I installed 14.04 on Dell Vostro 1500 but my network card isn't recognized. How do I get this installed? Was installed via USB that worked with no issues when OS is ran from USB stick.

[14e4:4311] (rev 01)

You need to connect to internet using some other adapter and run in terminal

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

and reboot.

If you do not have any other internet connection, then download these files.

http://mirrors.kernel.org/ubuntu/pool/main/b/b43-fwcutter/b43-fwcutter_018-2_amd64.deb http://www.lwfinger.com/b43-firmware/broadcom-wl-5.100.138.tar.bz2

Copy them to your home folder and run in terminal

sudo apt-get purge bcmwl-kernel-source
sudo dpkg -i b43*.deb
tar xfvj broadcom-wl-5.100.138.tar.bz2
sudo b43-fwcutter -w /lib/firmware broadcom-wl-5.100.138/linux/wl_apsta.o

For 32-bit systems download http://mirrors.kernel.org/ubuntu/pool/main/b/b43-fwcutter/b43-fwcutter_018-2_i386.deb

instead of the 64-bit package.
