CM700 Channels 19-22 correctable/uncorrectable error build up killing ISP
I have an approximately five year old CM700 Cable modem. Up until the past few days I have had no issues with it.
W/in the past few days the internet in my house has been dropping intermittently (3-4 times a day). No reported outages in my area from my ISP. Rebooting the modem/wi-fi router always corrected the issue.
After it happened again today, I called the ISP and they said they could see errors building rapidly within the modem. I confirmed with the attached.
I have confirmed my coax connections @ the modem and the wall are tight. Are there any other things I should look for?

Update: errors now building on channels 23-25 as well.
Please post a copy and paste of the modems entire connection status and event log page.

https://kb.netgear.com/30008/How-do-I-view-or-clear-the-event-logs-on-my-NETGEAR-cable-modem-or-modem-routerIF there are lots of correctables and un-correctables, which should be mostly zeros, 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.
