We try, we try.  Don't get too used to it.  It's sort of a slow day
here today.

iwconfig should be in /sbin and is part of wireless-tools.

When you did it as root, did you log in as root or do an "sudo" or "su"?
If you did an "su", you have to do "su -", as /sbin is only in root's
path after a login (or a simulated login as "su -" does).  Check the
path as root ("echo $PATH") and verify that /sbin is in it.  Or, you can
fake it via:

	/sbin/iwconfig -a
