    wrong wifi controller recognized (Intel Advanced-N 6230)

    I installed ubuntu 13.10 on my Dell XPS 13 (L321).
    Since then my wifi is really unstable meaning that I can't connect to wifi connections.
    After a while looking into the problem I recognized that also the Bluetooth is missing.
    Apparently the wifi controller in not recognized correctly. (It should be: Intel Advanced-N 6230)

    How can I fix this?
    Thanks!

    Here some more information:

    It kinda look s like it's OK
    And I'm pretty sure the same driver would be in use regardless.

    Were you using another version of Ubuntu or Linux, before?

    Nope. Before it was installed win8.
    Hm I bought this notebook over eBay. Now I'm wondering if the adapter was replaced. : )

    But despite of this it does not work properly. I can see most of the time all the surrounding wifis but I can't really connect to them. I guess 1 of 30 times trying it works for about 2 mins. (And after this sometimes it can't find the wifi anymore; also the signals appears to be really weak)

    Re: wrong wifi controller recognized (Intel Advanced-N 6230)

    Please help. I can't find a solution for this problem.
    It's a pain to be not able to use the wifi.
    And if this is a hardware problem it would be good to know.

    sudo modprobe -r iwlwifi
    sudo modprobe iwlwifi 11n_disable=1
    If it helps, we'll make it permanent.
    Now I'm wondering if the adapter was replaced. : )
    No doubt.

    Yes, one of them. I tried about 6 different wifis.

    No doubt that it was replaced? Hrm could it not be similar to this http://ubuntuforums.org/showthread.php?t=2003669 ?

    This is the Result:
    Code:
    jguth@jguth:~$ sudo modprobe -r iwldvm
    [sudo] password for jguth: 
    jguth@jguth:~$ sudo modprobe -r iwlwifi
    Error: missing module name.
    FATAL: Error running remove command for iwlwifi
    jguth@jguth:~$ sudo modprobe iwlwifi 11n_disable=1
    jguth@jguth:~$
    There is not really an improvment.

    Thanks for the help!

    I fail to see the similarity to your case. The thread you linked is a case of a very new device that didn't work on a very old version of Ubuntu. Your case is instability on a very current Ubuntu version. I suspect the Ebay seller -- best case -- copied and pasted the wrong listing or -- worst case -- substituted a slightly lesser wireless card hoping you'd never notice or care. You could point out his mistake and ask for a refund or replacement or just try to get the 5100 working properly. Googling up 'Ubuntu Intel 6230' isn't going to help you in any way; you don't have one.

    I am troubled by this:
    jguth@jguth:~$ sudo modprobe -r iwlwifi
    Error: missing module name.
    FATAL: Error running remove command for iwlwifi
    Please see what's loaded now:
    Code:
    lsmod | grep iwl
    Let's try to make the 11n parameter permanent for a moment and see if it helps:
    Code:
    sudo -i
    echo "options iwlwifi 11n_disable=1"  >>  /etc/modprobe.d/iwlwifi.conf
    exit
    Reboot and tell us if there is any improvement.
