    Question ath9k does not work in latest Ubuntu 12.04 Kernel

    I have a Dlink DWA-556 pci express wireless card that uses AR5418 Wireless Network Adapter [AR5008E 802.11(a)bgn] (PCI-Express).

    This card works in the older ubuntu kernel 3.0.17 but it does not in the newer kernels and certainly not in the 3.2.0.29 - SAME MACHINE!

    Here is the
    Code:
    dmesg | grep ath
    output for 3.2.0.29

    [ 11.047317] ath9k 0000:01:00.0: Refused to change power state, currently in D3
    [ 11.047326] ath9k 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
    [ 11.150910] ath: Couldn't reset chip
    [ 11.150913] ath: Unable to initialize hardware; initialization status: -5

    And the same for the older 3.0.17-030017-generic kernel
    [ 17.547883] ath9k 0000:01:00.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
    [ 17.547891] ath9k 0000:01:00.0: setting latency timer to 64
    [ 17.681297] ath: EEPROM regdomain: 0x10
    [ 17.681299] ath: EEPROM indicates we should expect a direct regpair map
    [ 17.681301] ath: Country alpha2 being used: CO
    [ 17.681302] ath: Regpair used: 0x10
    [ 17.736460] ieee80211 phy0: Selected rate control algorithm 'ath9k_rate_control'
    [ 17.736852] Registered led device: ath9k-phy0
    I can give any other info you want, but the above seems to say it all.

    When I boot into the newer kernel, network manager or 'lshw -C network' does not even show the wireless interface.

    Any ideas? Thanks for your help.

    , copy and paste this command in the terminal (ctrl+alt+t) please:
    Code:
    wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script
    It will download a script and create a text file in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security, then reply back and attach the netinfo.txt file.
    Thanks

    Thanks for your time Wild Man.

    I am enclosing both the working & the not working versions of the output.

    Hi, does it have the same error's on 3.2.0.28 and 3.2.0.27?

    You can also reinstall the linux-image and see if that helps.
    Thanks

    Same chipset and kernel

    I'm curious to see why the ath9k module is not loading on the 3.2 kernel. Will you run the following?
    Code:
    sudo modprobe -v ath9k
    I have the same chipset and kernel and it works. Maybe ath9k project accidentally dropped detecting your devices pci id. I recently ask a question to the ath9k mailing list and someone very helpful responded. If you ask on the mailing list I would give detailed information about your adapter, like this:
    Code:
    lspci -nnk | grep -iA2 atheros
    02:00.0 Network controller [0280]: Atheros Communications Inc. AR5418 Wireless Network Adapter [AR5008E 802.11(a)bgn] (PCI-Express) [168c:0024] (rev 01)
    	Subsystem: Apple Inc. AR5BXB72 802.11abgn Mini PCIe Card [AR5008E-3NX] [106b:0087]
    	Kernel driver in use: ath9k
    Ath9k Mailing list: http://linuxwireless.org/en/users/Dr.../#Mailing_list


    My output of that script
    netinfo.txt

    Wild Man ..
    I will try to reinstall these kernels and try. It never worked with these newer kernels.
    I am curious as well, since something like this might have been the reason why it worked in 3.0.17. Let me explain. I had 3.0.11 when it was working and it never worked with the newer kernels that were installed through the update manager. But once I manually installed the 3.0.17 kernel and it worked in it. So, perhaps, if I manually install the latest kernel it might just work.

    Thanks. I will try and post an update.

    Hi, you can install linux-backports modules-cw-3.3 then reboot and see if that helps.
    Thanks

    I have tried the backports as well, but it did not fix.

    I'm now confident this is something to do with the kernel. I have tried a clean install and every time even with Fedora Core 17, OpenSuse 12, and live cds of Ubuntu or Linux mint it has failed. I tried debian 6 and it worked, but the kernel is 2.6.32 in debian.

    Now I am back with Ubuntu 12.04 and I moved to kernel 3.1.10, and its working.
    But not with any 3.2.x or the latest!

    I think like bakegoodz suggested I will have to write to ath9k project.

    Thanks.

    Sorry to interrupt, but have you read this bug about 12.04 LTS and ath9k driver?
