or if kudzu for some reason doesn't cooperate (which is always on my
system)<br>
become root<br>
run : /sbin/modprobe prism54<br>
run : dmesg | tail<br>
and read whether it just says it has loaded the module (single line) or
<br>
detected will output a wlanX statement and you are in business<br>

creates when of all detected hardware at startup and it related this

but certain drivers are modules in the kernel, wich need to be loaded
manually
or later when the system is already running<br>
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<br>
you will need to add the line (if it is not yet there) :<br>
alias wlan0 prism54<br>
you can check whether the module is loaded with : /sbin/lsmod | grep
