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 Ubuntu Bugs, which is subscribed to 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’] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1095751/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
