CM7000 dropping connection. ISP say's time to replace modem
I have a four year old CM7000 modem, firmware version is v1.02.04. About a month ago, my ISP had a major outage in my area. I saw trucks outside of my neighborhood working on something and I was dow...
IF the modem was working before the outages and the ISP made changes, they need to be contacted and they need to look at the cable connections status page and events log and resolve any Errors and Criticals seen here.
Please post a copy and paste of the modems connection status and event log page.

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
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.

Its up to ISP to update any C series modem FW. There is no user updatable FW for C series modems.
Thank you for the reply.
I do not have any splitters, or anything else on this cable. The cable plugs directly into my modem. The cable is good quality cable. I've done the power cycle, multiple times.
Please find attached singles and logs.
Thank you for your assistance.

Some of the channels are at the high power limit and a bit over.
You have correct and un-correctables that should be all zeros.
Check the outside or from wall cabling to ISP service box for any splitters.
You have lots of criticals that shouldn't be tehre. The ISP needs to help with this.
I've scheduled an appointment to have them come out and check the signals.
Would a factory reset help with this? The person on the phone tried to push out an update, but for some reason it failed.
Thanks
