ContributionsMost RecentMost LikesSolutionsNetgear CM1000 Critical errors in logs and constant reboots. I bought two CM1000 modems due to cox support telling me the first one was defective. The issue I had was the modem would only stay connected for 30 seconds, then reboot. Unfortunately support refused to help me beyond telling me to buy a new one as its probably defective, and if that wasn't it, to call Netgear. which I highly doubt they have anything to do with it. My previous modem is a cm700 and it at least only has a few dropped packets here and there. The log follows. 2019-09-12, 19:22:32 Notice (6) SW Download INIT - Via NMS 2019-09-12, 19:22:32 Error (4) Disruption during SW download - Power Failure 2019-09-12, 19:22:23 Warning (5) Dynamic Range Window violation 2019-09-12, 19:22:23 Warning (5) RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC=28:80:88:ac:ea:60;CMTS-MAC=00:38:df:09:4e:ad;CM-QOS=1.1;CM-VER=3.1; 2019-09-12, 19:22:23 Warning (5) Dynamic Range Window violation 2019-09-12, 19:22:23 Warning (5) RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC=28:80:88:ac:ea:60;CMTS-MAC=00:38:df:09:4e:ad;CM-QOS=1.1;CM-VER=3.1; 2019-09-12, 19:22:23 Warning (5) Dynamic Range Window violation 2019-09-12, 19:22:23 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=28:80:88:ac:ea:60;CMTS-MAC=00:38:df:09:4e:ad;CM-QOS=1.1;CM-VER=3.1; 2019-09-12, 19:22:23 Warning (5) Dynamic Range Window violation 2019-09-12, 19:22:23 Warning (5) RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC=28:80:88:ac:ea:60;CMTS-MAC=00:38:df:09:4e:ad;CM-QOS=1.1;CM-VER=3.1; 2019-09-12, 19:22:23 Warning (5) Dynamic Range Window violation 2019-09-12, 19:22:23 Warning (5) RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC=28:80:88:ac:ea:60;CMTS-MAC=00:38:df:09:4e:ad;CM-QOS=1.1;CM-VER=3.1; 2019-09-12, 19:22:23 Warning (5) Dynamic Range Window violation 2019-09-12, 19:22:23 Warning (5) RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC=28:80:88:ac:ea:60;CMTS-MAC=00:38:df:09:4e:ad;CM-QOS=1.1;CM-VER=3.1; 2019-09-12, 19:22:22 Warning (5) Dynamic Range Window violation 2019-09-12, 19:22:22 Warning (5) RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC=28:80:88:ac:ea:60;CMTS-MAC=00:38:df:09:4e:ad;CM-QOS=1.1;CM-VER=3.1; 2019-09-12, 19:22:21 Warning (5) Dynamic Range Window violation 2019-09-12, 19:22:21 Warning (5) RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC=28:80:88:ac:ea:60;CMTS-MAC=00:38:df:09:4e:ad;CM-QOS=1.1;CM-VER=3.1; 2019-09-12, 19:22:21 Warning (5) Dynamic Range Window violation 2019-09-12, 19:22:21 Warning (5) RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;CM-MAC=28:80:88:ac:ea:60;CMTS-MAC=00:38:df:09:4e:ad;CM-QOS=1.1;CM-VER=3.1; 2019-09-12, 19:22:16 Notice (6) DS profile assignment change.
