As long as your desktop is connecting to the Internet ok, then we can
probably assume everything on that side is setup correctly.
I think the next thing I would try to do is traceroute from your laptop,
to some IP address on the internet. That way, we can see just where your
TCP packets are getting hung up.
To traceroute:
$ /usr/sbin/traceroute 208.20.203.226
The IP address is the static IP of my DSL router. Feel free to try mine,
or another address closer to you.
