Missing Required Option 82

My router repeatedly shows error log entries such as these:

DHCPv6[8824]: 72001011-DHCPv6 - Missing Required Option 82 2025/7/28 03:31:25 Critical
DHCPv6[8824]: 72001011-DHCPv6 - Missing Required Option 24 2025/7/28 03:31:25 Critical

The Troubleshooting bot hasn't been able to identify anything wrong with the signal to my home or my router. The event logs show that this round of error entries started on July 1. (There'd been a similar occurrence in late April.) I have the log file but I won't dump the 2200 line file here.

The concern is not "Community Knowledge Base" related............ Topic moved here to the proper help section for assistance.

@user_cx2cniCan you tell us more about what's going on? Are you also having issues with your phone or internet services such as slow or no connection?

Is this your own purchase router that's giving you those errors?

Are you seeing this error across multiple devices or just one?

The event logs are on the Xfinity router. I haven't noticed any issues with the quality of my connections.

If there are no connectivity issues, I wouldn't sweat the log entries.

Xfinity tech support remotely inspected the browser, and, I assume, tweaked a few things not accessible by mere mortals. There have been no error entries in the log file in the four days since the reboot.
