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
