problems after updates
After making the updates my wifi suddenly stopped working.
After going through various posts i realised it may be because of bcmwl-kernel-source upadation from bcmwl-kernel-source (188.8.131.52+bdcom-0ubuntu6.1) to 184.108.40.206.
I removed the new version and tried installing the previous version, but could not.
i ended up only in installing the new version.
I am unable to connect to my home wifi in the ubuntu12.04. I am able to connect to wifi in windows.
I was able to solve the problem by the following link.
