This guide will help you configure the latest iwlwifi module for the Intel 3945ABG and 4965ABG wireless controllers under CentOS and Red Hat Enterprise Linux 5. For those that don't know, CentOS 5 and Red Hat Enterprise Linux 5 are basically the same thing just with a different name so this guide applies to both.
We will be using 'nano' as our text editor of choice but you can use whatever you wish.
You should run a full update for your installation to ensure you have all the latest packages installed.
With the latest kernel release all that we need to install is the firmware. We will be using the ATrpms repository.
1. Load up a terminal window if you are in the graphic interface.
2. Switch to the root user by entering the command “su -” (without the quotes) and typing in your root password
3. Edit the file /etc/yum.conf. Using nano we type the command “nano -w /etc/yum.conf”
4. If you have already configured yum to use the ATrpms repository then append “*iwlwifi* *80211*” to the end of the “includepkgs” line and skip the next setup. Otherwise continue on.
5. Add the following to the bottom of this file:
[atrpms] name=EL $releasever - $basearch - ATrpms baseurl=http://dl.atrpms.net/el$releasever-$basearch/atrpms/stable gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms gpgcheck=1 enabled=1 exclude=*kmdl*i586* includepkgs=*iwlwifi* *80211*
6. Save the file. In nano you press Ctrl-X, answer yes to the “Save modified buffer” question and then press enter on the file name to write.
7. If you have not previously setup ATrpms execute the following command:
rpm --import http://ATrpms.net/RPM-GPG-KEY.atrpms
8. Now execute the following command:
yum install iwlwifi-4965-ucode iwlwifi-3945-ucode
9. Now configure the ieee80211 module to start at boot:
cp -a /lib/firmware/iwlwifi-4965.ucode /lib/firmware/iwlwifi-4965-1.ucode cp -a /lib/firmware/iwlwifi-3945.ucode /lib/firmware/iwlwifi-3945-1.ucode
10. Reboot your system and you will be using the updated iwlwifi module.
Discussion
This didn't work for me unfortunately. CentOS 5.1, all updates from today.
mac80211: no version for “struct_module” found: kernel tainted.
mac80211: Unknown symbol ieee80211_led_rx
mac80211: Unknown symbol ieee80211_led_exit

mac80211: Unknown symbol ieee80211_led_tx
iwl3945: Unknown symbol sta_info_put
I wonder if I have to compile my own kernel :(
Same problem.
Problem
The same problem even after I installed ieee80211
Missing Dependency Problem
I tried the above steps and I am having a Missing Dependencies problem. I have been looking around and have tried the skip-broken plugin but I am still having the problem. Can anyone help?
Here is what I see
$ sudo yum –skip-broken install iwlwifi iwlwifi-kmdl-`uname -r`
Loading “fastestmirror” plugin
Loading “priorities” plugin
Loading “skip-broken” plugin
Loading mirror speeds from cached hostfile

Same problem like Duncan wrote … CentOS 5.2, all updated.

The guide has been updates. You can try it now. The issue was that Red Hat now include the iwlwifi driver in their latest kernel.
You will need to uninstall the old packages for this to work:
Thank you, thank you. You rock. This was exactly what I needed on how to load the iwl3945 drivers.
