Jared,
Here is a transcript of what I did. I booted the machine (it had been off all
night). What is really strange, is that it looked as if the wireless card was
configured properly when I booted up (note it actually got the right mac
address for the ap) but I still could not ping a machine on my network.
My comments are preceded by a '>':
