Prism II/2.5 cards can support wireless authentication with WPA/WPA2 in using the hostap driver that comes with the wpa_supplicant package.

In order to do so, the firmware version of your card must be newer than the version 1.7.x. In this howto, you will learn how to check and upgrade Prism II/2.5 firmware to support the hostap driver.

Steps

Install hostap tools

  $sudo apt-get install hostap-utils

Check the version of your firmware

  $hostap_diag wlan0

Get the station firmware (sf010804.hex) and the primary firmware (su010804.hex) from here: http://www.codealias.info/pkgs/prism-firmware-1.8.4/

Check for compatibility
