@MorbidDesire, thats a pretty interesting screen capture. If I wasn't suspicious about the Casa CMTS itself, I would have said that the image indicates a severe cable issue. Single channel downstream and single channel upstream with the modem running at its maximum output power level on the upstream channel. Are these fast disconnects long enough that you can get in touch with Tech Support before the modem returns back to normal operation? The real question that I have is what is the CMTS doing at this time? Only Tech Support could answer that one.
@MorbidDesire, is that a Rogers cable amplifier, or something that you have installed yourself? Normally you should not need an amplifier at all. The output at the neighborhood node is balanced by the cable losses between the node and your modem. The signal levels should arrive at the home somewhere around 0 to 3 dBmV, perhaps a little higher depending on the distance to the node. If that was an older Rogers amp, the splitter would make sense. The old amps amplify everything and cause packet loss on the internet modem, so, these days the Rogers Techs will remove those amps and replace them, if necessary, with a new generation of amplifier. The new amps have a passive path thru them for VOIP applications, which is also used for the internet modem, so, no amplification on the internet path.
So, the splitter and connection to the modem was probably in place to prevent any packet loss on the modem's cable line. The splitter itself would cause a 3.5 or 7 db drop in downstream levels, depending on what port the modem was connected to. The upstream would also increase by the same amount.
It sounds as if you have removed the bypass around the amp. While that will definitely change the signal levels, you might not be doing yourself any favours. If that amplifier is something that you installed yourself, your best course of action would be to remove the amp completely, then have a look at the signal levels on the modem, and consider the results on any cable tv modems that you have running. If there are any issues, then call tech support to check the levels, with the aim of possibly getting a tech out to the home to inspect and replace any cabling and connectors that require replacing.
If a tech found a homeowner installed amp, he or she would remove the amp and charge for the visit as the problems are due to homeowner installed equipment. If the cabling and connectors are in original installation condition, then the tech visit should not cost anything.
My guess is that if the other connections to the splitter are no longer required, there is a good chance that the amplifier is no longer needed as well. Depending on how many cables are installed on the amp, you might simply be able to connect them to the splitter and pull the amp out of the circuit. It just depends on the number of ports on the amp and the splitter and the number of cables currently in use on the amplifier.
@MorbidDesire, assuming that I've found the right amp, as pictured here:
have a look at your amp and look for the port that is marked with a telephone symbol or text indicating "VOIP". That is the port that the internet cable should be on, as its a passive path thru the amp, without any amplification or potential for packet loss.
@Wolftrap1, can you:
1. log into your modem and check the Software Version(firmware) that is shown on the STATUS page. Please let me know what that is. It should be 4.5.8.22 by now.
2. Navigate to the STATUS .... DOCSIS WAN page, copy the downstream and upstream tables and paste them into a post. The copy and paste process will paste in the text contents of the tables, so a screen capture won't be necessary. Those are the cable signal levels and signal to noise ratios which may be of interest at this point.
