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