[DM-MUG] Can't get rid of "self-assigned IP address"

Probably unrelated, but I was having trouble with my AirPort Express  
Thursday night.  The diagnostics said everything was fine to ISP, but  
still couldn't connect to internet.  My Windows machine was  
connecting fine via ethernet, so I knew ihe problem was AirPort  
related.  After launching the AirPort utility, I was informed there  
was a new version of the AirPort software ready to upload to the  
Express.  After doing so, my Macs were able to connect to internet  
normally.  Either the new AirPort software resolved something, or  
else the simple act of a restarting the AirPort (via software  
command, not just pluggling/unplugging, which did NOT help when I  
tried that earlier).
