Here's the route trace from PoE to office: PoE MoCA Filter (Holland B00DC8IEE6) VoIP Amp and MoCA splitter, powered and grounded (Commscope CSMAPDU9VPI) - 6 alt paths connected, 1 used: media center MoCA adapter. RG6/U, ~30ft 2-way splitter (Holland GHS-2Pro-M) - 1 alt path connected, 0 unused RG6/U, ~40ft 3-way splitter (Ideal 85-333) - 2 alt paths connected, 0 used RG6/U, ~10ft RG6 keystone jack (VCE 4335095229) RG6/U, ~3ft 2-way splitter (GE 33526) - alt path used: MoCA adapter RG6/U, ~1ft Modem (Netgear CM1150V) At the point of entry I am getting <50% of the advertised upload speed at best. That's the same result I'm getting when the modem is connected in my office. Do you not agree, then, that the root cause of the slow upload speed is independent of anything to do with my property? I'd rather divert my attention to the root cause of the immediate problem before improving my home network. ... View more

Here are the results of being attached directly to the incoming coax line for the house.     Per our discussions: Downstream Power Levels: -8dBmV to  +10dBmV Office: Currently too low at -11.4 to -9.0 PoE: On the high side. 7 to 10.1 Downstream Signal to Noise Ratio (SNR):  >35dB Office: fine. PoE: fine. 40.9 to 41.6 dB Upstream Power Level:  +25dBmV to +50dBmV Office: Too high, +55.5 PoE: fine. 40.5 dBmV.   Notably, I ran a speed test connected to the modem and had the same results as I have in the office. 360 down, ~10 up. Do you think this is sufficient for Comcast to investigate the matter without charging me?   ... View more

Thank you for your insight! I really appreciate it. I think I'll move the gateway to the first splitter in the basement, disconnect everything else, and check the singal levels there before calling Comcast - just to mitigate the risk of being charged for the visit.   Per the link you sent, I'm targeting these levels, correct? Downstream Power Levels: -8dBmV to  +10dBmV (Currently too low at -11.4 to -9.0) Downstream Signal to Noise Ratio (SNR):  >35dB  (Currently fine) Upstream Power Level:  +25dBmV to +54dBmV (Currently too high at +55.5) Upstream Signal to Noise Ratio (uSNR): >31dB   (Currently unknown?) Upstream Receive Power: -2dBmV to +2dBmV (Currently unknown?) ... View more

Thank you for that information, Bruce. I noticed that when I posted, but had to leave. Now it appears to be working. I will start reading through the troubleshooting link you you sent.   Post your modem’s error logs.  See below. [REDACTED] = CM1150V [REDACTED_2] = Local Comcast Post the make and model of your modem/gateway. Netgear CM1150V Post the make and model of your router if you have one. Issue resides when connected directly to the modem, even after a fresh restart. Let us know if you contacted Comcast or had a tech visit. Not yet. Let us know what the lights on your modem are doing when you are having problems. Power, Up link, Down link, WWW, both phone line lights are solid green. LAN light flickers green, as usual.   Error Logs "Event Logs" per Netgear Genie interface: Time Priority Description Thu Dec 05 14:53:43 2019 Warning (5) Dynamic Range Window violation Thu Dec 05 14:53:43 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Thu Dec 05 14:45:44 2019 Warning (5) Dynamic Range Window violation Thu Dec 05 14:45:44 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Thu Dec 05 12:46:54 2019 Warning (5) Dynamic Range Window violation Thu Dec 05 12:46:54 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Thu Dec 05 10:13:07 2019 Warning (5) Dynamic Range Window violation Thu Dec 05 10:13:07 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Thu Dec 05 09:42:50 2019 Warning (5) Dynamic Range Window violation Thu Dec 05 09:42:50 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Thu Dec 05 09:42:50 2019 Warning (5) Dynamic Range Window violation Thu Dec 05 09:42:50 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Thu Dec 05 08:53:14 2019 Warning (5) Dynamic Range Window violation Thu Dec 05 08:53:14 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Thu Dec 05 08:15:18 2019 Warning (5) Dynamic Range Window violation Thu Dec 05 08:15:18 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Thu Dec 05 06:12:28 2019 Warning (5) Dynamic Range Window violation Thu Dec 05 06:12:28 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Thu Dec 05 02:12:09 2019 Warning (5) Dynamic Range Window violation Thu Dec 05 02:12:09 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Wed Dec 04 23:02:45 2019 Warning (5) Dynamic Range Window violation Wed Dec 04 23:02:45 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Wed Dec 04 22:17:49 2019 Warning (5) Dynamic Range Window violation Wed Dec 04 22:17:49 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Wed Dec 04 09:53:14 2019 Warning (5) Dynamic Range Window violation Wed Dec 04 09:53:14 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Wed Dec 04 06:57:29 2019 Warning (5) Dynamic Range Window violation Wed Dec 04 06:57:29 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Tue Dec 03 22:05:25 2019 Critical (3) SYNC Timing Synchronization failure - Loss of Sync;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Tue Dec 03 21:53:21 2019 Warning (5) Dynamic Range Window violation Tue Dec 03 21:53:21 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Tue Dec 03 21:53:21 2019 Warning (5) Dynamic Range Window violation Tue Dec 03 21:53:21 2019 Warning (5) RNG-RSP CCAP Commanded Power Exceeds Value Corresponding to the Top of the DRW;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Tue Dec 03 21:53:07 2019 Notice (6) TLV-11 - unrecognized OID;CM-MAC=[REDACTED];CMTS-MAC=[REDACTED_2];CM-QOS=1.1;CM-VER=3.1; Time Not Established Notice (6) Honoring MDD; IP provisioning mode = IPv6 Time Not Established Critical (3) SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing;;CM-MAC=[REDACTED];CMTS-MAC=00:00:00:00:00:00;CM-QOS=1.1;CM-VER=3.1; Tue Dec 03 19:30:11 2019 Notice (6) CM-STATUS message sent.
