    BCM4313 module issues (12.10)

    I have recently installed Ubuntu 12.10 on a Dell Latitude E6520 with a Broadcom BCM4313.
    Code:
    Linux rubuntu6246 3.5.0-21-generic #32-Ubuntu SMP Tue Dec 11 18:51:59 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
    After hours of digging through various threads, blogs, and documentation detailing how different people were able to get their BCM4313 to work on 12.10, I stumbled across the following commands, which worked like a charm after I had removed all other broadcom-related packages:

    Code:
    apt-get install --reinstall linux-headers-generic
    apt-get install --reinstall bcmwl-kernel-source
    rmmod wl
    modprobe wl
    The problem is that I need to perform these steps every time I reboot the machine, which is quite an inconvenience.

    Here is the output that is displayed when re-running the commands. Shortly after the final modprobe command, the Network Manager icon indicates that it is negotiating a DHCP lease and connects to the local wireless network.

    Code:

    I have also attached a copy of the output generated by LSMOD, which was run before the software reinstallations and module insertion.

    Thank you in advance for any help. Let me know if there is anything else I can do to help you help me.
