Got it working ... well at least I have the wifi LED blinking
But I am not too sure how to load it automatically.
The instructions says :
you typically place the following two lines into
your /etc/modprobe.conf or into a new file /etc/modules.d/ipw3945:
# echo install ipw3945 /sbin/modprobe --ignore-install ipw3945 ; \
sleep 0.5 ; /sbin/ipw3945d --quiet >> /etc/modules.d/ipw3945
# echo remove ipw3945 /sbin/ipw3945d --kill ; \
/sbin/modprobe -r --ignore-remove ipw3945 >> /etc/modules.d/ipw3945
But the directories and files does not seem to exist in my updated installation. Appreciate your guidance. Thanks!
