I assume you're using Fedora 7 since you don't mention
installing the driver.  This means you're using the iwl3945
driver.  You might like to try the older ipw3945 driver, to do

To /etc/modprobe.d/blacklist add:
blacklist iwl3945
blacklist mac80211

>From Freshrpms use yum to install:
ipw3945d ipw3945-firmware dkms-ipw3945

And restart.  The device will be ethX rather than wlanY.
If that works you may want to file a bug for iwl3945
(I believe it should be filed against the kernel).
What model is the card you're using?  Is this a laptop?
