I ran into a problem with multiple NICs after a complete install of Fedora
8.  In my case I had a NIC connecting to a wireless router and another
connecting to another router that connects to the cable modem.  Since the
wireless router daisy-chained through the regular router to get to the
Internet I had multiple possible routes to the Internet and it appears to
have confused my computer, even though everything looked fine.  In my case
it healed itself in about a day.

So what I'm asking, is there any way your computer could be confused about
the correct path to the Internet?
