HostAP is the recommended driver for Prism2.x/3 based pcmcia and pci cards. Official web site is at

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).

If you're using a kernel version >= 2.6.16, you have to patch kernel sources with this patch hostap-kernel-2.6.16.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
tar -xvzf hostap-driver-0.4.9.tar.gz
cd hostap-driver-0.4.9
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
