I can assure you this isn't a Fedora Core 4 problem necessarily.  It's
definitely a network issue somewhere in the software probably, since it
is affecting all apps.

I'd definitely disable SELinux entirely.  Then make sure iptables is off
and won't be running at boot:

/etc/init.d/iptables stop
/sbin/chkconfig --level 35 iptables off

What does traceroute reveal?  If you /usr/sbin/traceroute
does it get all the way?

What are your routes (/sbin/route -n)?  Recently I heard from someone
that had a problem with the wireless and wired interfaces being routed
at the same priority, causing all kinds of odd packet loss issues.

I doubt that'd be effective.  However trying out another distro (say
Ubuntu) as a sanity check might be good.  That way you can rule out some
kind of hardware/network problem.
