You shouldn't see any difference with the MoCA filter installed.  All that does is act as a low passband filter, which allows 5 to 1002 Mhz to pass thru for normal cable ops, but cuts off the higher MoCA frequencies above 1002 Mhz.  That cut off is both ways, nothing inbound towards your network and nothing outbound towards the Rogers network and your neighbours networks.

Re: CODA-4582 MoCA 2.0 setup

About to purchase a 3-way splitter and am looking for a recommendation.  I found the following on Amazon.com which look similar... which one is the winner?  All are priced $13US or lower so price is not a factor for the recommendation (for me).

Re: CODA-4582 MoCA 2.0 setup

For now, stick with the MoCA qualified splitters.  That way you will know that the internal port to port frequency range will support MoCa 2.0/2.5.  The other splitters have a higher frequency range, but, just thinking aloud here, without checking the specs, you don't know if the internal port to port frequency ranges will support MoCA 2.0/2.5.   It might be that the higher frequency ranges are a one way path only, input to output.  

 

So, I'd simply go in the order that you specified in your post:

 

3 Way Antronix MMC1003H-B 5-1675 MHz MoCA 2.0 Splitter:

https://www.amazon.com/Antronix-MMC1003H-B-Splitter-Frontier-Formerly/dp/B07PMLCVHQ/

The balanced splitter might be useful depending on what splitter you have in place now and what your modem signal levels happen to be.  If you have an signal average higher than say 3 dBmV on the downstream side, then using a balanced splitter will drop that by 2 dBmV.  The upstream will go up as well.  As long as your upstream isn't higher than 40 dBmV as a guess, then you could use the balanced splitter.

Re: CODA-4582 MoCA 2.0 setup

How would I measure the signal (I have no equipment)?  

 

If the difference is marginal and likely not noticeable, I think your reco to go with the Atronix is likely the right decision.

Re: CODA-4582 MoCA 2.0 setup

If you log into your modem and check the signal levels, that will tell you if you could use the balanced splitter.  

 

The Hitron 4852 will only show the DOCSIS 3.0 channel signal levels for channels 1 to 32 downstream and the 3 or 4 upstream channels.  It does not show the DOCSIS 3.1 Downstream OFDM channel signal level. 

 

The XB6 modems will show the DOCSIS 3.0 channels, downstream and upstream, and the DOCSIS 3.1 OFDM channel as well. 

 

So, in either case, if the DOCSIS 3.0 signal levels averaged + 3.0 db or higher, you could use the balanced splitter. As I indicated earlier, if the upstream wasn't higher than about 40 dBmV, you could use the balanced splitter.  

 

Using the balanced splitter for the Nextboxes or Home Phone modem would bring those downstream signal levels up by 2 dB and bring down the modem's downstream signal levels by 2 dB.   

 

In any case, we're only talking about 2 dB difference, which could be measured with the modem or Nextboxes.  Its not a large difference however.  Just pointing out that you could check the signal levels and go from there.

Re: CODA-4582 MoCA 2.0 setup

@rmann2020 thats not looking good.  You have some DOCSIS 3.0 channels, 2, 3, 4, 7 indicating a default signal to noise ratio and the OFDM channel isn't running.  Can you reboot the modem and repost the table after the reboot.  Looking at the remaining DOCSIS 3.0 channels, their not too bad, but I wouldn't want to decrease them any further.  Do you have a splitter in the system now and if so is the modem cable connected to a -3.5 or -7 dB port?

Re: CODA-4582 MoCA 2.0 setup

@Datalink - my setup was described on message 38 and 39 has pics of my splitters. https://communityforums.rogers.com/t5/Internet/CODA-4582-MoCA-2-0-setup/m-p/451106#M57982

 

But a picture is worth 1000 words... so here's my attempt at my Current Home Network diagram:

Current Home network diagram (3).png

Note: there may be other connectors/splitters in the walls which I'm unaware of and likely will never know.

 

Future Home Network changes once MoCA adapters installed:

When I receive the Gocoax MoCA adapters, I plan to move the Rogers modem, Gateway and Switch to the basement, use one MoCA adapter in the basement and a second adapter in the second floor.  The wireless AP will also be moved to the second floor at that time.  As such, the current Female to Female connector and 2-way switch in the Family will no longer be needed.  I will also swap out the current 3-way splitter in the basement with whichever splitter you recommend.

 

Now that you have the full picture (pun intended) and my current specs, does any advice change? (i.e. splitter, filter, installation, specs, etc.)

 

I will reboot the modem shortly and report back with updated results.  I will re-add the MoCA filter at that time as well.  This will still be done in the current configuration though.
