HostAP

HostAP is the recommended driver for Prism2.x/3 based PCMCIA and PCI cards. The driver official web site is at http://hostap.epitest.fi.

Patching

If you're using a kernel version >= 2.6.16, you have to patch kernel sources with hostap-kernel-2.6.18.patch patch instead of using the following method:

ifconfig wlan0 down
wlanctl-ng wlan0 lnxreq_ifstate ifstate=disable
/etc/init.d/CardBus stop
rmmod prism2_pci
rmmod hostap_pci
wget http://hostap.epitest.fi/releases/hostap-driver-0.4.9.tar.gz
tar -xvzf hostap-driver-0.4.9.tar.gz
cd hostap-driver-0.4.9
wget http://patches.aircrack-ng.org/hostap-driver-0.4.7.patch
patch -Np1 -i hostap-driver-0.4.7.patch
make && make install
mv -f /etc/pcmcia/wlan-ng.conf /etc/pcmcia/wlan-ng.conf~
/etc/init.d/pcmcia start
modprobe hostap_pci &>/dev/null

Troubleshooting

If your card appears to hang (no packets captured or injected), disable the interface, reload the drivers and re-insert the card. Also consider updating the firmware (if prism2).

Limitations

There are some important limitations with this driver:

  • Fragmentation attack does not work
  • Shared key authentication attack does not work
  • The driver does not support USB devices
