To make sure you have the correct firmware
yum install iwlwifi-3945-ucode.noarch
rpm -qa | grep iwl | sort
Also, you should completely get rid of the ipw3945 stuff, or it will
keep creeping in and messing things up.
/etc/rc.d/init.d/ipw3945d stop
yum remove "*ipw3945*"
It would be a good idea to reboot after this.
