[RESOLVED] wireless - Intel Corporation Centrino Wireless-N 1000

Postby jameslast » 2011/07/12 15:38:07

Dear All,

I'm releaving a HP Probook 4710S from it's native Vista :=)

First of all let me say I'm happy because CentOs 5.6 handles it's Ati Radeon graphic
flawlessly, unlike other Distro's I tried on this type of machine. So thumbs up for CentOs!

But now I've come to a stop on the wireless card.

gives me :
# Intel Corporation Centrino Wireless-N 1000

So I had a look at http://wiki.centos.org/HowTos/Laptops/Wireless, but found no clues on this type of card.

I found a driver on this site : http://www.intellinuxwireless.org/?n=downloads
and downloaded

I then utarred it , the README says :


The iwlagn driver will look for the file iwlwifi-1000-5.ucode using the
kernel's firmware_class infrastructure. More information can be found under
Documentation/firmware_class in kernel source. In order to function
correctly, you need to have this support enabled in your kernel. When
you configure the kernel, you can find this option in the following

Device Drivers ->
Generic Driver Options ->
Userspace firmware loading support

You can determine if your kernel currently has firmware loader support
by looking for the CONFIG_FW_LOADER definition on your kernel's

In addition to having the firmware_class support in your kernel, you
must also have a working udev and uevent infrastructure configured.
The steps for installing and configuring udev are very
distribution specific.

Once you have the firmware loader in place (or if you aren't sure and
you just want to try things to see if it works), you need to install
the microcode file into the appropriate location.

Where that appropriate location is depends (again) on your system
distribution. You can typically find this location by looking in the
udev scripts of your distro, the default is /lib/firmware.

Installation of the firmware is simply:

% cp iwlwifi-1000-5.ucode /lib/firmware

You can now load the driver (see the INSTALL and README.iwlwifi provided with
the iwlwifi package for information on building and using that driver.)

I'm assuming the kernel is ok, so I just performed
cp iwlwifi-1000-5.ucode /lib/firmware

And ...that's pretty much the end of my knowledge. The network manager is not seeing any wireless networks .

I think I have the right driver, but what to do next?

Thanks already for any help.

ElRepo has firmware for this adapter to be used with the iwlagn driver which is native in CentOS5.5 and 5.6

The firmware you downloaded may or may not be the same. Intel mentions that it should be used with the native iwlwifi driver, and that the minimum kernel for this firmware is 2.6.30, indicating you should have better luck with CentOS6.

The output of
Code: Select all
lspci -nn | grep Centrino

will provide the vendor:device id pairing for this card (8086:nnnn), which allows you to verify whether that card is indeed supported by the ElRepo firmware.

Hi All,

thank you for the reply, René.

After reading your post this morning, I installed CenOs 6 and....guess what?


Needles to say I'm very happy and impressed.

Grt, James
