@Webslinger that shouldn't happen. Call tech support, ask the CSR to run a signal check on the modem which should probably fail. Let the CSR know what your experiencing with the data rates. Assuming that the signal check fails as I suspect, the next conversation item should be to arrange a tech visit to resolve the problem.
@arnym21, your downstream signal levels are high. They should be centered at 0 dBmV. If you called tech support and asked the CSR to run a signal check, that check would probably fail and as a result, a tech would probably install an attenuator to drop those signal levels back to 0 dBmV. That would result in the upstream levels going up if the attenuator was installed.
Personal opinion, if you're not having any issues, I'd probably leave it for now. Those levels are high, but, their also irrelevant as the modem is running DOCSIS 3.1 on the downstream. So, if you're not seeing any slow data rate issues, I'd leave it alone.
As for the MoCA interface, that is now built into the firmware and available. I think that started to show up in version .30 or .31, don't remember exactly.
Edit: Are you in a house or apartment/condo/highrise where its typical to see higher signal levels?
The splitter and attenutator are two completely separate pieces of hardware. You can have both in operation at the same time. If you had other cable modems, ie: cable tv box, Rogers Home Phone, depending on the signal level for the cable tv box, a tech might install the attenuator where the cable enters your home. He or she could also just install that on the back of the modem. It depends on what the signal level ranges are for the various modems.
The problem with high signal levels, in any device is that they lead to signal distortion and signal clipping, which cuts the dynamic range of a signal. That goes for any device, not just cable modems. The DOCSIS signal ranges are actually larger, I believe they run from +15 to -15 dBmV, ideally centered at 0 dBmV. Any changes in the signal to noise ratios will depend on where the attenuator is installed and where the noise source is located. If you drop the signal level and then subject the cable to some external noise source prior to the signal arrival at its destination, then yes, the SNR ratio will drop. If the attenuator is installed at the modem for example, then you have a mixture of signal and noise, and then everything drops when the attenuator is installed. So, as they say, location, location, location. It does matter.
Your modem is running DOCSIS 3.1 on the downstream. That can be seen by the one active channel in the OFDM downstream channel data, which is the DOCSIS 3.1 channel. By now, all of Rogers network is probably running both DOCSIS 3.1 on the downstream side, and IPV6.
Your getting 250/30 at the present time. What internet plan are you actually signed up for? That's important to know in order to determine if the modem is running at the plan speeds or if its running slow?
As mentioned above, its Ignite Gigabit sub, otherwise Rogers wouldn't give this modem to begin with. 
For tests, its just hooked by supplied Cat6 cable direct to a PC 1 Gig ethernet adapter (I know its a security threat), resets & reboots of everything won't fix the speed. The adapter does quite well on LAN speed tests, so its the modem or line issues.
Actually, as long as you're running an unlimited account, you're eligible for that modem. So, one could run 100 or 250 Mbs plans and run that modem.
Ok, so, first thing I would do is request the trial firmware. That shouldn't be necessary, but, there have been changes to the firmware to improve the OFDM lock.
Next I would call tech support and ask the CSR to run a signal check on the modem and see what turns up. Explain the problems that you are seeing in terms of data rates and with any other device, cable tv box and/or home phone. That may or may not lead to a tech visit although I suspect that it will. My personal opinion at this point would an issue with the buildings Multiple Dwelling Unit (MDU). That supplies data services to all of the modems in the building. Its possible that the MDU that you are connected to has a technical fault, and, its possible that there might be more than one MDU in the building, so, perhaps it might be possible for a tech to switch your cable feed to another MDU. All speculation on my part.
To request the trial firmware follow this link @CommunityHelps to navigate to the @CommunityHelps page when you are signed into the forum. On the right hand side of the page is a link titled "Send this user a private message". Use that link to navigate to the next message composition page. It will already be addressed.
1. Fill in the title with CODA-4582 Trial Firmware Request.
2. In the text area, include your request, including the modem MAC address and Serial number. The modem MAC address and serial number can be found on the sticker at the back of the modem, or copied from the data located in the Status page of the modem when you are logged into the modem.
Send that info to @CommunityHelps and you should see a reply later today or tomorrow
When you're logged into the forum, watch for a number overlaying your avatar at the upper right hand corner. Follow the avatar link down to the message inbox to acknowledge the waiver that is required for the trial firmware. When that is acknowledged, you should see the firmware loaded later in the day or the next day. When you know that the firmware has been loaded, reboot or restart the modem. Don't run a factory reset as that will return the modem back to the latest production firmware that is used across the network for that modem.
The MDU is normally located in a utility room in the basement. If you are on a Cable Modem Termination System, that is located outside. Large multi-dwelling buildings typically have one or more MDUs, but, that is not cast in concrete. You could be connected to an external CMTS, but, the modem wouldn't know the difference.
There could be a couple of issues here:
1. Some customers experience slow data rates with the 4582. Its not typical, but, its not unusual either.
2. There could also be a problem with the MDU/CMTS. The MDUs are pretty reliable,but, every once in a while we see residents in large buildings have issues due to them. Its pretty rare, and its a pain to resolve. First step is to resolve any signal issues, load the trial firmware and go from there.
I suspect that all CMTS equipment is copper cable to the home on one side, fiber on the other side. The same might be said for the MDUs, but, don't quote me on that one. I suspect that for new highrise/condo/townhome, its fibre on one side, copper on the other. That might be the same case for older buildings as well, just depends on the size of the building which in turn dictates the data requirements and from there any requirement for fibre feed.
