    Re: k42j Wire less problem.

    Hello and welcome to the forums,

    Which k42j model is it? There are several models http://www.asus.com/Search/?SearchKey=k42j

    Can you open a terminal, then copy and paste the following command, then post the terminal's response here?
    Code:
    lspci
    PS. I moved your post its own thread.

    Regards,
    uRock

    Not a fix but.....

    I have had similar issues with ASUS N73J with Windows 7 dual boot.

    Mine does connect to the wireless most of the time, but will sometimes continuously search just after startup - this seems to happen more often when windows has been hibernated or if it was the last OS used.

    Rebooting seems to get rid of the problem, but I would appreciate a fix too if anyone has one.

    Booting ubuntu twice is still faster than starting up windows once, so no huge problem!

    Can you post the output of lspci in a terminal, so that we can see which chip set the Asus card is using?

    Re: k42j Wireless problem.

    If you are using 11.04, then installing the linux-backports-modules-net-natty-generic package should do the trick with your chip set. I am getting this info from this bug report, where one of the last comments claims it fixed the problem. You can install via the Ubuntu Software Center or via the terminal with the following command;
    Code:
    sudo apt-get install linux-backports-modules-net-natty-generic
    As for 10.04 and 10.10 here is the Ubuntu documentation page explaining what to install. https://help.ubuntu.com/community/Wi...Atheros/AR9285

    That'll be great. It'll make life easier when someone searches for the same issue and can read that the fix works for others.
