Random disconnects have come back

I was facing random disconnects which gradually got worse, comcast eventually ran a new cable for me claiming my current one was too old and could not handle modern internet speeds, things were fine for a bit but now I am dealing with those disconnects again. I cannot access the modem until I reset it. It would be great if someone at comcast can take a look at this and help me troubleshoot the issue because obviously running a new line has not solved it.

Re: Random disconnects have come back

The signal stats are o/k but the error log entries indicate that something is going on. Perhaps there is noise ingress into the line(s) somewhere.

 

There are other signal stat figures that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.

 

I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. They will be able to poll the CMTS to see whether or not everything is in the green zone, see your node / cable plant and modem health, and also see a history plot for the modem. You should get a reply here in your topic. Good luck !

Re: Random disconnects have come back

Hi ishtar96. We appreciate you visiting and posting on our Forums. I can assist with further troubleshooting your intermittent connectivity issues. I will start with polling your CMTS for real-time and also historical RF signal reports produced by your modem. I can also check your local Node/Plant for degradation or error reports. So I can get started, please send me a private message and include your full name so I can access your equipment.

Re: Random disconnects have come back

Thanks Joe, it just randomly went down again and I had to restart the modem.
