What is the meaning of a ti_dhcp6c "critical" Event Log entry in a DG3450A?

Question

I’m concerned about occasional short-term disconnections from the Internet (WiFi is off). The System Log is clean but the Event Log shows hundreds of entries like:

ti_dhcp6c: 72001004-DHCPv6 Provision - 121 Retries Attempted with Last attempt at Fri Sep 22 23:19:42 2023
09/22/2023 23:21:49 Critical

Thank you for sharing the cable signal levels, we want to update you that the modem (DG3450A) is not supported by Arris .

Arris supports only the retail products that are available on surfboard.com but not the ISP lease products.

Please contact your ISP for further assistance.

Helloagropper             The logs are Values read by technicians from the internet provider end, since the logs are what the coaxial cable transmits and the log screen on the router is the translator so can be easily read by them, the coaxial cable is owned by the Internet service provider.If your Event Log is reporting a high volume of errors, this would indicate a potential CMTS signal issue. To troubleshoot these errors, we would like to note the current signal levels being used by your (DG3450A).
