    Help with Atheros AR5001 with Ubunutu 10.04

    I have a samsung N310 (GO) Notebook and installed Ubuntu on it. I used to have fedora but decided to move.

    Everything is working perfectly except the wireless. I can connect to the network but it is very buggy & drops connections frequently.

    Details from lspci

    Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)
    Subsystem: Foxconn International, Inc. Device e00c
    Flags: bus master, fast devsel, latency 0, IRQ 16
    Memory at f0100000 (64-bit, non-prefetchable) [size=64K]
    Capabilities: <access denied>
    Kernel driver in use: ath5k
    Kernel modules: ath5k

    It appears you are not alone (assuming you are using 10.04). The following link has a patched kernel that has worked for some, but not for others- might want to take a look at the thread:

    The patched kernel didn't work for me either, but installing Madwifi did. This thread tells you how. Though it was written for Karmic, it works for Lucid too.

    Re: Help with Atheros AR5001 with Ubunutu 10.04

    This may help someone. I have Atheros AR5001 and I have managed to make my wifi work with the following commands:

    sudo apt-get update
    sudo modprobe acer-wmi

    and it worked for a wile, but after I've updated the kernel, wifi stopped working. After some good hours of research I found that the problem is how the drivers are loaded. It has to be first acer-wmi and then ath5k.
    So this are the commands that worked:

    sudo modprobe -rv ath5k
    sudo modprobe acer-wmi
    sudo modprobe -v ath5k

    and I've put this in the /etc/rc.local so I don't have to put this commands every time I restart my computer.

    I may have spoken a bit too soon when I said that Madwifi worked. It's certainly an improvement on what I had before, but my wifi still has an annoying habit of losing the connection, and the only way I can get it back is to reboot.

    I've tried Zuperman1's solution, but on entering the command
    Code:
    sudo modprobe acer-wmi
    I get
    Code:
    WARNING: All config files need .conf: /etc/modprobe.d/ndiswrapper, it will be ignored in a future release.
    WARNING: All config files need .conf: /etc/modprobe.d/blacklist, it will be ignored in a future release.
    FATAL: Error inserting acer_wmi (/lib/modules/2.6.32-21-generic/kernel/drivers/platform/x86/acer-wmi.ko): No such device

    I have similar problem. After putting my Toshiba to sleep... I cannot connect to wifi. It just tries to connect, but doesn't. After couple of sleep/waking up, it connects.

    Hi

    Please install the following packages by synaptic package manager
    They are linux-backports-modules-lucid-generic and linux-backports-modules-wireless-lucid-generic. to solve the random blackouts...

    I can't find "linux-backports-modules-lucid-generic" on Synaptic. Should this be "linux-backports-modules-headers-lucid-generic"?

    Thanks, after trying Madwifi without success, trying new kernel that will freeze my laptop, this is the most useful post I read.
    For the moment, this works, and if the problem appears again, I will let a note on this forum.
    I dont know how you find this, but if this is one of the reason why this card does not work good, the answer is so easy that I am surprised nobody saw it before.
    Fingers crossed,
    Thanks
    Philippe
