I have installed ubuntu 14.04 on my dell 3421 laptop but my wifi is not working. It is showing it has a proprietary driver, how do I get it to work?

Connect your PC to mobile phone(connected wifi or mobile data) and turn on USB tethering. Then run "sudo apt-get update" and install "Additional Driver" in the software center if don't have installed. Then find your wireless driver in "Additional Driver" and install it. This way solved for my dell.

I had the same problem, but it was no longer going to software and updates, then click into additional drivers and finally here you must choose the option which says Broadcom 802.11 Linux STA .....
