Dynamic Range Window violation and "RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW

So I have a Arris SB8200, and it seems this kinda thing always happens this time of year. The drop line has been replaced twice in 3 years. Which leads me to believe it's something at the plant or not too far down the road as the configuration of our home network including the router and modem have been the same and have not moved since the tech installed and provisioned them. Doing this fixes it for a while and then it all goes out of whack, usually because the tech files a report to have a plant mechanic come out and look at everything and they fiddle with the node at the end of the street and that fixes it.

When I see power levels this high

And log files that look like this:

It's kinda concerning that this is a repeat thing and that the logs are showing it's repeating over and over.

  • We may need to have a technician back out to investigate. I do see where a maintenance technician was out back in January and they had to replace some parts related to an amplifier. We cannot say for sure if it is the same type of issue or not. A field technician would need to diagnose the signal to the home first and if needed would forward a request to maintenance with their findings at that point. If you would like us to setup a service call, you can email us at with your service address and a link to this thread.
