Thanks a lot Marty , Gary and all other techies

it worked for me after upgrading the firmware

steps followed >>

1. Uninstall the bcmwl-kernel-source package by issuing the following
command on a terminal:

sudo apt-get remove bcmwl-kernel-source


2. make sure that the firmware-b43-installer and the b43-fwcutter packages are installed (of course you will need internet by others means):

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

3. type into terminal:

cat /etc/modprobe.d/* | egrep 'bcm'
(you may want to copy this) and see if the term 'blacklist bcm43xx' is there

if it is, type cd /etc/modprobe.d/ and then sudo gedit blacklist.conf

put a # in front of the line: blacklist bcm43xx

then save the file (I was getting error messages in the terminal about
not being able to save, but it actually did save properly).

4. reboot

Title:
  bcmwl fails to build with 3.8 kernels [error: ‘struct
  cfg80211_ibss_params’ has no member named ‘channel’]

Bug description:
  Upcoming 3.8 kernels have broken this DKMS package.

  P

  SRU request:

  [Impact]

   * As a result of this bug, bcmwl-kernel-source will fail to build the
  module against linux-generic-lts-raring in Ubuntu 12.04.

  [Test Case]

   * Enable the precise-proposed repository and install bcmwl-kernel-
  source (6.20.155.1+bdcom-0ubuntu0.0.2).

   * Install linux-generic-lts-raring

   * If the package installs without errors from DKMS with both the
  linux-generic and lts-raring kernels, then the patches work correctly.

  [Regression Potential]

   * The patches that I backported from 13.10 will preserve the current
  driver behaviour on linux-generic (3.2) and linux-generic-lts-quantal
  (3.5), thanks to the use of specific macros in the code which check
  the kernel version. As a result, no regressions of any kind can be
  expected on these kernels.
