I am currently running a Gentoo on a Thinkpad T430u, embedding a Centrino Wireless-N 2230 card. The thing is I can't use my wireless card, even with the correct driver configs, and firmwares.

I have already done, the most relevant websites about the problem :

But I can't use my Wireless card on Gentoo (it works on Windows).

Here is a summary of my conf :

Device Drivers ->
    Generic Driver Options ->
        -*- Userspace firmware loading support
[*] Networking support  --->
    [*] Wireless  --->
        <*> cfg80211 - wireless configuration API
        <*> Generic IEEE 802.11 Networking Stack (mac80211)

        Optionally enable a Wifi LED:
        [*] Enable LED triggers

Device Drivers  --->
    [*] Network device support  --->
        [*] Wireless LAN  --->

            Select the driver for your Wifi network device, e.g.:

            [*]    Support for 802.11n (N-PHY) devices

            [*]    Support for HT-PHY (high throughput) devices
            <*> Intel Wireless WiFi Next Gen AGN - Wireless-N/Advanced-N/Ultimate-N (iwlwifi)
            <*> Intel Wireless WiFi 4965AGN (iwl4965)
            <*> Intel PRO/Wireless 3945ABG/BG Network Connection (iwl3945)
            <*> Ralink driver support  --->
                <*>   Ralink rt27xx/rt28xx/rt30xx (USB) support (rt2800usb)
    Generic Driver Options--->
        -*- Userspace firmware loading support
        [*] Include in-kernel firmware blobs in kernel library
        (iwlwifi-2030-6.ucode) External firmware blobs to build into the kernel binary
        (/lib/firmware) Firmware blobs root directory

And here is my dmesg about iwlconfig :

And ifconfig/iwconfig about wlan0 :

wlan0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
        ether 84:a6:c8:a9:3b:4d  txqueuelen 1000  (Ethernet)

        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

wlan0     no wireless extensions.

If anyone has an idea ? Because seriously I'm lost.

This question came from our site for professional and enthusiast programmers.

It seems your driver and firmware is loading correctly. Are you sure about it being wlan0? What does iwconfig say by iteself (without defining an adapter)? – user240914 Jul 26 '13 at 5:23
I have a problem with this card on Archlinux 4.1.3-1-ARCH x86_64, it fails to connect to my router if I put it in N-only mode. dmesg shows: denied association (code=18) – dhill Aug 9 '15 at 22:20

Sabayon 11 based on Gentoo seems to support the Centrino Wireless-N 2230 BGN in my Asus U32VJ without problems. Networkmanager under KDE does the rest:

There are hints that your drivers are more or less right:

lsmod | grep wifi
iwlwifi                57633  1 iwldvm
cfg80211              145999  3 iwlwifi,mac80211,iwldvm

The only disconnect is the inability to power off wireless either from the keyboard or Networkmanager.

If you like Gentoo then you will probably like Sabayon more.
