It's only every 4-6 months, so, infrequent enough that I've usually just 
given up, and then it's magically repaired.  I didn't consider rebooting 
the modem under these circumstances, since the modem indicates a 
connection with a solid light for "internet," but that's probably the 

As best I recall ifconfig was just blank on IPv4 address, but did 
indicate an IPv6 address.  (A minor advantage of IPv4, to my mind, is 
that it's easily human readable.  I'm sure some can translate the hex to 
decimal in their head, but not me.)  I found it odd that that the IPv4 
field was empty.

Next time I'll reboot the modem (unplug, leave unplug 3+ minutes is 
pretty standard) and try that :)
