    Default module b43 and kernel 2.6.32

    git clone Index of /git/b43-tools.git
    cd b43-tools/fwcutter
    make
    cd ..

    export FIRMWARE_INSTALL_DIR="/lib/firmware"
    wget http://downloads.openwrt.org/sources...8.10.4.tar.bz2
    tar xjf broadcom-wl-4.178.10.4.tar.bz2
    cd broadcom-wl-4.178.10.4/linux
    sudo ../../fwcutter/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta.o

    reboot your system

    There has been some headway progress into bcm4315 development as noted here. For users of BT4 with such chipset may want to try either updating their kernel or use compat-wireless package. Note that this is not an easy job and you maybe left on high and dry in terms of support with non-standard (vanilla kernel or otherwise updated wireless package) setup.

    Also as with using either newer kernel or compat-wireless package some of the injection capabilities will be lost. Users who updated their kernel may also realise that there are many areas to work on in order to get everything working again.

    IHaveNoIdea: Your chipset should be supported by b43. You should avoid using wl at all costs as it is a proprietary binary blob released by broadcom without monitoring capabilities. I suggest you to remove wl, blacklist it, reboot and check to see if you have wlanX interface rather than ethX interface. If you've rebooted and you see b43 is loaded but no wlanX interface, you may have acpi issues.. read into howto disable acpi and give that a shot.

    Apart from that bcm4311 is different to bcm4315, if they were the same many users with such chipsets would not be asking for help. bcm4315 I think is a stripped down version of bcm4312 with LP PHY coding which Broadcom never released any info to the public and therefore to the b43 devs.

    Leroy: You are using wl driver. I suggest you to remove wl and any traces of it off your computer, blacklist that module and then try again with b43. If no dice or you're coming up with error you may need to either update kernel or compat-wireless so that you may get some support. The use of wl is not ideal as I have mentioned before, Broadcom deliberately removed rfmon functionality out of their own driver.
