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 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bcmwl in Ubuntu. https://bugs.launchpad.net/bugs/1095751 Title: bcmwl fails to build with 3.8 kernels [error: ‘struct cfg80211_ibss_params’ has no member named ‘channel’] Status in “bcmwl” package in Ubuntu: Fix Released Status in “broadcom-sta” package in Ubuntu: Confirmed Status in “bcmwl” source package in Precise: Fix Committed Status in “broadcom-sta” source package in Precise: Confirmed 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.
