dmesg | grep iwlagn:

The error message from ifup leads me to believe the problem is with a missing
D-Bus service.  When I go to System > Admin > Services (in Gnome), D-Bus is not
listed and an rpm -q for it comes up blank.  Is this something KDE should have
installed during the Fedora installation?  If so, how do I get it?

JD, adding the "-dd" didn't help since the network never gets that far in KDE.

Tim, unfortunately I am unable to get to my router which is located in the
basement and I'm handicapped and can't get down the stairs.  It was setup many
years ago with admin access restricted to wired connection which I don't have
up here.  Hmmm, maybe I need a 100ft patch cord!
