CM1000 RNG-RSP Issues
Since the new firmware update of V3.01.02 that was pushed out to Comcast I have been receiving "RNG-RSP CCAP Commanded Power in Excess of 6db Below the Value Correstponding to the Top of the DRW" err...
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.
Just an update from my earlier post: Same issue, same firmware version with no update. I'm only typing this now because I've been having to reset my modem several times a day (at least) to have any decent throughput (I pay for 150MB) until it craps out again and takes my internet speed down to a drip-drip rate.
I would really like to see someone in an official capacity comment on this from Netgear, instead of this "community" just standing around scratching our heads and talking into a void. There is someone somewhere over in Netgear engineering who knows exactly what types of things might trigger this issue. That information, in turn, could then be used to inform Comcast techs on how to fix it. Or Netgear themselves could issues a patch that would bring back some reasonable stability to these units until further research can be done to correct it. Perhaps they could add a software option to enable/disable something that would make the modem operate more like my older Netgear modems did.
