Thanks Bill.


 I wondered about resolv.conf and here is what it says.  Note that I 
have NetworkManager running:


   $ cat /etc/resolv.conf
   # generated by NetworkManager, do not edit!

   ; Use a local caching nameserver controlled by NetworkManager

   search myhome.westell.com

   nameserver 127.0.0.1


myhome.westell.com  is the DSL modem/router .   I was expecting to see 

nameserver 192.168.1.1

 instead of 127.0.0.1, since that is how my FC6 machine is running, but 
I've not been able to determine where I should change the configuration 
so this occurs.  Since NetworkManager is running changing resolve.conf 
directly fixes nothing since it changes it on the fly.
