It appears that 2.2.20 brought back the db maintenance\network drop issue from several versions ago. Each day, my Tablo starts flashing slow and drops its IP address since I updated. And, every day I have to unplug the Tablo, delete the static IP set in my router, reboot router, wait ten minutes and plug Tablo back in, and then setup static IP address again. While this is a tedious procedure, it has worked for several days until today! Now, no matter how long I leave Tablo unpluged, it still comes back up flashing. Before I submit a ticket with @TabloSupport, I wanted to see if anyone else is experiencing a similar issue.
