-The presence of a [phy0] tag at the end of the driver name is an indicator for mac80211, so the Broadcom card is using a mac80211 driver. **Note that mac80211 is supported only since aircrack-ng v1.0-rc1, and it won't work with v0.9.1, which this tutorial primarily refers to.**+The presence of a [phy0] tag at the end of the driver name is an indicator for mac80211, so the Broadcom card is using a mac80211 driver. **Note that mac80211 is supported only since aircrack-ng v1.0-rc1, and it won't work with v0.9.1.**
 Both entries of the Atheros card show "​madwifi-ng"​ as the driver - follow the madwifi-ng-specific steps to set up the Atheros card. Both entries of the Atheros card show "​madwifi-ng"​ as the driver - follow the madwifi-ng-specific steps to set up the Atheros card.
 Finally, the Ralink shows neither of these indicators, so it is using an ieee80211 driver - see the generic instructions for setting it up. Finally, the Ralink shows neither of these indicators, so it is using an ieee80211 driver - see the generic instructions for setting it up.

 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 card MAC address in the AP field, other drivers do not.  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 card MAC address in the AP field, other drivers do not.  So everything is good.   It is important to confirm all this information prior to proceeding, otherwise the following steps will not work properly.
