Notes:

• You should always use latests revisions with aircrack-ng (but nothing older than r1486)
• At “make install”, you can be asked if you want to remove old modules, type ‘r’ to do it.
• When using airmon-ng, specify wifiX as interface or you can create manually a VAP in monitor mode with wlanconfig.
• You should delete all existing VAP before before creating a VAP in monitor mode.
• madwifi-ng-r1886.patch still works with latest madwifi version

Known bug: If you change the rate while capturing packets, airodump-ng will stall. There’s 2 possible workarounds:

• Set injecting before starting airodump-ng
• Restart airodump-ng
