CM400 modem keeps disconnecting from ISP
Had the CM400 for about 6 months now, replaced the delivered comcast one which it outperformed. Now the past week it randomly disconnects, the downstream and upstream lights start blinking green, the modem seems to reboot(i think its doing this as i cannot login to it) and then the upstream and downstream lights turn Orange. Then sometime later it will do it over again and then the upstream/downstream lights will now be green. When the lights are orange, i only have one upstream and one downstream channel locked, when it goes back to green i have 8 down and 4 up. When i only have a single stream, everything is pretty laggy, gaming is a problem though streaming is not. It can switch between orange and green 2 or 3 times within an hour or go a day without doing it, when it does this i have several minutes of no internet access. Is this a comcast problem ? or is this a faulty modem ? I did call comcast but they just said faulty modem, but i have my doubts. This is the channels i have now, both up and downstream lights are orange: <tabindex=-1>Downstream Bonded Channels Channel Lock Status Modulation Channel ID Frequency Power SNR Correctables UnCorrectables 1 Locked QAM 256 9 687000000 Hz 2.3 dBmV 37.9 dB 35 1958 2 Not Locked N/A N/A 0 Hz 0.0 dBmV 0.0 dB 0 0 3 Not Locked N/A N/A 0 Hz 0.0 dBmV 0.0 dB 0 0 4 Not Locked N/A N/A 0 Hz 0.0 dBmV 0.0 dB 0 0 5 Not Locked N/A N/A 0 Hz 0.0 dBmV 0.0 dB 0 0 6 Not Locked N/A N/A 0 Hz 0.0 dBmV 0.0 dB 0 0 7 Not Locked N/A N/A 0 Hz 0.0 dBmV 0.0 dB 0 0 8 Not Locked N/A N/A 0 Hz 0.0 dBmV 0.0 dB 0 0 <tabindex=-1>Upstream Bonded Channels Channel Lock Status US Channel Type Channel ID Symbol Rate Frequency Power 1 Locked ATDMA 2 5120 Ksym/sec 29500000 Hz 47.3 dBmV 2 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 47.3 dBmV 3 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 47.3 dBmV 4 Not Locked N/A Unknown 0 Ksym/sec 0 Hz 47.3 dBmV Any help much appreciated.
