First, have you tried googling CentOS 6 centrino N 6200, as I just did?
And the very first hit was posted 11 Jan 2011, and one comment was:
************
The Intel Wireless WiFi Link 6200AGN and 6300AGN Adapters are supported by the iwlagn driver in 5.5 and 5.6.

You will need the appropriate firmware installed, in this case iwl6000-firmware available from elrepo.org:

  • I am very new to installing Linux on laptops. I got it working on another Toshiba I owned without to much trouble, and then decided I wanted to experiment with KVM so I bought this laptop with an I5 chip.

    Anyway I tried modprobe iwlagn and the driver is not found. I then did a search for it using find and again came up empty handed. Googling for CentOS iwlagn seems to indicate that the module is a standard part of the CentOS 6 build. But I seem to be missing this on my installation. I will do a fresh installation and see if that does not install the module.

  • Before you do that, try searching the yum repo. I came up with a number of hits:

    Also, be sure that your radio is enabled in BIOS and after boot, once you have the proper packages installed. If the wifi indicator is not lit it may be disabled. Most laptops have a function key sequence to enable/disable wifi/bluetooth. You may need to toggle this to get your wifi radio to turn on.

    Let’s try again: please read what I write, not what you think I wrote.

    First, please stop top posting. Top posting, as I just explained to my wife, is what Outlook does these days. Add at the *bottom*, not the top.

    Secondly, the excerpt I included said that if you can’t, by default with the current standard repositories, yum install it, you might have to add the elrepo repository to your /etc/yum.repos by going there and installing the elrepo repository, and *then* yum installing from there. It also looks like it needs a kernel module, and that looks like it’s firmware from one of these packages: < http://elrepo.org/tiki/Packages#I>

  • The first thing I checked was the BIOS settings, and the radio is turned on.

    I have a clean install again and am still not working.

    I think the iwlagn driver was deprecated by the iwlwifi driver. In the dmesg output I saw that it lists with iwlwifi direver as being the Wifi Link AGN driver for Linux.

    Two messages jump out at me. Unable to init EEPROM and HARDWARE GONE?? I
    have tried toggling the radio on and off after booting but that does not seem to make a difference.

  • I put this aside for a while but I would still like to get this laptop working on my wireless Network. I found that it will work just fine with Linux Mint R14, but I want to use CentOS 6.4.

    The driver and firmware used by Mint are the same driver and firmware versions as found in CentOS 6.4, but they do not work with this adapter with CentOS 6.4. Any other suggestions on how I can get the N 6200 to work with CentOS 6.4?

    By the way I tried it with Scientific Linux 6.4 and it had the same dmesg errors as CentOS 6.4.

  • In Fedora, I had to install the iwl6000g2b-firmware to get the card to be seen. I haven’t tried CentOS on that particular machine, but I see there is an iwl6000g2b-firmware package. Worth a shot?

    This one.

  • Sorry, I was mistaken. My machine has an N6230, which worked out of the box with a minimal installation.
