I install Ubuntu 14.04 but I don`t have wireless connection because my notebook is a DELL Vostro 1500 with a proprietary broadcom 4311 wireless card. So I read that I have to install the broadcom drivers. Following forum instructions I install b43-fwcutter and firmware-b43-installer and then activate the broadcom driver as a proprietary controller. Then, I reboot but I had no controller nor wired connection. So I don't know how to recover the wired connection and what I have to do to have wireless connection with the broadcom card. Thank you Regards

The package bcmwl-kernel-source actually blacklists the ethernet driver!! It is incorrect for your Broadcom 4311 device. Please open a terminal and do:

sudo apt-get purge bcmwl-kernel-source
sudo modprobe b44

Your ethernet should now be working so that you can install the firmware for your wireless:

sudo apt-get update
sudo apt-get install firmware-b43-installer

After a reboot, both devices should be working.

The 'Additional Drivers' tool will happily offer to install the wrong driver for your wireless. Please ignore it.
