What are good signal levels

Hi everyone!

 

I'm currently on the Hybrid Fibre 150 package and I'm using the Hitron CGN3ROG modem/router. I was wondering what are good downstream and upstream signal ratios? If someone could provide a range that would be great. I'm also wondering what were the best signals you have seen coming from the router? Here is a screen shot of my current signals:

Assume the Upstream power levels of 52-53 are out of spec and I should be calling Rogers?

@wp519, yes, call tech support.  Ask the CSR to run a signal check on the modem.  That check should fail automatically due to the high upstream levels which are above the max level.  The CSR should then arrange for a tech visit to determine and correct the issue. 

 

The downstream levels aren't too bad, dropping down into the -3/-4 dBmV range, but thats ok, and your downstream signal to noise ratios are ok.

My docsis results are below,  I saw in other forums that they should range from -10 to 10 so I had them do a signal check.   Tech came out and installed an amplifier on the incoming cable line before the 4 way splitter which brought levels up to -1 to -3 but the signal to noise was fine on the first 2 channels and the last 2 all the middle ones were in the 4 range and then internet cacked out within 30 mins of tech leaving.  I took the amplifier back out so back to the levels below.   Current setup is a 4 way splitter coming into house going to 2 tv's, home phone and a line to a 2way splitter that feeds tv and internet.  What is the best layout if I want to move things around for a better signal to the modem?

@Ed15 Removing the amplifier has actually made your downstream signal strength worse. In this case, b/c you don't have an amplifier your signal levels are out of spec; they're really weak. I HIGHLY suggest to re-install the amplifier which will increase your downstream signal strength. The tech installed the amplifier because he noticed that your signal levels are weak. Once you install the amplifier back, reboot the modem and your signal levels should be fine. 

 

What you could also do to ensure good signal strength is to replace old coaxial cables with new ones that have shielding against interference. You can buy high-quality coaxial cables from Lowe's or Home Depot. Because everything is connected together, a cheap coaxial cable can actually cause interference issues and lower your signal strength.

Nope, the amplifier that Rogers uses does not have an amplified port for the Internet cable.  Its a straight thru port with a -3.5 loss.  This is done so that the intenet data does not suffer any packet loss due to the amplifier.  The solution here is to address the low signal levels arriving from the external cable.  Adding an amplifier only amplifies an already poor signal. 

 

Call tech support and ask the CSR to run a signal check on the modem.  That check will fail automatically and the CRS will arrange for a tech to visit your home again.  Indicate that you have already had a tech out to your home, I'm assuming it was a contract tech, and ask for a senior tech, which is a Rogers tech.  Ask the CSR to check your neighbors modems as well for the signal levels.  If they are low, and I'm assuming that they might be, that points to a problem further upstream, which might require a maintenance crew instead of a tech. Hopefully this time around, you can get the right person or staff working on the problem.

 

Looking at your signal levels, it appears that you have an original CODA-4582.  You're missing several channels which indicates an EMI issue between the 2.4 Ghz and the Docsis tuner.  You will need to swap your modem for the same model modem but, the new batch has a black dot on the outside of the packing box and near the power cord plug in point of the modem.  That modem has additional shielding to prevent that EMI. 

 

In terms of the best configuration for the cabling, the very best, if the signal levels can't be brought up is to install the amplifier and run the internet feed cable off of the non-amplified port.  Ideally that cable would not be split any further, but, even it was, the total loss from the street ot the modem would be -7 dB instead of -10/11 dB.  That alone might be enough to make a difference.  The remaining devices would be fed from the amplified ports of the amplifier.  On the amplifier itself, there should be one port marked VOIP, which is straight thru, non-amplified.  That is the port that is used for the internet as well.

Tech told me the incoming signal is good,  I assuem it is low as it looses 7.5 at the first splitter then 3.5 at the 2nd.  He tried amping everything with an amp with only 1 output.

The amp only has one input port and one output port?  Can you read my additional comments above regarding the modem and cable configuration.  You are correct about the splitter losses.

Re: What are good signal levels

It's a black dot modem but from before the posts that said they were retesting the black dot ones,  I never noticed the missing channels before.

Re: What are good signal levels

Do I put the amp back in before calling for a signal check.?

 

This is the amp he installed,  

MRA1-15/ACP one output micro amplifier with power supply

there was no existing wiring to the location the computer/modem sit at so they put a 2way splitter at the tv and ran the rg6 along the back of a sofa and shelf to get to my computer desk.  The new route was street -> amp > 4way -> 2way -> modem.   I can fish a rg6 to the desk pretty easy and move the 2way to the first step.

Re: What are good signal levels

gp-se
I'm an advisor

Rogers wont fish any wires, so if you can fish a wire from the computer where to modem is to the utility room where the cable comes in that would be good. You don't need to put the connectors on, the Rogers tech can do that for you, but make sure you use a high quality RG-6 cable. Ultimately You want the Setup like this:

 

Cable Drop ->

2 Way Splitter: Output 1: Cable Modem, Output 2: to a 3 way splitter for your other devices. 

 

 

Re: What are good signal levels

Or .... do the following after fishing another RG-6 cable to the desk:

 

Cable Drop -> 4 port amp with passive VOIP port ->  Devices

 

Output 1 (Passive Pass Through Voip port):  Internet Modem

Output 2:Home phone ?

Output 3:TV

Output 4:TV

 

There are amplifiers with a passive VOIP port that have 8 output ports, so, if you need to connect to more devices that is possible.  The first step in all of this is to run another RG-6 cable.   After the cable is run, you should be able to call Rogers to have a tech replace the modem and amp and add connectors onto the new RG-6 run.  The problem,  as usual, is to provide a dedicated cable to the internet modem with the least amount of signal drop as possible and at the same time service all of the other modems.  With a high enough signal level at the very start, this can easily be done with a splitter.  But, when you start at around 0 dBmV or lower, then you need to look at an amplifier with the passive port, or, the tech has to determine why the signal level is too low to start with and get that back up to where it should be.  Sometimes that requires a maintenance crew.

These are my signal levels. Are they okay? It seems the downstream SnR isnt very good? We do have a screw on -5 adjustment piece on it. Having issues with upstream packet loss while gaming, constant 2-5% loss causing major problems.

 I recall it used to be the following:

 

•Receive/Downstream: -15dbmV to +15dbmV

•Transmit/Upstream: 30dbmV to 53dbmV

•Signal to Noise Ratio(SNR): 33dB or Greater

 

If I wanted to improve my signal, what level should I aim for? 

 

Thanks

Re: What are good signal levels

generally, you want it as close to 0 as possible.. with a +/- of 10.

While your highest and lowest are not that too far off..

 

I think the bigger issue may be how/why its jumping around so much.
Generally you will see it more gradual in my experience.. but you have things like a jump from 1.3 right to 5.3 on adjacent channels

Re: What are good signal levels

Generally it should be within this range for DOCSIS 3.0: 

 

  • Downstream Signal Strength Range: -10 to +10 dBmV
  • Upstream Signal Strength Range: 35 to 52 dBmV

 

With regards to DOCSIS 3.1:

 

  • OFDM PLC Power: -9 to +10 dBmV
  • OFDMA uplink values:
  • 29 to 46 dBmV for channels with a bandwidth of 6400000
    32 to 49 dBmV for the channel with a bandwidth of 3200000

 

@RogersDave are these dBmV values correct for OFDMA? Just making sure Smiley Happy

Re: What are good signal levels

At this point, the DOCSIS 3.0 downstream levels really don't mean very much, other than a possible indicator of the level for the DOCSIS 3.1 channel.  The modem is running on DOCSIS 3.1 downstream, so the 3.0 channels are not used.  The OFDM data, frequency and signal level are not correct as displayed in the DOCSIS WAN tab, so, at this point, all you can do is call tech support and ask the CSR what the signal level is for the 3.1 downstream channel and if it is within spec.  The upstream DOCSIS 3.0 signal levels are controlled by the CMTS, so the modem transmits the required output levels as commanded by the CMTS so that the upstream channels arrive at the CMTS at 0 dBmV and greater that 25 dB (?) signal to noise ratio.  That signal to noise number might be exact, don't remember if thats the exact number at the present time.  The upstream levels are higher than I would expect to see, so that might be an indicator of a noise issue between the modem and the CMTS.  That is something you could ask tech support about as well, whether the noise at the modem is in a normal range or if its elevated, and if it is elevated, is it just your cable, or that of your neighbors as well, which would indicate a wider area problem.  

 

If you're experiencing slow data rates with DOCSIS 3.1 running, you're not the only one.  There have been a few complaints regarding modem performance with 3.1 running.  If this is the case, my first suspicion would be on upstream congestion at the CMTS.  If you look at the last pingplotter post below by @Nadernt, you can see the increased response times from the CMTS in the evening.  They peak out around 50 ms in the afternoon / very early evening, and drop down to somewhere around 20 ms or below in the very early morning.  That might be resolved when DOCSIS 3.1 upstream makes its appearance later this year, and, it might also indicate that some work is required to resolve the performance of the CMTS in the evening hours.  That is something that @RogersDave would have to pass along to the engineering staff responsible for the CMTS equipment.

Re: What are good signal levels

Good evening, 

 

I'm looking to disable the SIP ALG setting on my router. Can you provide me with instructions? Thanks. 

Re: What are good signal levels

Are you using the Rogers Modem/Gateway? if so which model are you running, the White CODA or the Black Rocket AC? 

 

I believe with the CODA the user can turn SIP ALG off/on, on the older Rocket Modem you need to call into tech support and they can do it over the phone.

I had a cable cut in my area and after 2 days it was up and running.  I had a look at my signal levels and they look really weird with QAM 64 channels.

 

Anyone seen this before?
