    Beware of kernel updates in Lucid

In the end, I followed drpjkurian's recipe and was immensely relieved to get WiFi working again this afternoon, ready for me to take the laptop to a meeting. I have another meeting (for which I'm secretary) on Thursday evening, so Lucid will have to wait until after that...

    Be careful -- the Kurian recipe doesn't quite work after the latest kernel update to Lucid, even though it worked before that update. For the correct recipe, see http://help.ubuntu.com/community/Wif...Driver/Atheros. Dr. Kurian has looked at it and says it's OK (see his comment earlier in this thread).

    I think it's far better to have this information in a Ubuntu (or Kubuntu) wiki, where it's easier to find than it is in a forum thread.

    Re: Madwifi installation for Atheros card in Karmic koala

    Great stuff - I upgraded to Lucid recently on my netbook (Acer Aspire One) and my big laptop ("Custom PC" built to order), both of which use the Atheros 5001. Wireless worked at first on the Aspire One, but then got flakier and refused to work. On the "Custom PC" laptop wireless flatly refused to work at all. I followed drpjkurian's recipe on both machines, and we are now flying again

    Thanks

    Re: Madwifi installation for Atheros card in Karmic koala

    Oops, I typed a bit too soon The "Custom PC" laptop is fine, but when I started up the Aspire One again after submitting the previous post it hung, and eventually gave up. I tried the extra steps listed in the wiki (making sure that both ath_hal and ath_pci are included in /etc/modules, and creating /etc/modprobe.d/options with the line options ath_pci rfkill=0), but to no avail. I tried wicd (which, interestingly, now seems to ba able to co-exist with network manager), and *that* told me after trundling round trying to authenticate that the password was bad! After opening up the wireless access point (removing encryption), and repeating the access attempt using wicd, it failed because it couldn't get an IP address. Looks as though I need to do some more digging...

    Hi Rainkap
    Let me share you one of my experience after Lucid.

    I was using Wicd from hardy heron to Karmic kaola. When I upgraded to Lucid, I got a weird message from Wicd stating that it is unable to get IP address. I switched over to Knetwork manager and it is robust connection again..
    I think it is a bug in Wicd

    Let me know yours... after trying network manager
    With regards

    I followed the steps on that page exactly (AFAIK). My wireless is still ridiculously slow.

    Double wireless device

    I'm only guessing, but it seems likely that the double path to the wireless device is responsible for the poor performance. The Kurian recipe is intended to establish a connection but doesn't attempt to deal with the performance of that connection.

    I don't know why you have a double path. It's interesting that they both have the same HW address, but wifi0 has a bunch of extra zeros.

    Re: Double wireless device

    I'm at my wit's end with it. Any suggestions for a non-Atheros replacement?

    Open the 'terminal' by navigating through Applications-->Accessories--> Terminal

    Now type the following commands in terminal

    1.
    Code:
    sudo nano /etc/apt/sources.list
    From there make sure you uncomment anything that starts with "deb" in there. So changer it from "#deb" to "deb" Something along thoes lines. To exit and save hit "CTRL+X" the answer "YES" to do you want to save, then finally hit "ENTER"

    2.
    Code:
    sudo apt-get update && sudo apt-get upgrade
    3.
    Code:
    sudo apt-get install build-essential libssl-dev
    4.
    Code:
    sudo apt-get install linux-headers-`uname -r`
    5.
    Code:
    sudo apt-get install subversion
    6.
    Code:
    sudo -i
    7.
    Code:
    sudo svn checkout http://svn.madwifi-project.org/madwifi/trunk/ madwifi-ng
    8.
    Code:
    cd madwifi-ng
    9.
    Code:
    echo "" >> /etc/modprobe.d/blacklist
    10.
    Code:
    echo "#Remove To Install MadWIFI Drivers" >> /etc/modprobe.d/blacklist
    11.
    Code:
    echo "blacklist ath9k" >> /etc/modprobe.d/blacklist
    12.
    Code:
    echo "blacklist ath5k" >> /etc/modprobe.d/blacklist
    13.
    Code:
    make && make install
    14.
    Code:
    echo ath_pci >> /etc/modules
    Restart your machine.
    It should work

    Well i use Wicd to connect to the wireless modem
    To install Wicd type the following commands in terminal
    Code:
    sudo apt-get update
    Code:
    sudo apt-get install wicd

    Kernal updates of your system will kill your driver. Well no need to worry about that.Just recompile your driver.
    For that you open a terminal and type the command
    Code:
    sudo -i
    and just repeat the steps from No 8. Your madwifi will cone back to life again.

    Best of Luck
    Dr Kurian

    Dear Dr Kurian,

    I have followed all your steps and I still couldn't bring up my wireless. I'm using an Acer 5820TG with Atheros AR8151. My installation is 10.04. The Ethernet portion works fine but I couldn't bring up the wireless.

    I'm fairy new in Ubuntu...

    Thank you!

    Re: Madwifi installation for Atheros card in Karmic koala

    Dear (K)Ubuteans,

    it seems this is the thread that never says die.

    I am trying to get 10.04 netbook remix working on an eee PC, 4G 701. I followed the instructions on the original post...

    01:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)
    Subsystem: Device 1a3b:1026
    Flags: bus master, fast devsel, latency 0, IRQ 18
    Memory at fbef0000 (64-bit, non-prefetchable) [size=64K]
    Capabilities: <access denied>
    Kernel driver in use: ath_pci
    Kernel modules: ath_pci, ath5k
    still no wireless. Any help you may offer would be greatly appreciated.

    Thanks,

    Simon Taylor
