Hi, I followed the instructions here: http://osxdaily.com/2007/01/18/airport-the-little-known-command-line-wireless-utility/ to use the airport from the command line. The problem is, I cannot get any of the functions to work except association via SSID. I cannot set a channel on the card and I cannot associate via BSSID. I have tried every iteration of those commands I could come up with to no avail. Could someone please give me an example of a command that works on their computer? I am running 10.5.1 on a C2D MB. Thanks in advance.
