Dell WIfi Not working after 14.04 install

14.04 wireless dell broadcom

16,430

The Broadcom proprietary driver is incorrect for your device. Please hook up the ethernet, open a terminal and do:

sudo apt-get purge bcmwl-kernel-source
sudo apt-get update
sudo apt-get install linux-firmware-nonfree

Detach the ethernet, reboot and let us hear your report.

Below is wireless related info extracted from other forum advice. Looks like a kernel issue but I'm clueless how to solve. Thanks for any advice.
