    How and where did you upgrade the kernel and did you include linux-image-extras?

    BCM4313 needs the firmware for the respective module:
    Code:
    wget http://media.cdn.ubuntu-de.org/forum/attachments/39/45/5007272-Broadcom_Firmware_fae7121.tar.gz
    sudo tar xvf 5007272-Broadcom_Firmware_fae7121.tar.gz -C /lib/firmware

    I wasn't aware that brcmsmac required firmware.

    As far as i know, every kernel since 3.0.xx works fine. Let's identify your device first:
    Code:
    lspci -nnd 14e4:
    And let's look at some diagnostics:
    Code:
    dmesg | grep wlan
