Re: CODA-4582 MoCA 2.0 setup

@Datalink 

 

Hi there,

I used the Sperry tracer (in one of the youtube video) for the testing, plugged the transmitter at end of the "tan color" cable in the basement, and used to receiver to check.

 

I got CLEAR beeping sound when testing one of the coaxial port at the main floor (which is the one I used for internet modem for the past one and half year) and one of the port at the second floor

All the remaining ports have the "constant static buzzing" sound but NO BEEPING.

 

So this proves the fact, there is a splitter somewhere? 

 

I checked all the air return ducts at main floor, no lucking finding the splitter 😞

So probably it is the wall somehow, at least some where not easy to find.

Re: CODA-4582 MoCA 2.0 setup

@alan4160 please ensure when you have the transmitter connected to one end of the cable, the other end of the cable is disconnected.  When you run the probe up and down the transmitter end of the cable when its connected in the basement, does it beep, due to any ability to receive the signal outside of the cable jacket?  You might have to increase the probe sensitivity to do this.  If so, then you might have the ability to follow that cable within the wall.  Don't run the tests solely at the wallplate locations.

 

Due to the splitter buried in the wall, you would have to do this from both ends of the cable.  That splitter will decrease any RF energy in the cable when you cross over to the other side of that splitter, so, you really have to treat each wallplate location as a cable section on its own, running the test from each wallplate, moving in the direction where the splitter should be.  What I'm hoping is that with the transmitter connected at each wallplate, that will give you the ability to follow the cable (in the wall) when the probe sensitivity is turned all the way up.  

 

In the room where the modem is located, connect the transmitter, and with the downstairs cable disconnected, see if you can detect that transmitter anywhere around the wallplate.  If you don't know which direction that cables arrives from at the wallplate, don't assume that it goes in the direction of the basement cable.  With the probe right at the wall, sweep all around the wallplate , moving further and further away, and see if the probe can detect the direction that the cable goes.  You may have to go up the wall as well, depending on where that cable might go.  Turn the sensitivity all the way up so that the probe beeps very loudly at the transmitter site.  Keep the sensitivity turned up and hopefully the probe beep will gradually decrease as you move away from the transmitter and keep beeping as you follow the cable path along the wall.

 

Try this at all wallplate locations to see if you have any success anywhere in the house.  Keep the basement tan cable disconnected.  For the upstairs wallplate, maybe they come straight down to the room below?  So you would have to check all around the upstair wallplates with the probe, and perhaps immediately below that location, on the wall that is just below that upstairs wallplate. 

 

If this just doesn't work, the next step would be to call in a company that has a better detection system.  This is only powered by battery, so, perhaps it takes a powered system to generate enough RF energy in the cable so that it can be detected behind the wall.  

 

Can you give this a try and let me know if you have any success at all?  I'll be very interested in your results.  I'm really hoping that the probe is sensitive enough to be able to detect the cables in the wall, but, you're going to have to run that probe right next to the wall to have any success.

 

Edit:  For the wallplate upstairs where you didn't detect anything, take the wallplate off of the wall and see if the cable is connected to the wallplate.  If its is, that implies that the other end of the cable was simply removed off of the splitter, or, it may have been cut.  I'm hoping that it was removed from the splitter.  If so, that far cable end should function as a small antenna.  You might be able to detect that end, wherever it happens to be.  In theory, those upstairs cables should arrive at a splitter upstairs, or downstairs on the main floor.  Hopefully those ends are all on the main floor.  I would test all of the  upstairs wallplates where you did not detect anything, looking to find the other end of the cable.

 

If you do manage to find a potential splitter location, buried in the wall somewhere, are your walls made out of drywall, or is your home old enough that its has lath and plaster walls?

Hi there,

 

I will try to do it if I have the time. I am also interested in where that splitter located 🙂

 

Since the schools starts and it's very busy, this might take some time.

 

Anyway, thank you so much for spending time explaining everything. You are very patient and helpful 🙂

Re: CODA-4582 MoCA 2.0 setup

@Datalink 

 

Also, I got a quick question. When testing the downstream and upstream, I noticed that, there are some particular channels, for example, channel ID 2,3,4, 28-32 etc, always have the MOST NEGATIVE values, is that normal? Is that anything I should worried?

Re: CODA-4582 MoCA 2.0 setup

Hi @alan4160 the signal levels with the two MoCA splitters might be 1 db less than the signal levels without the splitters.  In your case, it won't make any difference as both of those series of signal levels are fine.  You wouldn't see any difference between the two configurations in terms of the cable system operations, unless that lost splitter comes into the picture.  With that lost splitter in the path, a db or two here or there can make a difference in the very far end equipment.  Typically, that db or two wouldn't make a difference.

 

For the frequencies above 800 Mhz being negative, their not too bad actually.  I've seen much worse.  That due to a High Frequency roll-off that occurs in some neighbourhoods.  Some of the equipment in the neighbouhood requires replacement with higher frequency capable equipment.  That also includes cabling in some cases, such as RG-59 cabling in homes.

Re: CODA-4582 MoCA 2.0 setup

I'm also preparing to leverage MoCA and can use some guidance. My CODA-4852U had a MoCA option currently disabled. I typically leave the modem in Bridge mode but couldn't see the MoCA option until I enabled Gateway function.
My current home setup and hardware:
- I have while home PVR with 3 netboxes
- there appears to be a filter between the root line in and the trot splitter (likely added by Rogers tech for whole home PVR??)
- the root splitter is a 3way splitter (Antronix CMC2003H-A)
- both of the -7db outs go netboxes.
- the -3.5db out goes to another 2 way splitter (CMC2002H-A) which has 2 outs of -3.5db each... 1 going to the primary netbox and the other going to the modem
- I recently purchased and have started using unifi router, switch and access point devices. I'd like the modem, router and switch to go to the basement (,currently on main floor) and the access point ceiling mounted on the 2nd floor. My thinking was to leverage MoCA for the 2nd floor coax to the access point.

Amongst my questions, I'm wondering if I need to MoCA adapters or only 1 (if I enable MoCA on the modem).

Any help and guidance is greatly appreciated. Thanks in advance.

Re: CODA-4582 MoCA 2.0 setup

@rmann2020 are you using the Nextbox Home PVR capability, which uses the MoCA D-Low Band?  If not then you're better off with two adapters as they can be configured to use both MoCA D-Low and D-High band (entire D Band).  The 4582 modem is locked into the D-High band, as shown in your post, so, you would probably see faster data rates with two separate adapters.  

 

Depending on how you want to physically configure the cable network, you're going to have to replace, one, or maybe both splitters.  If you only want to run the modem cable and upstairs cable on MoCA, then you could run those on a two port splitter.  You will need a MoCA 2.0 qualified splitter as you need that higher frequency response between the two internal ports to support MoCA 2.0 frequencies.  If you're looking to run more than two adapters, then you will have to replace both splitters with a single four port splitter.  As it is now, all of the splitter ports have a -7 dB drop, no matter what port you're looking at.  

 

There is more information scattered around the forum, so, at this point I'll point you in their direction for a little reading.  Their not exactly the same situation, but, the information regarding MoCa operations is the same, no matter what you're trying to do.  As you read thru those posts, the information contained in the posts will hopefully answer some if not most of your questions.  The starting point is this post:

Would you happen to know if your house cables are RG-59 or RG-6.  I'd also pull the wallplate off of an existing wallplate with a cable port or telephone connector to determine if you had structured cabling in the house which isn't in use.  That consists of two RG-6 cables for cable/satellite, one Cat-5e for data and one Cat-3 for telephones.  If you have that cable bundle installed, you wouldn't need to use cable to ethernet adapters.
