Ubuntu – Ubuntu 14.04 LTS wireless not working


So I have Ubuntu 14.04 LTS installed on my Dell studio 1555 and my wifi was working before but after a recent update and upgrade, it stopped working. Here are the contents of my wireless-info.txt file on this link:


My additional drivers window says i'm using a Broadcom 802.11 Linux STA wireless driver source, but I can't seem to access or detect any wifi access points. Any help will be appreciated as I really would like to have my wifi up and running again.


Best Answer

I do not believe the STA driver is correct. Please obtain a temporary internet connection, open a terminal and do:

sudo apt-get purge bcmwl-kernel-source
sudo apt-get update
sudo apt-get install firmware-b43-installer

Reboot and tell us if your wireless is working.
