This is how I got my Buffalo WLI-CB-G54 wireless network card to work on Ubuntu Linux, the same procedure applies for any linux distribution.

• Get latest driver for the WLI-CB-G54 from here:

   http://buffalo.bmcdn.jp/buffalo/lan/wdrv_660.exe
   or here http://www.codealias.info/pkgs/wdrv_660.exe

• extract it :

   wine wdrv_660.exe

• Install “bcm43xx-fwcutter”:

   apt-get install bcm43xx-fwcutter

• Extract the chipset firmware

   sudo bcm43xx-fwcutter -w/lib/firmware/ /tmp/wdrv_660/CBG54/bcmwl5.sys

• Plug the card (it appreas as “ethx” )

• Test it

   $iwpriv eth1

   eth1 Available private ioctls :
   set_interfmode (8BE0) : set 1 int & get 0
   get_interfmode (8BE1) : set 0 & get 80 char
   set_shortpreamb (8BE2) : set 1 int & get 0
   get_shortpreamb (8BE3) : set 0 & get 80 char
   set_swencrypt (8BE4) : set 1 int & get 0
   get_swencrypt (8BE5) : set 0 & get 80 char
   write_sprom (8BE6) : set 512 char & get 0
   read_sprom (8BE7) : set 0 & get 512 char

As you can see, limited capabilities (no wpa)
