About Stephen66

Yesterday I installed a splitter to connect to the xfinity cable TV box. Then reset the modem this morning at 7:15 or so. Cleared the log. Below are my stats and logs after six hours of the manual reboot.  I have not to my knowledge experienced a reboot that I am aware of. However since experiencing the issue for Sep 15th, I don't want to yet call it good to go.   Downstream Bonded Channels Channel Lock Status Modulation Channel ID Frequency Power SNR Correctables UnCorrectables 1 Locked QAM 256 1 453000000 Hz 2.7 dBmV 38.6 dB 22 0 2 Locked QAM 256 2 459000000 Hz 2.5 dBmV 38.6 dB 23 0 3 Locked QAM 256 3 465000000 Hz 2.2 dBmV 38.6 dB 5 0 4 Locked QAM 256 4 471000000 Hz 2.0 dBmV 37.6 dB 11 0 5 Locked QAM 256 5 477000000 Hz 2.2 dBmV 38.6 dB 12 0 6 Locked QAM 256 6 483000000 Hz 2.7 dBmV 38.6 dB 0 0 7 Locked QAM 256 7 489000000 Hz 2.9 dBmV 37.3 dB 14 0 8 Locked QAM 256 8 495000000 Hz 3.0 dBmV 38.6 dB 14 0 9 Locked QAM 256 9 519000000 Hz 2.7 dBmV 37.3 dB 1 0 10 Locked QAM 256 10 525000000 Hz 2.4 dBmV 38.6 dB 12 0 11 Locked QAM 256 11 531000000 Hz 2.0 dBmV 37.3 dB 8 0 12 Locked QAM 256 12 537000000 Hz 2.4 dBmV 38.6 dB 23 0 13 Locked QAM 256 13 543000000 Hz 3.0 dBmV 38.6 dB 8 0 14 Locked QAM 256 14 549000000 Hz 3.2 dBmV 37.6 dB 121 10 15 Locked QAM 256 15 555000000 Hz 3.7 dBmV 37.3 dB 6136 19822 16 Locked QAM 256 16 561000000 Hz 3.5 dBmV 37.6 dB 49750 46171 17 Locked QAM 256 17 567000000 Hz 3.7 dBmV 38.9 dB 60761 59021 18 Locked QAM 256 18 573000000 Hz 3.9 dBmV 37.6 dB 15965 20037 19 Locked QAM 256 19 579000000 Hz 3.7 dBmV 37.3 dB 15469 26450 20 Locked QAM 256 20 585000000 Hz 3.0 dBmV 38.6 dB 72832 109941 21 Locked QAM 256 21 591000000 Hz 2.4 dBmV 37.3 dB 10567 173 22 Locked QAM 256 22 597000000 Hz 2.2 dBmV 37.6 dB 172 0 23 Locked QAM 256 23 603000000 Hz 3.0 dBmV 37.6 dB 60 0 24 Locked QAM 256 24 609000000 Hz 3.2 dBmV 37.6 dB 272426 59980 25 Locked QAM 256 26 615000000 Hz 4.5 dBmV 38.6 dB 58347 60171 26 Locked QAM 256 27 621000000 Hz 4.6 dBmV 37.3 dB 14892 7622 27 Locked QAM 256 28 627000000 Hz 4.4 dBmV 38.6 dB 11798 11225 28 Locked QAM 256 29 633000000 Hz 3.5 dBmV 37.9 dB 14047 12642 29 Locked QAM 256 30 639000000 Hz 3.7 dBmV 37.9 dB 4195 8433 30 Locked QAM 256 31 645000000 Hz 3.7 dBmV 38.2 dB 48 2074 31 Locked QAM 256 32 651000000 Hz 4.0 dBmV 37.9 dB 18466 16078 32 Locked QAM 256 33 657000000 Hz 3.2 dBmV 38.2 dB 42740 18481 Upstream Bonded Channels Channel Lock Status US Channel Type Channel ID Symbol Rate Frequency Power 1 Locked ATDMA 17 5120 Ksym/sec 23700000 Hz 46.0 dBmV 2 Locked ATDMA 18 5120 Ksym/sec 30100000 Hz 45.0 dBmV 3 Locked ATDMA 19 5120 Ksym/sec 36500000 Hz 44.8 dBmV 4 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 0.0 dBmV 5 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 0.0 dBmV 6 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 0.0 dBmV 7 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 0.0 dBmV 8 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 0.0 dBmV   Time Priority Description Mar 26 2019 08:34:33 Warning (5) Lost MDD Timeout Mar 26 2019 08:52:15 Critical (3) No Ranging Response received - T3 time-out Mar 26 2019 08:53:54 Warning (5) Lost MDD Timeout ...

Well, I figured replacing a cable wasn't going to correct it, and I mentioned that to the tech. Normally a cable or connection issue would be more consistent, ruling out something cause interference or perhaps rain/water. However, he did take some possibilities off the table. No reboot yet, but only a matter of time. Will continue to monitor.   Interesting, the changes in dBmV between the last stats above and the stats below in a 6 hours time span. Some channels are +1 and some up to +4dBmV. Would that be normal? Would day heat to night cooling cause such an effect? Regardless, none of the levels are outside the modems operational range.   Here are the latest stats after refreshing Downstream Bonded Channels Channel Lock Status Modulation Channel ID Frequency Power SNR Correctables UnCorrectables 1 Locked QAM 256 1 453000000 Hz 7.0 dBmV 38.9 dB 16 0 2 Locked QAM 256 2 459000000 Hz 6.6 dBmV 38.6 dB 9 1 3 Locked QAM 256 3 465000000 Hz 6.5 dBmV 38.9 dB 0 0 4 Locked QAM 256 4 471000000 Hz 6.5 dBmV 38.6 dB 0 1 5 Locked QAM 256 5 477000000 Hz 6.6 dBmV 38.9 dB 14 0 6 Locked QAM 256 6 483000000 Hz 6.9 dBmV 38.9 dB 0 1 7 Locked QAM 256 7 489000000 Hz 6.9 dBmV 37.6 dB 25 0 8 Locked QAM 256 8 495000000 Hz 7.1 dBmV 38.9 dB 6 0 9 Locked QAM 256 9 519000000 Hz 7.4 dBmV 37.6 dB 5 0 10 Locked QAM 256 10 525000000 Hz 7.3 dBmV 38.6 dB 27 2 11 Locked QAM 256 11 531000000 Hz 6.8 dBmV 37.3 dB 23 32 12 Locked QAM 256 12 537000000 Hz 6.9 dBmV 38.6 dB 100 1064 13 Locked QAM 256 13 543000000 Hz 7.9 dBmV 38.6 dB 64 1188 14 Locked QAM 256 14 549000000 Hz 8.0 dBmV 37.6 dB 104 47 15 Locked QAM 256 15 555000000 Hz 8.0 dBmV 38.6 dB 364 828 16 Locked QAM 256 16 561000000 Hz 8.1 dBmV 37.6 dB 317 864 17 Locked QAM 256 17 567000000 Hz 8.9 dBmV 38.6 dB 195 937 18 Locked QAM 256 18 573000000 Hz 9.5 dBmV 37.6 dB 913 1144 19 Locked QAM 256 19 579000000 Hz 9.0 dBmV 38.6 dB 3587 1145 20 Locked QAM 256 20 585000000 Hz 8.4 dBmV 38.6 dB 208917 1309 21 Locked QAM 256 21 591000000 Hz 7.9 dBmV 37.3 dB 1582525 3190829 22 Locked QAM 256 22 597000000 Hz 8.0 dBmV 38.6 dB 249581 224994 23 Locked QAM 256 23 603000000 Hz 8.5 dBmV 37.6 dB 271584 605085 24 Locked QAM 256 24 609000000 Hz 8.5 dBmV 37.6 dB 3180617 2393870 25 Locked QAM 256 26 615000000 Hz 9.8 dBmV 38.2 dB 6066 7023 26 Locked QAM 256 27 621000000 Hz 9.5 dBmV 38.2 dB 23137 29239 27 Locked QAM 256 28 627000000 Hz 10.1 dBmV 38.9 dB 113466 53520 28 Locked QAM 256 29 633000000 Hz 10.5 dBmV 38.2 dB 456376 112380 29 Locked QAM 256 30 639000000 Hz 11.4 dBmV 37.3 dB 6291 15688 30 Locked QAM 256 31 645000000 Hz 11.8 dBmV 38.2 dB 82609 99844 31 Locked QAM 256 32 651000000 Hz 12.5 dBmV 38.2 dB 16748 5082 32 Locked QAM 256 33 657000000 Hz 12.4 dBmV 38.2 dB 14846 18192 Upstream Bonded Channels Channel Lock Status US Channel Type Channel ID Symbol Rate Frequency Power 1 Locked ATDMA 17 5120 Ksym/sec 23700000 Hz 41.5 dBmV 2 Locked ATDMA 18 5120 Ksym/sec 30100000 Hz 40.5 dBmV 3 Locked ATDMA 19 5120 Ksym/sec 36500000 Hz 40.3 dBmV 4 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 0.0 dBmV 5 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 0.0 dBmV 6 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 0.0 dBmV 7 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 0.0 dBmV 8 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 0.0 dBmV   Event log Time Priority Description Mar 20 2019 17:32:54 Warning (5) Lost MDD Timeout Mar 20 2019 18:48:53 Error (4) Service Change Response rejected - Invalid transaction ID Mar 20 2019 18:49:07 Warning (5) Lost MDD Timeout ...

Here they are EG. Note that I have not put a splitter on to the xfinity cable box yet, which would take these levels down 3.5dBmV. Rather wait and see if the latest changes make a difference.

Luckily, the tech was dispatched out within 2 hours of placing the ticket in with Comcast. That was quick. He replaced the coupler and the cable from the Comcast filter to the house with RG11. Another team will be out to place RG11 and in the ground in 3 to 7 days. He also installed a 6db attenuator to pad the dbmV downstream signal. He indicated he would contact another technician to come out and test or verify levels at the node to see if things check out there or not.   I cleared event log and everything is clean as of right now. Will know in at least 48 hours if the problem changes, persists or clears. ... View more

After another reboot. Will contact Comcast today to see I can get a tech out here to resolve the issue. Notice downstream channels 31 and 32 not connected.

I placed a splitter before the modem a few weeks ago and that made the situation worse. But I can try that again.

Another update I can't tell whether the modem rebooted and the event log stayed intact. Some of the uncorrectable errors reduced, which leads me to believe the modem did reboot. However, I am not sure exactly how the Netgear CM700 is reacting to the issues it is experiencing.
