What do the modem's signal stats look like ? Try getting them here http://192.168.100.1 or here http://10.0.0.1
Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
What is the exact make and model number of the modem ?
Are you using http://192.168.100.1 as the access IP address ?
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.
Yes. And once the internet connection was regained I was able to reach that address.
Yes that is typical behavior for most modems. The signal stats looked good at that snapshot in time. Please post the RF error / event log entries as well.
Yes. Sorry, I somehow lost track of your topic here..
Even though the signal stats looked o/k at those snapshots 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 !
Great thanks for the assistance.
I think I forgot to mention that this almost only happens when the outside temp is above 90 degrees. I rarely have an issue during the winter.
Thank you for sharing the detail of the experience you're having with your internet. I'd like to check your premise signal and the health of your node to help determine the cause of your issues.
