I have installed Ubuntu 14 and can't connect to WiFi. Tried to find solutions by myself but still things don't work out.

Steps I have taken:

  1. Went to Software And Updates -> additional Drivers and used Broadcom 802.11 Linux drivers
  2. Used iwconfig command, found that wlan0 doesn't exists
  3. Installed linux-firmware-nonfree package - wlan0 shows now up

After these steps I still can't connect to network and I'm getting following error in toolbar:

WiFi is disabled by hardware switch.

You have installed a wrong driver for this adapter.

Run in terminal

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

and your Wi-Fi should work.
