Sorry for the previous message ....,
Thanks for the response but, if i install a freebsd and edit an image of monowall,
can i add the driver ( i don't know how ) i want and just re-form the image of m0n0wall
like in this documentation http://jief.theroux.ca/docs/custom-m0n0wall-howto.txt
or it is not sure to be a solution and must be more complexe to do.
My complete installation is WRAP 1.E with min-pci card intel PRO/Wireless 2200BG
( driver ipw 2200).
