Modem keeps dropping

A few days ago I woke up to my phone saying there was no internet on the WiFi network. I have a Netgear CM1200 modem and an Orbi Mesh router.

I rebooted the modem and everthing was fine. A couple of days later the same thing. Not it's every day, and a few times during the day. I've contacted Comcast, they say all the tests are fine and it's the modem, I called Netgear and since I bought it in September and it's over 90 days I need to pay for support.  But netgear assured me it's not hardware.

I just took some screen shots of the modem status and logs. Granted it's all working right now and I'll try when it's not working. but anyone have any ideas?

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.


Or copy all of the text of the status page and paste it into the body of your next post here.

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 !

We have been told that they are currently having issues with the escalations coming into their team correctly. They currently are working to get this resolved, so they will most likely be delayed for multiple days. I can try re-escalating this after a while.

Hi spratke, thank you for creating a post. It sounds like we may need to get a tech out to look into this for you at your home, but first I'd like to run some tests and check your signal health from my end. With the pandemic impacting so many jobs, and forcing us to work from home I know it is imperative that you have a reliable connection. For further assistance in getting this issue resolved, please send me a private message with your full name by clicking on my name (ComcastAmir) and then click "Send a message".

It's still dropping every morning around the same time.  It doesn't happen outside the 4am-6am window though.

11:12 on 1/30 uplink light was blinking and I could connect to the modem to view logs.  I verified that I was on the local WiFi network ping to 192.168.100.1 timed out

I ended up needing to reboot the modem to recover internet after waiting 5 minutes.

Tech just left, he tested our lines and said that the up channels were all over the place, and barely was getting 3 to connect.

Went outside and looked on the pole, said "the plate is super rusty and old, one of the worst I've seen".  

He scheduled maintenance to come out and replace the plate.  I'll post after that happens.
