Intermittent connectivity issues

For the past few months, we've had intermitten connectivity issues. Each event typically lasts somewhere from 30 seconds to a few minutes and honestly, we haven't done anything about it since it usually resolves quickly. That has changed over the past few days. We now have connectivity drops multiple times a day and it is impacting our ability to work from home. I believe the issue may be an upstream or downstream power issue and I think we need support from a Comcast technician. Here's what we're running:

  • Netgear CM600 modem
  • Netgear Nighthawk R7000P wiFi router

I do not believe the issue is related to the Nighthawk router. The LAN is up and I am able to access network resources (I run a little Synology NAS on my network) while connection to external Internet is unavailable.

 

You can see modem settings and event log here (made screenshots public): https://drive.google.com/drive/folders/1mvpvFrhivTXVv9F6M9_YUCajIsdFEFYB?usp=sharing

 

Concerning splitters and cable line quality - the line coming into the wall outlet is joined to an extended coax line provided by Comcast and is fairly new (so no splitter, to my knowledge), which goes directly to my modem. It's possible that some other part of the coax (coming from outside into my house) needs repair, but I do not have the tools to assess this.

 

Any thoughts or help or escalation to the appropriatey skilled Comcast technician would be greatly greatly GREATLY appreciated.

Im having the same issues with a CM1200. Have you gotten any headway on this? Ive had 2 techs out and they both said the same thing. Everything looks good and its your modem.
