    no wireless networks with atheros ar5001


    Hello,
    Recently my laptop crashed in an odd manner. I was stuck in a login loop ( even though I had disabled login on bootup). Upon entry of the login info, the screen would go black for a few seconds and then prompt me for the info again. Needless to say I reinstalled 9.10 but my wireless stopped working. In my frustration I installed beta 10.04 hoping that a newer release would have the cure.

    It seems my atheros card is seen, and driver is loaded, it just doesn't see any signals. I have blacklisted the Hal and other files including ndiswrapper etc, but to no avail.

    So in case some of you guys want to take a crack at this. . . . .

    Code:
    t@t-laptop:~$ ifconfig

    Ignoring unknown interface wlan0=wlan0.
    huh? Might that have something to do with it?

    Any help, guys, would be greatly appreciated.

    Cheers



    Hope you guys can help.

    Cheers,

    no wireless networks with atheros ar5001

    Hi, Squid1230--

    Can't find my notes on a similar problem a year or so ago...but if you go to ubuntu forums and search for "ubuntu 9.10 [or 10.04] atheros ar5001 no wireless" you should get at least one good hit. (I can't post the url due to not having posted enough in this forum.) There might be some help there. good luck!

    I'd suggest that you begin at the top.
    http://www.linuxforums.org/forum/wir...tart-here.html
    There is a bit more info that needs to be revealed before we can make the right choices. Please paste the requested info from the above link....use the code tags and remove any @ or www from your post and you shouldn't get the error message about posting links in the forums.

    Everything seems fine there.

    Does this return local networks?
    Code:
    sudo ifconfig wlan0 up
    sudo iwlist wlan0 scan

    Nothing much but it's worth a try.
    Code:
    sudo ifconfig wlan0 scan

    You have all the correct drivers and I don't see anything that might be conflicting with it....Try this
    Code:
    sudo ifconfig wlan0 up
    Code:
    sudo iwlist wlan0 scan
    You should see your access point if everything is okay....if not then try removing the ath5k module and reloading it.
    Code:
    modprobe -r ath5k
    Code:
    modprobe ath5k
    Repeat the first two commands and see if access points show up.
