I have the following wireless network controller:

03:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 2200 [8086:0891] (rev c4)

Subsystem: Intel Corporation Centrino Wireless-N 2200 BGN [8086:4222]

Kernel driver in use: iwlwifi

It works well on Ubuntu 14.04.1 LTS. But if I want to use a linux-libre as kernel, it fails due to lack of related firmware on linux-libre.

How can I install the firmware?

  • If you're willing to install proprietary firmware on linux-libre, doesn't it defeat the purpose? Why don't you just use Ubuntu with the standard kernel?

  • Yes it does, but using a proprietary bios on your computer does defeat the purpose too… That is not a sole point to reach, It's a road to freedom and you should be able to go as further as you can. In my case there is no other other solution available, and believe me, I am truly upset for this. Commented Sep 9, 2014 at 22:23

  • This is relevant also for several ThinkPad laptops, e.g. X230 and T430. blog.burntsushi.net/lenovo-thinkpad-t430-archlinux

The firmware for the 2200 is located in the Ubuntu package linux-firmware - the driver is provided by intel, but not the source code. You can find specific firmware downloads at intel.

  • It is found in linux-firmware; not linux-firmware-nonfree.

  • @chili555 You are correct - I will amend the answer. There's something in the -nonfree that my Dell needs to run properly, and I have forgotten what it is. Commented Sep 10, 2014 at 20:43
  • Package linux-firmware is instralled and so is the iwlwifi-2000-6.ucode firwmware file, but when I log into Ubuntu with linux-libre kernel, wireless doesn't function at all. I checked and found even iwlwifi kernel module is loaded too. Commented Sep 11, 2014 at 11:01
