or if kudzu for some reason doesn't cooperate (which is always on my

become root

run : /sbin/modprobe prism54

run : dmesg | tail

and read whether it just says it has loaded the module (single line) or

detected will output a wlanX statement and you are in business


  Isn’t it
implied that since ”prism54” is listed in /etc/sysconfig/hwconf for the
wifi-card that the module has been loaded already? Or is this some of

/etc/sysconfig/hwconf is the file kudzu creates when of all detected
hardware at startup and it related this hardware with drivers in the

but certain drivers are modules in the kernel, wich need to be loaded
manually or later when the system is already running

this can be done by method 1 explained here above or adding them in
/etc/modprobe.conf which makes it load the modules at startup

you will need to add the line (if it is not yet there) :

alias wlan0 prism54

you can check whether the module is loaded with : /sbin/lsmod | grep
