CM700 - Intermittent disconnects, reboot fixes it (errors in log)

Hi Netgear community,

 

Hoping you folks could shed some insight for a problem I've been having lately.

As of the last few weeks I've experienced my internet going down at random intervals. So far I've noticed that rebooting my cable modem (CM700) is the only thing that brings everything back online for a while, so I've isolated it to that. I tried a factory reset on the modem, but I just had another incident this morning (Jan 22, 2022 11:41am ET). Checking the logs, I do see a few errors and would like to figure out what they're about before I resort to buying a new modem. Any help would be great!

 

I've copied the cable connection log and event log to Pastebin since the forums claimed they exceeded the 20,000 character limit.

Thanks in advance,

    You've got a lot of power notices in your logs. 

    You'll want to check your line. 

    Remove any splitters, amplifiers, or signal attenuators from you line. 

    Check the line for damage, kinks, old/bad/cheap connectors and remove them if you do. 

    Preferably move the modem to right where the coax comes into the home. 

    If that doesn't help and you're still getting the dynamic range window violations, then the ISP would need to check the line. 

    It could be the modem but not usually when you have those errors
