    Default BCM43225 Wifi not working in 11.4 KDE and Tumbleweed

    Acer Aspire One 721-3620
    Linux 2.6.38.2-19-default x86_64 - Tumbleweed
    KDE 4.6.2 (4.6.2) "release 3"

    Fresh install of 11.4 and wifi wouldn't work.

    I read numerous threads indicating this device would work in 2.6.38 kernels so I upgraded to Tumbleweed to get this kernel version but still no joy.

    It shows not connected in Yast and Network Plasmoid.

    I really like this new baby laptop and would like to get the internal wifi working.

    /sbin/lspci

    This usually means that the wireless switch is off. You can check that with
    '/usr/sbin/rfkill list'.

    Thanks Larry I'll run that.

    I've fiddled/toggled the switch but without the led working it's impossibe for me to know when it's on or off.

    It's a combination of Fn key and F3, not a dedicated switch like I'm used to seeing and I'm guess that's complicating things.

    The switch would lead to a hard, not a soft, block. Try

    [code\
    sudo /usr/sbin/rfkill unblock all
    /usr/sbin/rfkill list
    [/code]

    Found this thread

    11.4 RC1 - Anyone gotten the Broadcom brcm driver working?

    Did this

    modprobe -r acer_wmi

    Got general protection fault

    Wifi is now working

    Not to try finding out what acer_wmi does and black list it.

    see my post above

    reading about acer_wmi now

    seems to control function keys.

    would be nice to have both working

    From my VERY limited knowledge it looks like acer_wmi hasn't been updated since 2008?

    So I don't have a working wifi switch on this netbook so to turn of wifi and bluetooth I can

    rfkill block all

    to turn off my wifi and bluetooth transmitters ???

    Blacklisting the acer_wmi driver solved my issue.

    The device boots and wifi now connects as expected.

    It would be nice, however, if I had the correct function hotkey functionality on this netbook.

    Thanks Larry :-)
