CM1000 RNG-RSP Issues

I'm having the exact same issue. My new CM1000 modem is logging dozens of the following message triplets per day and a simple ping shows that I'm dropping lots of packets because of it, which obviously is messing up my throughput and general internet usability (MAC value intentionally masked):

RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC=xx:xx:xx:xx:xx:xx;CMTS-MAC=xx:xx:xx:xx:xx:xx;CM-QOS=1.1;CM-VER=3.1;

RNG-RSP CCAP Commanded Power Exceeds Value for Pmax;CM-MAC=xx:xx:xx:xx:xx:xx;CMTS-MAC=xx:xx:xx:xx:xx:xx;CM-QOS=1.1;CM-VER=3.1;

Dynamic Range Window violation

I also have Comcast/Xfinity (West Palm Beach, FL area) and have been frustrated with this. The closest info I've been able to find is some other forum where someone posted a similar problem and stated that that after some advanced troubleshooting, they eventually determined it was an issue with the software running on the box on the pole, and had nothing to do with his wiring to or within the home.

So I'm not sure if that issue is related, or if there is a mismatch between the software installed on the external hardware vs the software being pushed to these new consumer modems, but I can tell you its frustrating. I pay for 150MB and I just ran a speed test and it returned a fraction of 1MB download speed. So once again I am rebooting everything to see if that will temporarily "heal" the issue -- until another hour or two where it happens again.
