Good thought.  I have mine set up for a static IP address though.  

Where have you set up static IP?  Does your router know it’s supposed to be using a static IP, or does it think it should be assigning an IP using DHCP…?

A firmware upgrade may well trigger re-running of the indexing and thumbnailing tasks:
