Like others I am experiencing internet drops, at times it is every few minutes. I am using a personally owned Arris SB6183 modem. I have a screenshot of the modem Status page if someone can instruct me on how to post it. The outages are happening to wired devices so I am sure it is the modem or the infrastructure. I've called Comcast and went thru the modem reset dance and am in the same place as i started. To troubleshoot I've done the following:
Check wiring including installing new connectors
Ensure only one splitter between modem and incoming service.
Reset modem with online app and customer service representative (CR868270145)
Since you are a new poster, it needs to be approved by a Forum Admin. That could take some time. In the interim you could try hosting it at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to it here.
Just host it at one of those free sites that I mentioned.
The signal stats were o/k at that snapshot in time. Please also post the modem's RF error / event log entries.
Is there a router in the equation here ? if so, for a test, does a computer hardwired directly to 6183 modem have the same problem ?
Computer is hardwired to modem. Lights on modem do not change when internet drops. I'll post the modem logs when i get home this afternoon.
Thanks for your help here EG.
EG - I appreciate you taking the time to answer questions and trying to help. I screenshotted the first page of the modem logs below, there are more pages but they are essentially repeats of what you see in this image. Let me know if i can supply more info that might be helpful in troubleshooting.
Even though the signal stats looked o/k at that snapshot in time, the error log entries confirm 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 can check the CMTS (Cable Modem Termination System) for any real time degradation and / or error reports, see your node / cable plant and modem health, and see whether or not everything is in the green zone. They can also see a history plot for the modem and poll for those upstream receive signal stats.
You should get a reply here in your topic. Good luck !
