high ping, packet loss mostly peak hours (sometimes random)

What do the modem's signal stats look like when it's occurring ? 

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 ?

Is this a WiFi connection ?

Can't see your pics. Since you are a new poster, they need to be approved by a Forum Admin. That could take some time. In the interim, you could try hosting them at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to them here.

Hi there,

Technicolor CGM4140COM , Below posted and also my pingplotter from 6am to noon

Please post all of the downstream channels.

And again, is this a WiFi connection ?

Also i am connected into the ethernet running through my house

Sorry, here's imgur link

O/k the signal stats are good.  Perhaps there is intermittent noise ingress into the line(s) somewhere. Or the problem may be a local capacity / traffic congestion issue.

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 !

Thanks for the help!
