I think arp shows your adapter's neighbors, not the adapter itself. I only just read the man page for the first time, however, its results when I run it seem to confirm that: 192.168.1.1 ether 00:18:4D:25:82:0D C ath0 My adapter's neighbor is, indeed, 192.168.1.1 (my router). ifconfig, on the other hand, seems like a much better place to find info about the device, itself. Also, the address it gives for my device matches the sticker that the manufacturer put on my laptop. :) -Bryan
