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-MAC=00:01:5c:7b:3a:4c;CM-QOS=1.1;CM-VER=3.0;
2022-6-29, 06:39:11	Error (4)	Improper Configuration File CVC Format

I followed guidance based on these 2 articles:

I got to the point where it seems prudent to do a firmware update.

Per this article https://kb.netgear.com/000036375/What-s-the-latest-firmware-version-of-my-NETGEAR-cable-modem-or-modem-router

I found that my firmware is out of date and the ISP needs to do it.

Response from my ISP:

My apologies for the inconvenience. Service Electric does not roll out firmware updates on Netgear modems. It is possible Netgear may be able to assist you in updating the firmware.

How am I supposed to get my firmware updated assuming that will actually resolve the errors?
