@herrshaun can you delete the CM-MAC data please. That should be posted in an open forum.
Looking at the data, yup, it looks like a disconnect, but, I can't ascertain any reason for the disconnect. Depending you where you are located, and what the modem is set for in terms of time zone, that might be a 2 or 3 am disconnect at the neighbourhood node, or possibly a firmware update. If it was a firmware update, you should see the download indicated in the log just before the disconnect.
Fwiw, over the last week, I've seen disconnects occur at my neighbourhood node, usually just after 2 or 3 am local time. There's nothing evident in the log, but, there is most definitely a disconnect as both the internet and home phone were dead. Rogers has been changing some aspects of its network, with no pubic announcements of what its doing, so, the disconnect could be part of that, or it could be just normal maintenance that occurred.
@herrshaun its really difficult to know if the disconnect is maintenance related or if its a random disconnect. The timing leads me to think it was maintenance related, but I could definitely be wrong. The crystal ball is in the shop for overhaul 🙂
When you have time, and the patience to do it, can you log into the modem, navigate to the STATUS .... DOCSIS WAN tab and copy the entire table under the "Downstream Overview" line. Select or highlight the whole table, all the way down to the bottom right hand corner of the bottom OFDM/OFDMA section .... right click, Copy. Then in a new post .... right click, Paste. That should paste in the whole table. Maybe the signal data might show if there's a problem on the go.
@blazevicm the problem with your signal levels is that the downstream levels are too high. The normal signal level for the DOCSIS 3.0 channels (1 to 32) should be close to 0 dBmV. Historically from what we've seen in the various posts, once your above a +6 / 7 dBmV level, or below a -6 / 7 dBmV level, you start to see problems of some type. Thats despite the allowable range of + / - 15 dBmV for the downstream levels. Rogers typically won't do anything unless the signal levels are above + 10 dBmV or below - 10 dBmV, so, looking at your signal levels, you appear to qualify for a tech visit.
The other strange issue is that the upstream DOCSIS 3.0 signal levels are above the normal 30 to 32 dBmV range. Yours are sitting in a 33.750 to 42.750 dBmV range.
So, for some reason, you have very high downstream levels and higher than normal upstream levels. That's the opposite of what usually happens. Usually the downstream drops while the upstream climbs towards a failure point at 51 dBmV.
Normally to resolve this the tech could simply install a signal attenuator on the inbound line to the modem. That would drop the downstream level but it also pushes up the upstream towards the failure point at 51 dBmV. Because the upstream levels range up to 42.750 dBmV, that leaves the tech very little room, in terms of the upstream power levels. The tech has to address the high downstream levels without driving up the upstream levels to or beyond the failure point.
Ok, to that end, a couple of questions:
1. are you in a house or condo, apartment , highrise type of building?
2. Can you take a look at the inbound cable to your home. Do you happen to have a powered amplifier installed. You would recognize it as it would be the only powered device connected to the inbound cable.
3. Are you running more than one Rogers service, like Internet, Cable TV, Home Phone? If so, then you would either have a passive splitter or a powered amplifier installed. Can you have a look at that inbound cable and if there is a powered amp or a passive splitter, can you grab the model number off of the front of it and post it. It should be an Antronix amp or splitter.
Hope this helps. I think the tech will have a tough time to do anything. It depends to a degree on what type of building you're in, house, or larger condo / apartment type of building.
Edit: The 4582 modem uses the Downstream OFDM channel for its downstream data. It doesn't use the upper DOCSIS 3.0 channels unless the OFDM channel fails to hold a minimum of 64 QAM within that OFDM channel. The problem here is that the channel data isn't presented to the user, so, there is no way for me or anyone else, looking at the user interface, to determine the health of that channel. Tech support has access to that data, and I suspect that the field techs should as well. There is a good chance that the OFDM channel is running normally but the only way to determine that would be to ask tech support for the OFDM channel QAM number. It should be 1024 if the OFDM channel signal levels and signal to noise ratios are within acceptable levels. Anything less than 1024 would indicate that there is some problem within the OFDM channel frequency range which in your case runs from 275.6 Mhz up to 467.6 Mhz. That would require a field tech to check the external cabling and connectors, as a start.
The other issue is that if your signal levels were dropped to an acceptable level, the question to be asked is, is there a problem with the external cable and its connectors. They only last for so long before they require replacement. One sign of degradation of one or the other is short disconnects that don't show up in the signal table. If you were to run a ping test over ethernet to the Rogers DNS at 64.71.255.204, you might see timeouts occurring. At the present time that might be due to the high signal levels, or it might be due to an external cable/connector issue or perhaps a combination of both.
We'll see what happens with the tech visit. Please ask the tech exactly what was done and post that info.
