Night Hawk CM1200 Downstream Blinking
Off and on my downstream led starts blinking and I loose my internet. I have seen some previous posts but I though I would post my connection. Looks like 24 is an issue. Any guidance is appreciate...
Have the ISP take a look at the information I pointed too.
Power is too LOW and you have a ton of correctables and un-correctables that should be zeros.

Please post a copy and paste of the modems event log page.

Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

This has been going on for weeks but today it is horrible. However, Comcast just informed me that they are working on a outage in my area. So when it gets resolved I will clear the logs and get some fresh info. thanks for the help
Ok. Most of the time it's an ISP issue.
Let us know how it goes after they complete there work.
After the outage yesterday, today I started losing my downstream at times again. My work computer uses a VPN. When I finally got hold of a Comcast agent and going through all the reboots they blamed it on my VPN. So I said I will disable the VPN this weekend and if it fails then send an tech out. Here are my current logs. what do you think.
