    Karmic: Wlan Atheros AR928X ath9k: no fix works

    Hello

    I've been looking around since yesterday for a fix and tried several fixes to get my wireless ath9k to work on Karmic but in vain

    -Tried removing ath from blacklist
    -Tried to use wicd

    In all cases, the wireless disconnects after something like 10 minutes and I can't reconnect. None of this happens on Jaunty.

    So I can't install Karmic because I can't install the language packages nor use it (and I don't have wires everywhere in the house). So I'm stuck with Jaunty.

    Other than recompiling the kernel with ath9k, is there any other way?

    Thanks

    Is it supposed to work on the liveCD? Because it didn't so, I want to make sure that, if I install it again this trick could work.

    Someone named sebz_ posted a solution that worked fine!

    I commented the ath_pci blacklist in /etc/modprobe.d/blacklist-ath_pci.conf.

    You check if ath9k (or ath5k) is loaded in /etc/modules

    echo ath9k | sudo tee -a /etc/modules

    Then you install

    linux-backports-modules-karmic and linux-backports-modules-wireless-karmic-generic (and linux-backports-modules-wireless-karmic-generic-pae if you can but I didn't need it)

    Reboot and all should be fine!

    This seemed to work for me with Karmic Koala on an eeePC 1000HE. (I assumed "commented" meant "commented out.")

    Simply installing the two backports-modules worked for me on this Acer laptop with:

    Code:
    06:00.0 Network controller: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) (rev 01)
    It was using ath9k, and still is (presumably a newer version), so I didn't bother with the system file edits. Working so far....

    Famous last words.

    Re: Karmic: Wlan Atheros AR928X ath9k: no fix works

    Hi Prosis,

    I was having the same problem with my Sony Vaio X111. I had tried everything I could (installing madwifi, ndiswrapper, turning of WPA, etc) but couldn't fix it.

    I installed the 2 backport packages as you said, and it is much better.

    Before the update:

    - signal strenght was always between 20% and 65%, even if I was only a couple of meters from the base station
    - hundreds off log messages from wpa_supplicant (disconnecting, searching, negotiating, reconnecting)
    - needed to kill / restart my connection manually every hour or so.

    After the update:

    - signal strenght is 100%
    - no more error messages on log files
    - the connection is stable.

    Thank you!

    I also tried the "solution" from drpjkurian, and it also shut down my WiFi. I then tried the solution you give here. During the install process, there was a warning message and a suggestion to install one additional package. At first - my WiFi was working great - but I had to boot in low-graphics mode. After I installed the additional recommended package - everything was fine. My WiFi no longer cuts out on me, but I must say that my page load times seem a bit longer. Anyway - things are MUCH better now. Thanks for your post.

    Thank you for this, it saved my laptop from getting Windows back.

    It work just perfect on my Acer Aspire 5536 with the Atheros 928X ath9k. Now signal strength is about 80% (before it maxed out at about 30%). Now I just need to see if the dropped connections problem goes away.

    Cheers,
    Nikolaj
