| Critical (3) | Unicast Ranging Received Abort Response - Re-initializing |
| Notice (6) | Honoring MDD; IP provisioning mode = IPv6 |
Also, over the course of 10 minutes earlier today, there are 41 event log entries.

I'm seeing the same problems with my C7000 on Comcast. Firmware is version 1.01.23.

Here are the usual entries I see in my event logs:
- Critical (3): SYNC Timing Synchronization failure - Failed to acquire FEC framing;
- Critical (3): Started Unicast Maintenance Ranging - No Response received - T3 time-out;
- Critical (3): No Ranging Response received - T3 time-out;
- Warning (5): Dynamic Range Window violation
- Critical (3): Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out;
