Looks to be correct.  I double checked in Fedora 10 and Fedora 11 and it is about the same.  I did not check selinux contexts though :(

You are connecting via dialup or wireless broadband?  

How long does the connection last?  If you do a restart ?
something like 
# service NetworkMangager stop
# service NetworkManager start

take a look at output of 
# ifconfig -a
and/or system logs to find what is causing this.  also dmesg can see if a driver or kernel module caused the stoppage?

Antonio
