    Let's poke it a little:
    Code:
    sudo modprobe b43
    dmesg | grep b43
    dmesg | grep 0c:00
    Thanks.

    Re: Broadcom BCM4311, Ubuntu 12.04 / 13.04

    Hi
    I have a slightly different - if not weird - problem in helping out a mate with an Acer Aspire 5720 with a BCM4311 wireless device. The b43 module loads ok from either a basic install or using "apt-get install linux-firmware-nonfree" and it connects ok with a couple of wireless routers but will not complete a login with a ZTE MF66 broadband modem. It recognises the MF66 and attempts to connect but fails every time. Before you ask, the connection to the MF66 has been separately verified.
    It seems like there is a compatibility issue between the device driver and the MF66 giving some sort of handshake issue.
    No joy from dmesg.
    Any clues for this one? Just about to revert to a usb device.

    Hi Chili555,

    That's impressive and simple to implement. But will it work for a similar problem on my new Toshiba Sat Pro C850 as well?

    Or, do I need a slightly different (but similar) work around?

    Please help.

    Mike

    Does your C850 have the exact, exact same device?
    Code:
    lspci -nn | grep 0280
    Is it 14e4:4311? If so, then yes, indeed. If not, post the result in a new thread and I'll be happy to help.
