Hello s1lva166, Welcome to Rogers Community Forums!
Your modem is receiving good signal.
Generally speaking the signal should be for DownStream between - 10 dBmV to + 10 dBmV . Ideally at 0dBmV and SNR 36~40 dB range. For CGN3 you should have 20 channels bonded. And UpStream is normally 36~51 dBmV and with 3 Channels bonded.
Hope the above info is helpful

Your signal levels are fine for now. They are probably close to where mine are and I run the 250 Mb/s down, 20 up plan. Are you having any problems with th modem or your internet service?

Good catch. You need to call tech support, with the aim of getting a tech out to your home to check the external cabling and connectors. Your downstream power levels are near or at the bottom of the Docsis signal level range. They should all read 0 dBmV ideally. The signal to noise ratios are down slightly as well. While it is possible to run a modem at or below even your levels, you need to have really good signal to noise ratios to get away with it. I suspect that you might see some problems given the combination of low signal levels and low signal to noise ratios. The upstream levels are all elevated as well. Normally they are in a 36 to 40 dBmV range.
Those levels will not change when you run either Gateway or Bridge mode as they are the result of the condition of the cabling, connectors, and splitter losses that result from spitting the incoming cable to service more than one device. The external cabling and connectors don't last forever and every once in a while a tech visit is required to replace them. That is a very normal occurrence although it usually takes several years until the cable deteriorates to a point where it requires attention.
Your downstream signal levels are all low, averaging -8.69 dbmV, where they should all be up around 0 dBmV. Your downstream signal to noise ratios are also low, averaging 34.17. They should all be in a range of 36 to 40 dB. Your upstream signal levels are ok, which is a little strange. Normally as the downstream signal levels drop, indicating a cable or connector problem, the modem pushes the upstream output levels up to maintain communications with the Cable Modem Termination System, so the disparity between the two is unusual.
Call Tech support and ask them to run a signal check on the modem. I think the cutt-off point where they will dispatch a tech is - 10 dBmV and below. But, if you are seeing low data rates, coupled with the low signal levels, there shouldn't be any hesitation to send a tech. If you are seeing low data rates, or other issues such as pixelating on tv or breaking audio, if you also have Rogers Cable TV, make sure that the CSR understands that and acknowledges the problems.
As for your neighbor, there should be a local tap within sight of your home, usually a small green box, about waist high if you have underground cabling to your home. That connects to the neighborhood node and also to about 4 homes, including yours. Each home has an independent connection point at that tap.
Here is what the Cable TV / Internet distribution system looks like:

Please let me know how the conversation with the CSR turns out.

That signal level is not that bad generally.
LIKELY the speed issues are not necessarily due to signal though 😞
That modem is quite old.
Its only a DOCSIS 2.0 modem. That it only has 1 channel on it.
When many people get on.. its like a 1 lane road.. it gets really crouded and slows down.
As time has gone on, the newer modems are 4, 8 and now 20+ channel modems. Its like adding that many more lanes to the road.
You might want to look into some of the more current plans
Not knwoing what plan you are on now, its hard to say what is best.
But with many of the plans now, the modem rental can be included.. and often are the same prices as the older grandfathered plan which you likley would be on, and faster period..

Power Level Check; 500d, 20up
How are my power levels looking for 500 download and 20 upload on the CGN3ACSMR in Scarborough. The tech who installed my service mentioned something about the green box in the neighbours lawn needing some "things"? and that he would infrom Rogers about it.

WHOA.. yeah that could cause a big chunk of problems.
Optimaly, you should be close to 0dbm with a 'tollerance' of +/- 10.
Your WAY low.. and could likely be a cause of the problem.
Now, now knowing exactly what the tech did..
If the signal at the street is OK.. than its something between the box and your house that needs to be fixed.
But if its a signal at the BOX.. then its something that needs to be escalated to MAINTENANCE to look at.
Really this sucks then! I am located in the M1V area code of North Scarborough. So my signal levels are way low? The tech just mentioned casually that the green box buried in the neighbours lawn needs some "work" and that he'll mention it to Rogers.
I know there was a major outage a week ago? In Scarborough..
And it looks like they are doing the IPv6 conversions there now, etc..
BUt all that being done, shouldnt effect the signal in general.. I would hope.
its more than just a MENTION that should be done.
I would call back in and complain that your signal levels are real low.. and have them send out another tech.
That tech should check all the levels at each point. Start at the box.. if ok, move to where it connects outside the house.. etc.. till the find the issue..
IF its at the street.. its more than a MENTION that needs to be done, it needs to be escalated.
Yup, call tech support and ask the CSR to run a signal check on your modem. Assuming that they fail (I think they should), you should see a tech at your home fairly soon. Explain to the CSR if you have problems with any other equipment like cable set top boxes or home phone which can also be an issue due to the signal levels. If you have any outages on any of those, call tech support while the outage is in progress. That's the best time to call as it really provides proof that there is a problem, and it might be possible to determine where the problem is, either with your cable, the local tap (green box) or perhaps with the line from the tap back to the neighborhood node.

Hello, @bobbydigital
Thank you for your post, I can help with your request. As you are already aware, addressing the issue involves in accessing your account. Please send us a private message at @CommunityHelps when you are online. Our private messaging system is explained in this blog.
Cheers,
RogersMoin
@CommunityHelps, etc may be able to give you a hand, at least checking/confirming the levels you are receiving at the modem level.
They could possibly arrage a tech to come out as well to check things..
But in the end, its an on site issue that usually has to be fixed by a tech.
