I consistently get the following errors. Typically they coincide with a brief connectivity outage. 2022-6-29, 06:39:07 Notice (6) TLV-11 - unrecognized OID;CM-MAC=10:0c:6b:6a:8b:18;CMTS-M...
I had one of the disconnects this afternoon and sent these logs to my ISP

Their response:
I apologize for the issues that you are experiencing. As we have already completed a monitor on your modem, and the multiple times of contact between you and us, we have not seen any issues with your modem whatsoever. Unfortunately, we do not go by those logs. The statistics of this modem have not changed over the course of a few days so we do not see any problems with the service. I know as you have previously asked about upgrading firmware, this is not something Service Electric Cablevision will do as you have a third-party Netgear modem. For all of this, this is something you would need to contact Netgear directly for.
I did have a cable splitter, which is now removed from the equation. I'll post if that helps.
Well your on the lower fringes of the power being a bit too low. Would be good if the power could come up just a bit.
Hoping the removal of the splitter can help.
All those events posted can only be controlled by the ISP. The mode is just reporting what is happening.
You have a few correct and un-correctables. Ensure all connections and fittings are snugg.
Good quality RG6 coax cable is recommended.
Removing the splitter had a definite impact on the power. I'm really hoping this resolves this issue. Time will tell!
