A few months ago, I changed from the Triple Play to Internet only service. I also went from 105 speed to 250. Ever since then, I've been having disconnect problems. This has happened with multiple modems and routers. Current Setup is Arris SB6183 and Netgear AC1750 R6400
2 Techs have been to the house so far. Any guidance on how to find the issue?
The statuses listed show the connection state of the cable modem. They are used by your service provider to evaluate the operation of the cable modem.
The table below contains the log of events that the SB6183 has detected. This log can be important to the service provider to help diagnose and correct problems, if any should occur.
Even though the signal stats looked o/k at that snapshot in time, the error log entries confirm that something is going on. Perhaps there is noise ingress into the line(s) somewhere.
There are other signal stat figures that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.
I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. They can check the CMTS (Cable Modem Termination System) for any real time degradation and / or error reports, see your node / cable plant and modem health, and see whether or not everything is in the green zone. They can also see a history plot for the modem and poll for those upstream receive signal stats.
I couldn't agree with you more, EG! Thanks for letting us know about this!
cdziedzic, appreciate you taking the time to post your logs and let us know about your service issues on the forums. Thanks for allowing us an opportunity to resolve! Let's check your historical plots as well as your signal levels at and outside the premise to get an idea of what might be going on in your area. Please send me a private message with your full name for help!
