Comment 61 for bug 185470

I did most of what techatdd suggested and it worked for me.

1) I did a 'modprobe -r iwl3945' and 'modprobe iwl3945'

2) I installed linux-backports-modules-hardy.

3) I ran 'depmod -ae'

4) I rebooted.

5) It worked!

I don't know if any the above steps can be eliminated or not.

Thanks for everyone's input.
