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 ?
Thank you for replying,

I'm on a Netgear C7000v2
I don't know if this is what you're asking for: I'm not well versed in internet stuff. 😕
Stat are o/k. Please also post the RF error / event log entries.
Is there any way to get them to *not just* ok??
Here is the error log:
O/k means that they indeed fall in to the ranges for being within the specified operating parameters.
That said, 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 !
My pleasure ! Thanks !
Hi there, Jkirk10. Thanks for posting and for working a little bit with EG. You posting your modem's info like that really helps. I would like to take a look at some other diagnostics on this end as well. Please send me a private message with your first and last name so we can continue from there.
