-First step, make sure you aren't using the orinoco driver. If the interface name is wlan0, then the driver is HostAP or wlan-ng. However if the interface name is eth0 or eth1, then the driver is orinoco and you must disable the driver (use cardctl ident to know you card identifier, then edit /​etc/​pcmcia/​config,​ replace orinoco_cs with hostap_cs and restart cardmgr). ​+First step, make sure you aren't using the orinoco driver.

 Also, it can be a firmware problem. Old firmwares have trouble with test mode 0x0A (used by the HostAP / wlan-ng injection patches), so make sure yours is up to date (see [[prism2_flashing|Prism2 flashing]] for instructions). The recommended station firmware version is 1.7.4. If it doesn'​t work well (kismet or airodump-ng stalls after capturing a couple of packets), try STA 1.5.6 instead (either s1010506.hex for old Prism2 cards, or sf010506.hex for newer ones). ​ Also, it can be a firmware problem.
