 In the response above, you can see that ath0 is in monitor mode, on the 2.452GHz frequency which is channel 9 and the Access Point shows the MAC address of your wireless card.  Only the madwifi-ng drivers show the MAC address of the card in the AP field, other drivers do no.  So everything is good.   It is important to confirm all this information prior to proceeding, otherwise the following steps will not work properly. In the response above, you can see that ath0 is in monitor mode, on the 2.452GHz frequency which is channel 9 and the Access Point shows the MAC address of your wireless card.  Only the madwifi-ng drivers show the MAC address of the card in the AP field, other drivers do no.  So everything is good.   It is important to confirm all this information prior to proceeding, otherwise the following steps will not work properly.
