Dell Inspiron N5050 wireless with Ubuntu 12.04

I come across some wireless problems on Dell Inspiron N5050. It is running Ubuntu 12.04 64-bit version.

 

  1. Remove existing bcm modules, bcmwl-kernel-source. Just make sure the package is removed

    apt-get autoremove –purge bcmwl-kernel-source

  2. In modprobe.d/blacklist.conf find the following lines

    # replaced by b43 and ssb
    blacklist bcm43xx

    change to

    # replaced by b43 and ssb
    # blacklist bcm43xx

  3. Install another bcm package support

    apt-get install firmware-b43-installer b43-fwcutter

  4. Restart the computer. And everything will be done.
