Hey all, I have a brand new Netgear CM1200 modem and Netgear R7000 router. My ISP is Spectrum. On my first day, my upstream light was blinking, but after restarting my modem, now I have a consistent amber light. The downstream light was solid green on my first and second day, but on my third day (Saturday), I've seen it blink once. I fixed this by turning on my fan since I felt my modem was getting a bit hot. Here's my Event Log:Sat May 09 14:14:30 2020Notice (6)CM-STATUS message sent.

Have the ISP check the signal and line quality UP to the modem. Be sure there are not coax cable line splitters in the between the modem and ISP service box. Be sure your using good quality RG6 coax cable up to the modem.

After turning off my modem for a few ho and powering it back on after a lengthy period, my upstream light is now flashing green.Startup ProcedureProcedureStatusCommentAcquire Downstream Channel765000000 HzLockedConnectivity StateOKOperationalBoot StateOKOperationalSecurityEnabledBPI+IP Provisioning ModeHonor MDDhonorMdd(4) Downstream Bonded Channels (Partial Service)ChannelLock StatusModulationChannel IDFrequencyPowerSNRCorrectablesUncorrectables1LockedQAM25631765000000 Hz9.4 dBmV41.5 dB002LockedQAM2561585000000 Hz8 dBmV42 dB003LockedQAM2562591000000 Hz8 dBmV42.1 dB004LockedQAM2563597000000 Hz8.1 dBmV37.6 dB005LockedQAM2564603000000 Hz8.1 dBmV40.8 dB006LockedQAM2565609000000 Hz8.1 dBmV42.2 dB007LockedQAM2566615000000 Hz8 dBmV42.1 dB008LockedQAM2567621000000 Hz8.1 dBmV42.1 dB009LockedQAM2568627000000 Hz8 dBmV42 dB0010LockedQAM2569633000000 Hz7.5 dBmV41.7 dB0011LockedQAM25610639000000 Hz5.8 dBmV41 dB0012LockedQAM25611645000000 Hz5.9 dBmV41.1 dB0013LockedQAM25612651000000 Hz6.9 dBmV41.4 dB0014LockedQAM25613657000000 Hz7.8 dBmV41.6 dB0015LockedQAM25614663000000 Hz8.5 dBmV41.7 dB0016LockedQAM25615669000000 Hz8.9 dBmV41.8 dB0017LockedQAM25616675000000 Hz9.5 dBmV41.5 dB0018LockedQAM25617681000000 Hz9.2 dBmV41.9 dB0019LockedQAM25618687000000 Hz8.3 dBmV41.6 dB0020LockedQAM25619693000000 Hz8.7 dBmV41.6 dB0021LockedQAM25620699000000 Hz8.9 dBmV41.8 dB0022LockedQAM25621705000000 Hz8.9 dBmV41.7 dB0023LockedQAM25622711000000 Hz8.3 dBmV41.5 dB0024LockedQAM25623717000000 Hz7.6 dBmV41.3 dB0025LockedQAM25624723000000 Hz7.5 dBmV41.2 dB0026LockedQAM25625729000000 Hz8.4 dBmV41.3 dB0027LockedQAM25626735000000 Hz9.1 dBmV40.7 dB0028LockedQAM25627741000000 Hz9.6 dBmV40.1 dB0029LockedQAM25628747000000 Hz10 dBmV39.8 dB0030LockedQAM25629753000000 Hz10.3 dBmV39.1 dB0031LockedQAM25630759000000 Hz10.1 dBmV41.7 dB0032Not LockedUnknown00 Hz0.0 dBmV0.0 dB00 Upstream Bonded Channels (Partial Service)ChannelLock StatusUS Channel TypeChannel IDSymbol RateFrequencyPower1LockedATDMA15120 Ksym/sec17400000 Hz49.5 dBmV2Not LockedUnknown20 Ksym/sec17400000 Hz0.0 dBmV3Not LockedUnknown30 Ksym/sec23800000 Hz0.0 dBmV4Not LockedUnknown40 Ksym/sec36600000 Hz0.0 dBmV5Not LockedUnknown00 Ksym/sec0 Hz0.0 dBmV6Not LockedUnknown00 Ksym/sec0 Hz0.0 dBmV7Not LockedUnknown00 Ksym/sec0 Hz0.0 dBmV8Not LockedUnknown00 Ksym/sec0 Hz0.0 dBmV Downstream OFDM ChannelsChannelLockStatusModulation /Profile IDChannelIDFrequencyPowerSNR /MERActive SubcarrierNumber RangeUnerroredCodewordsCorrectableCodewordsUncorrectableCodewords1Locked0 ,1159300000000 Hz6.0 dBmV42.1 dB1108 ~ 29873233898184353902Not Locked000 Hz0 dBmV0.0 dB0 ~ 4095000 Upstream OFDMA ChannelsChannelLock StatusModulation / Profile IDChannel IDFrequencyPower1Not Locked000 Hz0 dBmV2Not Locked000 Hz0 dBmV As you can see, I do have a locked bonded channel.

Sorry to respond late; I wanted to test my connection for an extended period of time. That said, I do want to follow up in case anyone else from the future is searching for an answer to their problem and stumbles across this thread. Shortly after your response, I made a call to Spectrum. They tried out some solutions before scheduling a tech to come diagnose my issue. Here's where it gets interesting—the appointment was canceled on the day of, with no explanation; I also never followed up because my internet was just magically working. My modem has maintained an amber light since that day, but my connection never drops. The modem doesn't get worryingly hot either.

Might check the channels on the modem to see what is locked in. The ISP may have made some changes on there side. You miight power OFF the modem for 1 minute then back on to see if the LEDs changes.

Do you have an update since your last response? Is the upload light blinking and loss of connection resolved? Sounds like it was a fix on spectrum side. I had purchased a CM1200 back in March and had this same issue. Thinking that it was a defect with the modem I exchanged it for another new one but the new one also had the same problem after a couple days. When it worked, the CM1200 was getting great speeds. I ended up returning it for a refund. But if this problem is fixed, I'm thinking of buying it again. Can you confirm on your side please?

CM1200 Amber Upstream Light and Occasionally Blinking Downstream Light

Hey all,

I have a brand new Netgear CM1200 modem and Netgear R7000 router. My ISP is Spectrum.

On my first day, my upstream light was blinking, but after restarting my modem, now I have a consistent amber light. The downstream light was solid green on my first and second day, but on my third day (Saturday), I've seen it blink once. I fixed this by turning on my fan since I felt my modem was getting a bit hot.

Here's my Event Log:

Would appreciate any thoughts I can get on this matter. Mostly looking to get rid of my amber light if possible, and figuring out why this modem gets a bit hotter than my old modem.

After turning off my modem for a few ho and powering it back on after a lengthy period, my upstream light is now flashing green.

As you can see, I do have a locked bonded channel. My upstream power is less than last time, which I would prefer. But my internet drops if I upload something.

Have the ISP check the signal and line quality UP to the modem.
Be sure there are not coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.

  Sorry to respond late; I wanted to test my connection for an extended period of time. That said, I do want to follow up in case anyone else from the future is searching for an answer to their problem and stumbles across this thread.
  
  Shortly after your response, I made a call to Spectrum. They tried out some solutions before scheduling a tech to come diagnose my issue. Here's where it gets interesting—the appointment was canceled on the day of, with no explanation; I also never followed up because my internet was just magically working. My modem has maintained an amber light since that day, but my connection never drops. The modem doesn't get worryingly hot either.

    Might check the channels on the modem to see what is locked in. The ISP may have made some changes on there side.
    
    You miight power OFF the modem for 1 minute then back on to see if the LEDs changes.
