Initial setup of the ipw3945 on Fc6, wasn't straight forward,

need to switch my i386 kernel to an i686 so it could match the

used freshrpms.... it would eventually started working.

After my last update to kernel 2.6.20-1.2962 my eth1 just
disapeard.... no messages on the /var/messages the /sbin/ipw3945d
when forced to started just complains:

And got it back to life.

You will have to do this on every kernel update, unless you get the
proper module for your kernel installed from ether atrpms or
freshrpms. You need to match both the arch (i686) and kernel
version. The same module does not work for the standard kernel, and
the ZEN kernel, for example.

You will also want to install the proper yum plugin so that the
kernel in not updated before the module is available. (fedorakmod is
one, and I forget the name of the other...) I run the same module on
my laptop, and it gets installed with the updated kernel without
extra effort on my part.

If you use dkms-ipw3945 from Freshrpms the module gets
rebuilt whenever you boot into a new kernel, meaning
you don't have to wait for a new package to be built
and the package doesn't need updated unless there's
actually a new release of the module.

Most (all?) of the drivers available from Freshrpms work
this way (i.e. they use dkms).
