frequent network dropoffs

Got it. Thanks. SMART data look good for all disks -- all values 0 except for Start Stop Count, Power On Hours, Power Cycle Count, Airflow Temp & Temp.

Network shows some TCP Retransmits and Unrecovered TCP Retransmits. I have since moved the NAS from one router to the other, disabled journaling, and turned off all the streaming services, which I wasn't using. So far, it seems to be more stable and is even happily doing a TimeMachine backup as I type this.

Skimming through the logs, I wondered if any of these entries are cause for concern:
