Conference calls are pausing for several seconds multiple times a day

I have been have issues with my conference calls pausing during the day.  Some days are worse than others and I have to wait for them to reconnect.  I hve been trying to get to the root cuase and tracking when they happen to look at varous logs on my router.  Last night I decided to look at my modem and foudn that there is a correlation with the timing and this error on my modem - Started Unicast Maintenance Ranging - No Response received - T3 time-out.  Not sure if this is the cause so loking for input and possible resolution.

 

The issue occures if I am wireless or direct to the modem.  Modem is 2 mnths old and a Netgear CM1100.  There is one splitter in the house and nly one cable going to the modem.  No TV or phone service.

 

Thanks

Start with the modem's signal stats. Perhaps they already are, or they are close to being out of spec and intermittently they go completely of spec. 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 ?

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 !
