You can find more information at Wifitap webpage, especialy for drivers support. As Wifitap relies on traffic injection, it will only work with drivers capable of raw 802.11 traffic injection. For now, as far as I know, supported drivers are:

  • Intersil PrismGT FullMAC with prism54 driver
  • Atheros with Madwifi driver (old and ng supported)
  • Intersil Prism2/2.5/3 with hostap or wlan-ng driver
  • Ralink rt2500/2750 with rt2500 driver
  • Realtek RTL8180 with rtl8180-sa2400 driver

Required patches can be found on Aircrack-ng website. Bcm43xxx early support is also available and Intel IPW2200 may be working as well, although I did not test them[1].

The excellent WirelessDefence.org also wrote a comprehensive introduction to Wifitap you may want to read if you still find my README a bit too cryptic. Also note that Wifitap is now bundled with BackTrack, a complete and powerful penetration testing oriented live distribution.

Last, but not least, I'd like to thank Philippe Biondi for his help and advises, and of course for Scapy.
