    Intel 6205 wireless not working with Lenovo W520

    Loving the new W520... very fast, if only the wireless would work. Unable to get wireless interface functioning, won't even show up in ifconfig. I've appended requested wireless information, thanks in advance for any assistance.


    1) Machine Brand and Model (PC/Laptop):
    Lenovo W520
    Intel Centrino Advanced-N 6205
    Note: Wireless switch on lefthand side enabled, bluetooth led lights up but wireless does not.

    2) Wireless Brand, Model and Wireless Chipset:
    $ lspci -nn

    03:00.0 Network controller [0280]: Intel Corporation 6000 Series Gen2 [8086:0085] (rev 34)

    3 ) check interface:
    ifconfig does not show wireless

    $ iwconfig
    lo no wireless extensions.

    eth0 no wireless extensions.

    4 ) Check for modules:
    $ lsmod
    ...
    iwlagn 215351 0
    iwlcore 139688 1 iwlagn
    mac80211 269644 2 iwlagn,iwlcore
    cfg80211 167809 3 iwlagn,iwlcore,mac80211
    ...
    5) Kernel boot messages
    $ dmesg

    Check first if you have a button to activate Wireless on your Lenovo.

    There is a switch on the lefthand side of laptop, this is in the on position. Additionally, there is an fn+F5 key combo that should toggle wireless. The key combo appears to have no impact. The wireless switch on the left hand side of laptop appears to turn off bluetooth, but does not light the wireless led (nor does ifconfig show wireless in either position). If I've missed something, please let me know... would love a simple fix

    Ok, now you could test to install additional drivers, System-> Additional drivers or something like this, Im on Kubuntu, so its different. Try to see if you can install some drivers maybe.
    Im not the expert for Wireless but maybe this site could also help: https://help.ubuntu.com/10.10/index.html

    Could have sworn that was what iwlwifi provided. At least that was what the intel driver site led me to believe. I double checked the drivers offered on http://intellinuxwireless.org/?n=downloads and was able to confirm that the driver is already present in /lib/firmware and a diff confirmed it was the exact same version. i.e. I think ubuntu managed to pull down the proper drivers, and that a manual installation was unnecessary.

    I suspect the drivers I have came from running this install

    sudo apt-get install linux-backports-modules-wireless-maverick-generic

    Should I have used a different set of drivers?

    Why do you have a backports driver?
    I have also Intel and it worked out of the box on Ubuntu 10.10, maybe thats the problem.
    When you installed the first time do you mean you did not have Wireless and then installed from the backports?

    With a fresh 10.10 install the wireless drivers did not work. I have roughly 5 years experience using ubuntu and with the exception of a broadcom card I've had little trouble with wireless cards and ubuntu. Unfortunately, with the Intel 6205 and the Lenovo W520 laptop I ran into some difficulties. After some research I found many suggested installing the backport drivers, so I gave that a try.

    Please let an old fan of Intel see:
    Code:
    dmesg | grep iwl
    rfkill list all
    Thanks.
