    Not able to authenticate in lubuntu 12.10 with Atheros card in netbook

    Hi all, basically, the problem is:
    lubuntu finds possible wireless networks, but for all of them it is throwing incorrect password errors. I will include some extra info to speed the process.
    Thanks in advance to everyone here.

    Easy answers: wired network works, the password I'm typing is correct.

    Hi again everyone.

    If someone there has at least some pointers on what to read, or where to start, that will be really helpful.

    Thanks again

    EDIT: one last thing, if switching to lubuntu 12.04 may fix the problem, please tell me so cause I'm willing to downgrade if that solves the issue.

    Re: Not able to authenticate in lubuntu 12.10 with Atheros card in netbook

    The ath5k driver has historically had problems with hardware encryption - not sure the current status, but disabling it has worked for me in the past - as a temporary measure you can try

    Code:
    sudo modprobe -r ath5k
    sudo modprobe ath5k nohwcrypt=Y
    If that appears to help post back and we can write it into your modprobe conf to make the change persistent

    Sadly, the problem persists. The sympton is the same with allo networks, but I found this:

    After typing the password (correct or incorrect), the following message appears:
    (32) Insufficient privileges.

    Oops sorry I read your original post quickly and misunderstood the issue

    I don't know about Lubuntu specifically but if it's using network-manager then yes typically only privileged users (sudoers) can create new wireless connections easily - is the account you are using a member of the 'sudo' group?

    In regular Ubuntu there's a workaround that involves creating the connection and explicitly unchecking the 'Available to all users' box, instead of simply trying to connect from the list of detected networks - if a Lubuntu expert doesn't chime in we can try to see if a similar process will work for you.

    Re: Not able to authenticate in lubuntu 12.10 with Atheros card in netbook

    Hi again steeldriver, that was the problem. The user involved didn't have permission to add new connections, thus throwing the error mentioned before.
    I added the user to this "sudo" group and now everything is working.

    Many thanks for your tip

    Regards
    Patrick
