iwl3945 driver needs new firmware
Last modified: 2007-11-30 17:12:13 EST
Running from updates testing.
Both needs iwlwifi-3945-1.ucode
for the iwl3945 driver to work.
That doesn't seem to be available.
There is a patch in those kernels specifically to address this issue. My
iwl3945-equipped box is running 18.104.22.168-57.fc7 and only
Perhaps you are running a different kernel?
That's my kernel, but when I tried to run it /var/log/messages said:

I noticed that the firmware in iwlwifi-3945-1.ucode from the Intel site is not
only in the -1 file, but is a newer version (126.96.36.199) than
iwlwifi-firmware-2.14.4-1 (which is the latest I get from yum).
That message indicates that you don't have any firmware at all. It will
accept either the old or new names, but only uses the new name in the failure
'yum install iwlwifi-firmware' should suffice. I have verified this on both
the -52 and -57 kernels.
Do you have /lib/firmware/iwlwifi-3945.ucode?
That's truely strange. I was running it with the previous kernels. Whatever was
just before 52 in upgrades-testing. I rebooted to 57 and it stopped working with
that error. At that point I also had 52 installed, so I rebooted into that and
had the same problem. I found the message in the log and connected a wired
ethernet, went to the Intel site, grabbed the new firmware, dropped it in place,
and it worked fine.
I do have iwlwifi-firmware-2.14.4-1 installed. Maybe something got corrupted
somewhere. I'll try removing that package and reinstalling it and see what happens.
Just a thought -- did you boot the -52 or -57 kernel _after_ updating the
iwlwifi-firmware package? If you updated iwlwifi-firmware after the failure
and didn't reboot or reload the module then it still would not have worked.
