    Default Unable to enable wireless on laptop, even though it's not greyed out.

    Hi all,

    I am using OpenSuse 11.4(32 bit) on my Lenovo B460 laptop, and as the title points, am unable to use wireless on it. The 'enable wireless' option from icon menu is not greyed out, however clicking it does nothing, it remains disabled.

    lspci -vv shows:

    "04:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)
    Subsystem: Broadcom Corporation Device 0510

    Capabilities: <access denied>
    Kernel driver in use: brcm80211"

    And iwconfig shows:

    lo no wireless extensions.

    eth0 no wireless extensions.

    wlan0 IEEE 802.11bgn ESSIDff/any
    Mode:Managed Access Point: Not-Associated Tx-Power=19 dBm
    Retry long limit:7 RTS thrff Fragment thrff
    Power Managementff

    vboxnet0 no wireless extensions."


    so it seems that opensuse knows my hardware but networkmanager doesn't!

    I have all broadcom packages installed as well as kernel-firmware installed. what am i missing?

    Thanks.

    NM knows about your hardware, it just doesn't think it is ready. Perhaps your
    wireless switch is in the wrong state. Please look at the output of

    Code:
    /usr/sbin/rfkill list
    You may have to install the rfkill package.

    The next thing to check is /var/log/NetworkManager to see if there are any clues
    there.

    In addition, peruse the output of dmesg for clues.

    Hi Thanks,

    I installed rfkill and issued the command rfkill list, here is the output:

    "0: acer-wireless: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
    1: ideapad_wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    2: ideapad_bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
    3: ideapad_killsw: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    4: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    5: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no"

    I tried rfkill unblock wifi and rfkill unblock all, but it didn't change anything. So it's clear that it's soft-locked, any chance to unlock it w/o installing windows?

    many thanks.

    It is the Acer WMI (Windows Management Interface) module that is blocking. As I
    don't have an Acer laptop, I have no idea what you do next. Until you clear that
    soft block, you will have no wireless. Sorry.

    I sthis openSUSE specific problem or kernel related problem?

    I have no idea what you do next
    Yeah but.. pclos gnome live cd detects and uses my wifi card on the same machine, can this help me resolve the problem? If so then where should I look?

    odd enough, lspci -vv from pclos live cd shows:

    Any more ideas as to why opensuse has access denied to "capabilities" of wifi hardware?

    thanks.

    Because you had not become root/got root privileges before you have entered "/sbin/lspci -vv" or something like it? I guess the user of your live CD may have that privileges or the filesystem permissions for are set in an other way on the live system.

    By the way:
    Code:
    /sbin/lspci -vvn
    will give you also the numeric ID's for your hardware which may be handy if searching for possible hardware related causes.

    Good luck

    This is actually a kernel problem. What kernel version does pclos use? The
    rfkill mechanism was changed over the past few kernel versions. If the other one
    is older, it may not be paying attention to the switch.

    Yep I think it's the kernel problem, pclos uses 2.6.33-x kernel.

    I don't think this problem has a solution yet..
    Hell I don't even know where to look next, so far I've blacklisted brcm80211 and wl module is loaded by default..even that doesn't do anything.

    Am waiting for 2.6.38 kernel as the following web-page indicates:
    acer-wmi: rfkill and bluetooth enabling doesn't work as in 2.6.37 though I don't know when will opensuse release the patch, so far it's the only major distro to support my sound and graphics together, alas no wifi
