I don't know about ath5k, but in usb8388 firmware (libertas driver) there is a blinding table, into which MAC addresses were inserted, so that the firmware would simulate test conditions. Without a blinding table, sometimes nodes with minimal transmit power, distance, and shielding, could still be reached. RF sometimes works better than you want. -- James Cameron http://quozl.linux.org.au/ -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
